If you apply the cellshader as a post process, check alpha inclusion in different rendering, and render it, the black background is rendered with the same background.
If I remove and render the post-process, normally the background will only appear as objects that should be rendered in transparency, but if I apply the post-process, I will have a problem with black background.
What I’ve tried to do is to check hide actors in the game and leave only the objects that need to be rendered, rendering them in stencils
