CommandBuffer

class in UnityEngine.Rendering

Description

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.
