ERROR: Failed to compile pixel shader?

Hello

What would cause? I’m trying to isolate a weird problem that occurs in the editor. I’m making. Any clue is appreciated?

This happens when a ShaderVariation is created for a Shader that doesn’t exist.

Not 100% sure how this would happen in practice outside of accidentally passing a null Shader when creating a ShaderVariation in code.
