CVR Blitter

Runs Unity’s Graphics.Blit with optional material overrides, automatic output clearing, and a multi-target mode that uses a GL pass with up to eight color buffers.

Fields

| Name | Type | Description | |------------------------|---------------------|-------------------------------------------------------------------------------------------| | originTexture | RenderTexture | The input texture used as the source for the blit. | | destinationTexture | RenderTexture | The output texture that receives the blit result (single-target mode). | | blitMaterial | Material | The material applied during the blit operation. | | clearEveryFrame | bool | When on, clears destinationTexture to transparent each frame before blitting. | | destinationTextures | RenderTexture[] | Multi-target mode outputs. Null entries are filtered at Start. | | _MultiTargetBlitMode | bool | Switches to the GL-based fullscreen quad blit that writes into every entry above. |

Behaviour

Single-target mode (default)

If destinationTexture is null, the blit uses the material’s implicit target (Graphics.Blit(originTexture, material)).
If source and destination point at the same texture, the blit ping-pongs through a temporary.
Otherwise the blit writes originTexture into destinationTexture through blitMaterial.

Multi-target mode

When _MultiTargetBlitMode is true, the component issues a GL pass that draws a fullscreen quad into every color buffer in destinationTextures (using the depth buffer of destinationTextures[0]). blitMaterial must be written to sample _MainTex — the component temporarily overrides that to point at originTexture during the pass.

Execution

By default, the blit runs on Camera.onPreRender for Camera.main. When a CVR Blitter Controller references this blitter, SetupBlitterForExternalControl is called so this component stops driving itself and is triggered in the controller’s order instead.
