| nameID | Shader property name for this texture. |
| width | Width in pixels, or -1 for "camera pixel width". |
| height | Height in pixels, or -1 for "camera pixel height". |
| depthBuffer | Depth buffer bits (0, 16 or 24). |
| filter | Texture filtering mode (default is Point). |
| format | Format of the render texture (default is ARGB32). |
| readWrite | Color space conversion mode. |
| antiAliasing | Anti-aliasing (default is no anti-aliasing). |
| enableRandomWrite | Should random-write access into the texture be enabled (default is false). |
| desc | Use this RenderTextureDescriptor for the settings when creating the temporary RenderTexture. |
| memorylessMode | Render texture memoryless mode. |
| useDynamicScale | Whether to enable DynamicResolution for the texture. |
Add a "get a temporary render texture" command.
This creates a temporary render texture with given parameters, and sets it up as a global shader property with nameID. Use Shader.PropertyToID to create the integer name.
Release the temporary render texture using ReleaseTemporaryRT, passing the same nameID. Any temporary textures that were not explicitly released will be removed after camera is done rendering, or after Graphics.ExecuteCommandBuffer is done.
After getting a temporary render texture, you can set it as active (SetRenderTarget) or blit to/from it (Blit). You do not explicitly need to preserve active render targets during command buffer execution (current render targets are saved & restored afterwards).
Additional resources: ReleaseTemporaryRT, SetRenderTarget, Blit.
