I have a static mesh that has an emissive material applied to part of the mesh. The emissive material successfully cast light to surrounding objects. However, the face of the mesh with the emissive material fails to cast light on the rest of the mesh.
The parts circled blue has the emissive material, and the sphere and cube are both lit by the emissive material. However, the part of the stairs (highlighted in red) does not get lit.
Is there a way for the stairs to be lit by itself?
