List of graphics commands to execute.

Command buffers hold list of rendering commands ("set render target, draw mesh, ..."). They can be set to execute at various points during camera rendering (see Camera.AddCommandBuffer), light rendering (see Light.AddCommandBuffer) or be executed immediately (see Graphics.ExecuteCommandBuffer).

Typically they would be used to extend Unity's rendering pipeline in some custom ways. For example, you could render some additional objects into deferred rendering g-buffer after all regular objects are done, or do custom processing of light shadow maps. See command buffers overview page for more details.

Command buffers can be created and then executed many times if needed.

Public Methods

BeginSampleAdds a command to begin profile sampling.
BlitAdd a "blit into a render texture" command.
ClearClear all commands in the buffer.
ClearRandomWriteTargetsClear random write targets for Shader Model 4.5 level pixel shaders.
ClearRenderTargetAdds a "clear render target" command.
CopyCounterValueAdds a command to copy ComputeBuffer counter value.
CopyTextureAdds a command to copy a texture into another texture.
DisableShaderKeywordAdds a command to disable global shader keyword.
DispatchComputeAdd a command to execute a ComputeShader.
DrawMeshAdd a "draw mesh" command.
DrawMeshInstancedAdd a "draw mesh with instancing" command.The command will not immediately fail and throw an exception if Material.enableInstancing is false, but it will log an error and skips rendering each time the command is being executed if such a condition is detected.InvalidOperationException will be thrown if the current platform doesn't support this API (i.e. if GPU instancing is not available). See SystemInfo.supportsInstancing.
DrawMeshInstancedIndirectAdd a "draw mesh with indirect instancing" command.
DrawProceduralAdd a "draw procedural geometry" command.
DrawProceduralIndirectAdd a "draw procedural geometry" command.
