Hi,

Is it possible to do a projected texture or mask a spotlight so only a pattern of light is projected onto other surfaces?

I’m trying to create a disco ball effect. My first and only idea was making a sphere with holes in it and putting a light inside it but honestly I don’t know why I ever thought that would work

May be cheaper to fake it with meshes using semitransparent materials, like fake godrays.

If you want shadow projected from inside, you may try with either flipped normals, or reverse shadow culling. I see no reason why a sphere with holes on it would not project shadow^^ maybe shadows don’t work with double-sided materials, maybe you have to choose a side.
