I want to extrude some 3d logos, icons from the post processing volume’s default effect? like the White Balance ,Bloom?

I know i can extrude some actors from post process materials using custom depth or stencil. I’m talking the default effect in PPV.

Thanks in advance!

The only thing you can do now is to modify engine in such way that you make copy of RT before executing postprocess graph, and them at the last step of graph composition you copy portions of that copy into final result (based on you custom depth/stencil value). If you do not want to modify engine IMHO the only (but costly) solution is to render excluded object into scene capture and then compose them in postprocess material …
