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.

| CreateAsyncGraphicsFence | Shortcut for calling GommandBuffer.CreateGraphicsFence with GraphicsFenceType.AsyncQueueSynchronization as the first parameter. |

| DisableScissorRect | Add a command to disable the hardware scissor rectangle. |
| DisableShaderKeyword | Adds a command to disable global shader keyword. |
| DispatchCompute | Add a command to execute a ComputeShader. |

| DrawMesh | Add a "draw mesh" command. |
| DrawMeshInstanced | Add 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. |
| DrawMeshInstancedIndirect | Add a "draw mesh with indirect instancing" command. |
| DrawMeshInstancedProcedural | Add a "draw mesh with instancing" command.Draw a mesh using Procedural Instancing. This is similar to Graphics.DrawMeshInstancedIndirect, except when the instance count is known from script, it can be supplied directly using this method, rather than via a ComputeBuffer. 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. |
