Hi, the 2D Renderer isn’t very extensible right now. Not sure what’s possible with passes.
At worst, you may need to fork it. Forking a package takes a bit of extra work. You need to download the source code from Github and add the folders of the packages as a disk directory in the Package Manager. Then you can modify the source without it auto-reverting.
A notable example of someone who has done this is @AlexVillalba , see this thread .
