Methods

Blit(CommandBuffer, RTHandle, RTHandle, Material, int)

Add a blit command to the context for execution. This changes the active render target in the ScriptableRenderer to destination.

Declaration
public void Blit(CommandBuffer cmd, RTHandle source, RTHandle destination, Material material = null, int passIndex = 0)
Parameters
Type Name Description
CommandBuffer cmd

Command buffer to record command for execution.
RTHandle source

Source texture or target handle to blit from.
RTHandle destination

Destination texture or target handle to blit into. This becomes the renderer active render target.
Material material

Material to use.
int passIndex

Shader pass to use. Default is 0.

Configure(CommandBuffer, RenderTextureDescriptor)

This method is called by the renderer before executing the render pass. Override this method if you need to to configure render targets and their clear state, and to create temporary render target textures. If a render pass doesn't override this method, this render pass renders to the active Camera's render target. You should never call CommandBuffer.SetRenderTarget. Instead call ConfigureTarget and ConfigureClear.

public virtual void Configure(CommandBuffer cmd, RenderTextureDescriptor cameraTextureDescriptor)
Parameters
Type Name Description
CommandBuffer cmd

CommandBuffer to enqueue rendering commands. This will be executed by the pipeline.
RenderTextureDescriptor cameraTextureDescriptor

Render texture descriptor of the camera render target.
