Hi, this is my problem:
Both A, and Custom nodes are CustomExpressions, I just simplified the problem from my complex shader. It seems that now I cannot parse a custom function as an input to other CustomExpression. Is there any workaround?
Untill 4.20 it was possible and was advised by Epic, here’s an example: Custom Material Node: How to use and create Metaballs | Live Training | Unreal Engine - YouTube
