layered material revealed by light source?


Is it possible to have a material that when unlit displays material A and when it’s being lit by a light source it reveals material B on the lit parts?


Hey Beddall -

Not directly, without forward rendering, we cannot call the lighting information into a material. You could use a scalar material parameter and a predefined mask, to LERP between two material setups based on the forward vector of a particular light source which is set up and called in a blueprint.
