Hi rick0! Sorry the late on the answer!
At the moment this is only partially possible.
Right now, the pipeline does have some UI-specific handling, but it does not yet support a full separate UI rendering path with its own volume profile, and it also cannot completely exclude a Canvas from all pipeline effects in a general way.
What is possible today is:
- UI can be rendered in a separate UI stage inside the pipeline
- there are settings that help with UI readability/clipping for World Space and Screen Space - Camera canvases
- motion blur can already be configured to affect or ignore UI overlay rendering
If that is something you need, I will implement a dedicated option to enable/disable the pipeline effects for UI/Canvas rendering specifically. If you want, I can also make that configurable per camera or per canvas depending on your use case.
