Hi all. I’ve jsut dug this out and managed to get it working in UE5. Needed a tiny bit more work than before but its all behaving nicely. As far as I can tell, when I write into the customData channel of the GBuffer, then that automatically gets written to the subsurface color. What I can do though is write to the PostProcess 5 as well though, so technically its duplicated. Maybe there’s a way to create another output for the GBuffer and reroute it to the PP5/PP6 but thats not something I’ll probably do right away.
