[SOLVED] Why I can't use custom shader with cast shadows on render component or light component?

Hi @LorRrR and welcome,

Can you elaborate on how exactly are you structuring your code and shader?

In general if you are looking to leverage lighting/shadows then you should avoid writing a custom shader but instead use shader chunks (override part of the internal PlayCanvas rendering code). Example project:

I just copied shader project files into my project, but this error appears, and disappears when I turn off cast shadow either on render component or light comp.

As I said, you can’t use a custom shaders with PlayCanvas lighting/shadows. You need to use shader chunks for that.

Thank you!
