# OmniShade Mobile-Optimized Shader for Unity {% embed url="" %} Fully-featured stylized shader for Unity, optimized for mobile devices. Packed with all the latest techniques, yet blazingly fast due to a progressive system of calculating only what it needs to. ### Get it at Unity Asset Store * [**OmniShade**](https://assetstore.unity.com/packages/vfx/shaders/omnishade-mobile-optimized-shader-215111) * [**OmniShade Pro**](https://assetstore.unity.com/packages/vfx/shaders/omnishade-pro-mobile-optimized-shader-213594) ### One shader to rule them all **OmniShade** is a highly performant shader designed for mobile devices. It is packed with a multitude of techniques allowing it to achieve almost any look from realistic to toon to anime, yet also blazingly fast due to an adaptive system of calculating only what it needs to for any feature set. It was designed to bridge the gap between Unity's Standard Shader and mobile shaders, but can often look even better than desktop-class shaders due to its high level of stylization, combination, and customization. All of the sample images above were rendered using only OmniShade, the variety of expression is limitless. It can be used for a game with complex lighting or simple sprites -- regardless, the performance is always optimal. It is quite possibly **the only shader you will need for your entire game.** ### Features All of the below **can be used in any combination,** **with optimal performance.** * Color adjustments + desaturation * Diffuse soft lighting * Specular map + hair highlights * Rim light * Reflection * Normal map * Occlusion map * Emissive map * [MatCap](https://www.youtube.com/watch?v=qPVUW1tFT-0) * [Vertex colors for vertex painting](https://www.youtube.com/watch?v=PgEv3Au6X08) * Detail map * [3 blended layers](https://www.youtube.com/watch?v=PgEv3Au6X08) * Transparency mask * Height based colors * Shadow overlay * Vertex-sway for vegetation * Outline * [Anime ramp lighting](https://www.youtube.com/watch?v=5SPnj8zSPMw) * Fade with camera distance * Flat shading * Environmental lighting, fog, and light probes * Shadows + shadow colors * Unity baked global illumination support * **(Pro feature)** [Triplanar projection texture mapping](https://www.youtube.com/watch?v=U_K1lnhjlFI) * Full access to culling and blend settings + presets for opaque/transparent objects * [Highly tunable controls for all features](https://www.youtube.com/watch?v=B_ynmnnJvfg) **...see** [**Features** ](#features)**for in-depth specs of each feature.** On top of this, we also include: * **Built-In** and **URP** pipeline support * **Progressively adaptive performance** which automatically detects and generates the minimal shader variant for any given set of enabled features. * **(Pro feature)**** Optimized shader stripping** on a per-material basis for minimum build size and memory * **(Pro feature)**** Custom fallback shader** on Open GL ES 2, so your game looks great for even grandma * Script for animating textures in the shader * Slick collapsable shader UI, easily extendable * Set of tutorial demo scenes It's true, the Standard Shader is still too slow for mobile devices. And let's face it, giving an artist Shader Graph is like giving a baby a gun. But it doesn't mean you have to compromise on your game's looks. ![](/files/NNH3dzSyhYv5eA8NfSv5) # Getting Started * For **Built-In pipeline**, start by opening the sample scene in *OmniShade/Samples/Basic/Basic.unity*. You can safely ignore any warnings regarding the URP version of the shader if you do not have URP packages installed. * For **URP pipeline**, start by opening the sample scene in *OmniShade/Samples/Basic URP/Basic URP.unity*. If you need help installing URP, follow the [Unity URP Installation Guide](https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@15.0/manual/InstallURPIntoAProject.html). 1. Feel free to move the camera around and browse the sample materials in the scene, and experiment with the shader's parameters to get an idea of what the shader can do. 2. There are other sample scenes as well, each demonstrating a different technique of the shader. Check those out too for ideas on how to use the shader. 3. If you are using the MatCap feature, for tips on creating your own MatCaps, read *OmniShade/Samples/MatCap Textures/How to create MatCaps.txt* 4. For more details, refer to the [Features](/documentation/features), [FAQ](/documentation/faq), and [Optimization Tips](/documentation/optimization-tips). 5. Start creating your own materials with OmniShade. You're on your way!
# Features ### Shader Features #### Diffuse Diffuse softness is adjustable, along with brightness and contrast. There is also an option to enable per-pixel diffuse, which will get you better point-light quality on low-poly meshes but this is more computationally expensive. On scenes with lightmapping baked in, the diffuse light is disabled for static lightmapped objects since this is baked in. The toggle for Baked And Dynamic Lights enables the object to receive both baked and dynamic lights (from point lights only) on URP.\ **Note**: *Spot lights are supported only on URP. For Built-In Pipeline, you can use a* [*Projector*](https://docs.unity3d.com/Manual/class-Projector.html) *to achieve nearly the same effect as spot light. On URP, Additional Lights should be set to Per Pixel.* #### Specular Used for metallic or shiny objects. Supported for 1 directional light, with an optional specular map. The color defaults to using the same as the directional light's, but there is an override color as well. Brightness and smoothness adjustable as well. On the specular map, the red channel masks the specular intensity, and the alpha channel the specular smoothness. There is also an option for Specular Hair, which has brushed highlights for effects like hair or brushed metal. When using Specular Hair, the normal map has no effect. Rather, the Specular Map is used to slightly shift the normals to give variance. On scenes with baked directional lighting, the lighting direction is sampled from the directional lightmap instead. #### Rim Light Highly versatile effect for simulating indirect lighting or subsurface scattering like skin. Tunable color, brightness, and contrast parameters. Also supports multiple blend modes, invert, and rim direction as well. Can even be used to fade the transparency of outer edges to create fuzz effects. #### Reflection If enabled, by default it uses the scene's skybox material from Lighting Settings. You can override the cubemap texture in the material. If Mask With Rim is enabled, it works in pair with the rim's fresnel effect to strengthen the reflection at the edges. Reflection amount and color are adjustable. Can also mask it with the Specular Map. #### Normal Map Supported for all light sources including diffuse, specular, lightmap, rim, MatCap, and even in the triplanar mapping as well. Strength is adjustable. Be sure to set the Texture Type for the texture as Normal Map. #### Occlusion Map Occlusion maps store local shadowing, or ambient occlusion in lookup textures. Supports color, brightness, and UV1 and UV2. #### Emissive Used for objects that emit light. Supports HDR color with an optional Emissive Map. The HDR color slide allows adjusting the intensity above 1 in HDR workflows. #### MatCap Integration of [MatCaps ](https://youtu.be/qPVUW1tFT-0)with Unity's lighting system is one of the key features of OmniShade. MatCaps are enormously powerful, able to capture the entire lighting of a scene in a single texture. They are popular in 3D sculpting but also highly effective in scenes where the camera does not need to move much, as the only short-coming is the lighting is only captured from a single angle. Supports blending with Multiply or Multiply Lighten modes, with brightness and contrast parameters. There is also a Perspective Correction option which can be disabled for improved performance if you don't need it. Finally, the Static Rotation option allows locking the MatCap to a manually set angle, useful if you absolutely do not want the lighting to move with the camera. Also, check out[ ZBrush MatCaps](https://pixologic.com/zbrush/downloadcenter/library/) to download more or create your own. #### Vertex colors Used for [vertex painting colors](https://www.youtube.com/watch?v=PgEv3Au6X08) with tools such as [Polybrush](https://www.google.com/url?sa=t\&rct=j\&q=\&esrc=s\&source=web\&cd=\&cad=rja\&uact=8\&ved=2ahUKEwjQ-o6skYn2AhWKr4sKHfJ2AKEQFnoECAYQAQ\&url=https%3A%2F%2Funity.com%2Ffeatures%2Fpolybrush\&usg=AOvVaw1oZ_Ik8CVTOiNQKhpMcJpc). Supports all RGBA channels. Toggleable on or off, with a contrast setting. The channels can be used as a mask on the three texture layers and the Detail Map for texture painting effects as well. Be aware that the color resolution depends on the vertex count in your mesh geometry. #### Detail map Detail maps, or secondary maps, blend in grainular details to the base texture. The alpha-channel of the texture is used as a blend factor. Supports multiple blend modes, and UV1 or UV2. Also supports adjustment of color, brightness, and contrast. Toggling the option to apply the detail map to the lighting will apply the detail as a mask to the Diffuse and MatCap lighting instead, which is useful for adding detail in the lighting for effects like sparkles. There is also an option to mask the detail map with the vertex color alpha channel, useful in vertex painting. #### Layers Similar to Photoshop layers, these are useful for decals or [terrain splatting](https://www.youtube.com/watch?v=PgEv3Au6X08) with tools like [Polybrush](https://www.google.com/url?sa=t\&rct=j\&q=\&esrc=s\&source=web\&cd=\&cad=rja\&uact=8\&ved=2ahUKEwjQ-o6skYn2AhWKr4sKHfJ2AKEQFnoECAYQAQ\&url=https%3A%2F%2Funity.com%2Ffeatures%2Fpolybrush\&usg=AOvVaw1oZ_Ik8CVTOiNQKhpMcJpc). The layers are rendered in order from 1 to 3, so that layer 3 is on top. Supports multiple blend modes, and layer masking with the layer texture alpha-channel. Also supports masking with vertex color RGB channels for texture painting. Brightness and transparency adjustable. #### Transparency mask This modulates the final alpha of the object, useful for effects like smoke or waterfall effects. Input texture can be either alpha or grayscale based. Alpha and contrast adjustable. #### Height Based Colors Highly versatile effect, this is useful for height-based colors such as simulating the water line, or even indirect lighting from above and below. Height can be set in either local or world space. Color, thickness, edge thickness, and blend mode can be adjusted. You can also apply a Height Texture as the background with this effect. #### Shadow Overlay This effect projects a texture over objects using world-space positions, useful for creating global effects like rolling cloud shadows or tree leaf overhangs. It is fully animatable through the shader, either as a scrolling or ping-pong movement. Speed and sway amount are adjustable. #### Plant Sway Useful on vegetation to simulate movement by wind. Uses a vertex-shader based animation dependent on object height. Animation is fully done in the shader, and plant type can be set for plant, leaves, or based on vertex colors (which uses the alpha channel). The sway amount and speed are adjustable. The phase variation affects the synchronicity of the objects affected. #### Outline Support for adding a colored outline around the object. Options to adjust outline width, outline Z position offset to reduce interior outlines, hide interior outlines completely, and outline grouping. #### Anime Easily convert to [anime-styling](https://www.youtube.com/watch?v=5SPnj8zSPMw) with a toggle. There are 3 adjustable luminance ramps with 2 threshold settings, and a softness parameter. Tune the softness to avoid overly harsh shading edges on polygons if you notice them. Outlines can be created too through only the shader, by rendering the mesh twice with Vertex Extrude and Culling set to Front (see the included Unity-chan sample). #### Camera Fade Fades the transparency of the object as it approaches the camera. Use Fade Start Distance and Fade End Distance to adjust when the fading occurs. #### UV Tile Discard Toggle portions of a model on or off at runtime based on UV coordinate values. [UV Tile Discard details](#https-www.poiyomi.com-special-fx-uv-tile-discardshader-features). #### Environmental Lighting Support for Unity's Environmental Lighting settings (accessible via the Lighting Window), including Skybox, Gradient, or Solid Color. Also support for dynamic global illumination from Light Probes. #### Fog Supports all of Unity's fog modes. Toggleable on or off. Fog settings can be configured from the Lighting Window. #### Shadows Supported for 1 directional real-time light on Built-In, and all lights on URP. Shadow Color is adjustable. Be sure to tune the Shadow Distance parameter in your Lighting Settings for the best quality. There is a Receive Shadows toggle in the shader to disable shadow calculations as well. On scenes with baked lightmapping, the shadow is disabled for static-baked objects. If you need realtime shadows on a light-baked scene, you can either used Mixed Lighting on your light with Subtractive Mode in the Lighting Settings, or simply add another real-time directional light to the scene and set the light's Culling Mode to not affect baked objects. #### Culling and Blending Settings All the culling and blend mode settings are exposed and configurable in the shader, with predefined presets for convenience as well, eliminating the need to create separate shaders for slightly different render states (ie., Transparent, Cull None, Additive, etc). #### Flat Shading Great for stylized low-poly blocky looks. Fully compatible with all lighting including diffuse, specular, rim, MatCap, and normal mapping. #### Unity Baked Global Illumination Support Fully supports Unity's baked global illumination. The proper albedo colors are output for proper indirect lighting effects. The scene must have a baked light source, objects to bake must be marked Lightmap Static, and you can bake the scene from the Lighting Settings window. #### **(Pro feature)** Triplanar projection texture mapping [Triplanar mapping](https://www.youtube.com/watch?v=U_K1lnhjlFI) is a peculiar but extremely powerful effect, useful for terrain, procedural geometry, and modular environments. It requires no UVs at all, and works by projecting a texture from all 3 axises onto the geometry. Supports a separate texture from the top side as well, useful for simulating grass or snow coverings. Blend sharpness can be adjusted. If Use UV For Sides is toggled, then UV coordinates instead of the triplanar projection on the sides of the object. Full normal map support as well. ### Performance #### Progressively adaptive performance The real magic of OmniShade is here, in it's adaptable performance. Through the use of shader variants, it only creates shaders with the minimal calculation needed for any set of enabled features, which it is able to detect automatically. So, you can use OmniShade to create a simple game with only diffuse lighting, or a realistic one, or any combination in-between, and the performance will always be optimal. This allows precise and granular control over the quality and performance to achieve maximum value. #### **(Pro feature)** Optimized Shader Stripping These are per-material shader stripping flags to improve Unity's shader stripping process to further reduce the size and memory of the shader. Read more in the [Optimization Tips](/documentation/optimization-tips). #### **(Pro feature)** Custom Fallback Shader On older OpenGL ES 2 devices, the shader falls back to a custom reduced set of features designed to preserve the original look. More details in [Optimization Tips](/documentation/optimization-tips). ### Other #### Animating Textures Included is a *OmniShadeAnimateTexture* component which can be used for easily animating the movement of any texture in the shader. Animation type can be either slide or ping-pong. **Extendable Shader UI** OmniShade has a slick collapsable UI. But, we in the field also know complexity is death. In real use, modifications and extensions are inevitable. That's why we follow a KISS principle with the shader UI. All the UI is auto-generated from the shader information, no need to fiddle with C#. And if you wish to extend your own feature in a collapsable group, simply use our custom **HeaderGroup** attribute. That's it. # Compatibility #### Unity Version **Unity 2020** through **Unity 6** #### Render Pipeline Compatibility Built-in, Universal Render Pipeline #### Additional Information * Requires **OpenGL ES 3.0** for full functionality (equivalent of iPhone 5s and above).

Set the **Lightmap Modes** and **Fog Modes** to only what you need. For example, if you do not use exponential fog or baked lighting, removing them will reduce the shader size. This can have a big impact on larger projects, so be sure to do this! * In the shader file, you can remove lines starting with `#pragma multi_compile` on shader features your project doesn't need to reduce the generated variants, which significantly reduces build time and variants. For example, `_SCREEN_SPACE_OCCLUSION` , `_LIGHT_COOKIES` , or `_LIGHT_LAYERS` , `_SHADOWS_SOFT` and so on, see [Unity shader stripping](https://docs.unity3d.com/6000.0/Documentation/Manual/urp/shader-stripping.html). * **(Pro feature)**** Shader Stripping flags** are available on a per-material basis. This is an advanced feature for larger projects I recommend touching only if you know what you are doing. It provides hints to the shader stripping process during the build process to optimize the build size and memory of the shader. For example, if you have Fog enabled on a project-wide setting, but then know that fog is not needed on a certain material, you can select Fog Disabled and the fog variants for that material will not be generated. If an incompatible setting is detected, an error color will be output. It's a good idea to make an actual build to verify the results when using these stripping flags, as they only work on builds. That said, on a major project, these flags can help squeeze every ounce of performance. * If your game is running slowly, the first thing to try is disabling some of the features. OmniShade is fast, but in the sense that it calculates only the minimal it ever needs. If you enable too many effects, it will slow down. Also, some features are enabled by default for general usage, but every enabled feature costs a little performance so disable what you don't need. * On lower end devices, using many textures and layers, or the contrast settings can impact performance. It is worth considering whether it's possible to pre-flatten the effects into fewer textures, rather than blending them in real-time in the shader. * **(Pro feature)** On OpenGL ES 2 devices, such as iPhone 5 and below, the shader falls back to a minimal subset of features, intended to preserve the original look. You can toggle this from **Menu->Tools->OmniShade->Switch To Fallback**. \ If want to control this from code, you can call *OmniShade.SetNormalShader()* or *OmniShade.SetFallbackShader()*. And if you are a little shader-savvy, you can tweak the features enabled/disabled in the fallback shader by adjusting the shader keywords. The main limitation for OmniShade with GL ES2 is 8 interpolators (up to TEXCOORD7). * If your project has no need to support OpenGL ES 2, you can completely remove the Fallback subshader section in the shader file to reduce the memory size. * Finally, general Unity [drawcall batching tips](https://docs.unity3d.com/Manual/optimizing-draw-calls.html) are always good to review. # FAQ #### What is the difference between OmniShade and OmniShade PBR? The main difference is that **OmniShade PBR** uses physically accurate lighting and was built using [Shader Graph](https://docs.unity3d.com/Manual/shader-graph.html), while [**OmniShade**](https://www.omnishade.io/) offers more stylized lighting and was hand-coded from the ground up. They share some features, but differ greatly in the lighting quality, performance, and implementation. The **non-PBR** **version** is far faster in raw performance as it was written from the ground up to ensure performance on mobile platforms. As such, it is more limited in its integration with Unity lighting features, and the non-PBR results can end up looking cartoony rather than realistic. It is also able to offer more features, customization and performance through its code-based implementation. The **PBR version** on the other hand, as an extension of the [Standard Shader](https://docs.unity3d.com/Manual/shader-StandardShader.html), is fully integrated with all of Unity's lighting features and pipelines. With a physically based model, the material can be tuned once and look realistic in any lighting condition. And since it was built using Shader Graph, even non-coders will be able to understand and make modifications. In short, if you are developing for mobile or not creating a PBR-looking game, then the non-PBR version will likely suit you more. If you've already been using the Standard Lit shader, then the PBR version will be a straight-forward upgrade. Of course, you can also always use both in a URP project as well. #### Why offer a non-Pro and Pro version, and what is the difference? For most hobbyists and indie developers, the non-Pro version is likely all you need. But, if you love the product and would like to support the developer (me), I do offer you that opportunity with the Pro version. In exchange for a donation, you get a few optimizations on build size and memory, a custom fallback shader for OpenGL ES 2 devices, and a very cool [triplanar mapping shader](https://www.youtube.com/watch?v=U_K1lnhjlFI). Rest assured, you're not missing out on much if you never go pro. But if you hit it out of the park with your game, come back and support us with the Pro version. #### What are MatCaps and why should I care? [MatCaps ](https://www.youtube.com/watch?v=qPVUW1tFT-0)are popular in 3D sculpting, and are able to capture an entire environment's lighting, including all global illumination and reflections, in one texture. More over, it is very good in performance, allowing realtime rendering of lighting and effects that would otherwise be impossible on mobile devices. \ The only short-coming is the lighting is captured from a single angle, so even if you rotate the camera, it is as if the object were rotating in a static-lit environment instead. However, in many games this is not particularly noticeable nor a problem. You can [download ](https://pixologic.com/zbrush/downloadcenter/library/)more MatCaps online, and import them for use in OmniShade. #### Spot lights aren't working? Spot lights are supported only on URP. For Built-In Pipeline, you can use a [Projector](https://docs.unity3d.com/Manual/class-Projector.html) to achieve nearly the same effect as the spot light. The reason for this is due to the limitations of the built-in pipeline with stylized custom shaders. Another technique may be to apply 2 materials to the same object, one with OmniShade and one with Standard shader for the spotlight lighting, although this requires the object to be rendered twice. #### Can I do vertex color and texture painting with a tool like Polybrush? Yes, you can! Learn how to [paint textures](https://www.youtube.com/watch?v=PgEv3Au6X08) using the layers. Note, the latest version (1.1.6) of Polybrush may have bugs painting meshes (particularly on URP), so I recommend downgrading to 1.0.2 if you experience any issues. #### What is triplanar projection mapping? [Triplanar mapping](https://www.youtube.com/watch?v=U_K1lnhjlFI) projects a texture from all 3 axises onto the mesh, relying on no UV coordinates. This is particularly useful for 1) procedural geometry, where you cannot generate good-looking UVs 2) heightfield terrains, which have stretched UVs and would result in stretched textures, 3) modular environments, which are composed of smaller pieces but need to have an integrated look, or 4) some complex geometry you are too lazy to UV-map. It also supports a top-side texture, so you can have snow/grass covering effect. There are many interesting uses that can get you out of a texturing jam, I encourage you to experiment with it! #### Objects are not rendered in the right order, or disappearing behind others. This is due to the culling and depth settings. There are Presets in the shader at the bottom, including: Opaque, Transparent, Additive, Transparent Additive, Opaque Cutout. For example, transparent objects need to have Z-Write disabled and Render Queue at 3000 or higher. #### How can I modify the material at runtime? Material variants are determined automatically at buildtime based on what features are enabled or disabled on the materials. So if you are modifying a material's properties at runtime, be sure to use a non-default value for the property to ensure that it is enabled. For example, if you are slotting in a texture by code, ensure that feature is enabled by slotting in a white texture into the material. #### Are GPU Resident Drawers supported? [GPU Resident Drawers](https://docs.unity3d.com/6000.0/Documentation/Manual/urp/gpu-resident-drawer.html) from Unity 6 can be easily configured, however it is not supported out of the box as it increases shader requirements from OpenGL ES 3.0 to 3.1. To set it up, make the following changes: 1. Change the `#pragma target 3.5` line to `#pragma target 4.5` in the URP shader file. Do this for each occurrence. 2. Add `#pragma multi_compile DOTS_INSTANCING_ON` to each shader pass. Also ensure [GPU Resident Drawers is enabled](https://docs.unity3d.com/6000.0/Documentation/Manual/urp/gpu-resident-drawer.html). #### Is this supported on OpenGL ES 2 devices? On OpenGL ES 2 devices like iPhone 5 and lower, the shader falls back to a stripped down version of the features, designed to preserve the original look **(pro feature)**. For non-pro, it fallback to the Unity Diffuse shader. See the [Optimization Tips](/documentation/optimization-tips) for more info. #### The point lights are popping in and out, is this a bug? This is a known issue with custom shaders on the built-in render pipeline, and occurs when you have a directional light and 2 or more point lights. The fix is to simply set the directional light's **Render Mode** to **Important** instead of **Auto**. #### Materials appear to have flickering artifiacts? In older versions, the Culling And Depth Preset for Opaque objects was improperly configured, which caused flickering on URP, particularly with HDR enabled. You can fix the flickering by setting the SourceBlend to One, and DestBlend to Zero on opaque materials. #### Why is the shader hogging so much memory? Be sure to read the [Optimization Tips](/documentation/optimization-tips) section to ensure your project is configured optimally. #### Can I use this shader in my commercial game? Absolutely!\ No attribution is required, although appreciated. # Videos #### [OmniShade YouTube channel](https://www.youtube.com/channel/UC9zwQIusdd2nU9A6jm2Z3Zw) {% embed url="" %} {% embed url="" %} {% embed url="" %} {% embed url="" %} {% embed url="" %} {% embed url="" %} {% embed url="" %} # Images ![](/files/4YZ4kFXDesgjiPkh6PK0) ![](/files/Que8eDQ2DNQUjA3t3UI3) ![](/files/yrTZwOglJNsQeMAH7HPX) ![](/files/NNH3dzSyhYv5eA8NfSv5) ![](/files/ofExXegKxlbn5BUvStUH) ![](/files/R6S0cVR05l5Zd4sDrQde) ![](/files/KMVRSgciRZIG39E7Vvle) ![](/files/rCL5c005e7mFCCNEOWQc) ![](/files/gUhVRgd82aIkbwhmSmzR) ![](/files/8V73iBJtMA2fgvBYsu42) ![](/files/TNAEbpUmgCbJP2kGVzPj) ![](/files/kmLMitNmq1CSyiybbbX7) ![](/files/CwHiJM1awB9xDc7p1bJU) ![](/files/NY6q28X6ot0Iy4Zj3Vbf) ![](/files/8lTWyU4k0qdm4lqByC5E) ![](/files/E5gnfm0B129fpsNfxZLZ) ![](/files/ptN1Aknq9BMoGYGniaTU) ![](/files/O3EyBXBeQZhDODEm2pf8) ![](/files/kEjNpBDSAkXnoU5bToaj) ![](/files/0IFRcyciGOow3cOlBhFl) ![](/files/ByMzENtvodcTjSnAMHSE) ![](/files/YwYNwPLrOmlIObSbNvmU) ![](/files/VyuF2vnpO96XxQA32S82) # Playable Demo Simple demo which demonstrates a variety of the shader's capabilities.
