there an example file for the lightlayer3d effect here https://kindeyegames.itch.io/c3-3dobject-alpha/devlog/324554/light-layer-3d-effe... but I can't download it. Please add a download so I can figure out how the effect works.
I'll look for that older file, in the meanwhile, this example also uses the effect:
FighterPerfLayerLight3D.c3p
