Use the Unity low-level shaderA program that runs on the GPU. More info
See in Glossary compiler APIs to inject different variants into a shader. This is an event-driven approach in which the plug-inA set of code created outside of Unity that creates functionality in Unity. There are two kinds of plug-ins you can use in Unity: Managed plug-ins (managed .NET assemblies created with tools like Visual Studio) and Native plug-ins (platform-specific native code libraries). More info
See in Glossary receives callbacks when certain built-in events happen.
The shader compiler access extension definition exposed by Unity is to be found in IUnityShaderCompilerAccess.h header file, located in the PluginAPI folder.
Note: These extensions are currently supported only on D3D11. IUnityShaderCompilerAccess.h can only compile as C++. Attempting to compile it as C produces an error.
To use the rendering extension, plug-ins must export UnityShaderCompilerExtEvent. For more information on implementing the API, refer to the code comments in the IUnityShaderCompilerAccess.h header file.
A plug-in receives a callback via UnityShaderCompilerExtEvent whenever Unity triggers one of the built-in events. The callbacks can also be added to CommandBuffers via CommandBuffer.IssuePluginEventAndData or CommandBuffer.IssuePluginCustomBlit commands from scriptsA piece of code that allows you to create your own Components, trigger game events, modify Component properties over time and respond to user input in any way you like. More info
See in Glossary.
In addition to the basic script interface, native plug-insA platform-specific native code library that is created outside of Unity for use in Unity. Allows you can access features like OS calls and third-party code libraries that would otherwise not be available to Unity. More info
See in Glossary in Unity can receive callbacks when certain events happen. This is mostly used to implement low-level rendering in your plug-in and enable it to work with Unity’s multithreaded rendering.
Unity provides the (IUnityShaderCompilerExtPluginConfigure) interface for configuring shader compiler access. A plug-in can use this interface to reserve its own keyword(s) and configure shader program and GPU program compiler masks. This determines which shader types or GPU programs to invoke the plug-in for.
