I am creating a custom actor for emissive static lighting and I’m quite happy with the result. Yet, I have noticed a strange behavior: in order to have the emissive baked in the lightmass, the mesh must have static shadows on.
Is this intended?
To reproduce this just create a mesh with a strong emissive material, set it to static, turn on Emissive For Static Lighting in the mesh lightmass settings, bake, then turn off the static shadow on the mesh and bake again.
You should notice that without the static shadows the emissive is not considered by the lightmass.
