Lightmap emission with custom shaders?
I have a custom emissive shader in Unity (the shader is not deferred). When I bake lightmaps, the emissive shader does not light the surrounding environment with its emission. But when I bake using the Standard shader, it does.
How do I make the emission of a custom shader behave the same way as the Standard shader when lightmapping? I couldn't find any documentation for how to do this.
Found it. Sharing the love in case someone else has this question and finds this thread:
