I cannot get an emissive texture map to cast light. Pulling hair out

Hey there. So I’m brand new to UE4, so let’s keep that in mind. I might be missing something very simple, but I’ve tried to eliminate everything I’ve found online already about the issue I’m experiencing.

1. I built a model and made a reasonable texture UV in MAX.

2. Pulled into UE4. Built all the lighting, model looks fine. Lightmaps look fine.

3. Added a simple emissive map, and the areas successfully started glowing (see image).

4. Set up “Use Emissive For Static Lighting” (see image), and bumped up the boost to try and see any change (none).

5. Double checked I’m using the right lightmap channel.

6. Emissive just won’t cast light.

Anyone have any ideas at all? I’ve tried in a blueprint project, and in a blank one. No difference. I’ve just done a full emissive material on an object as a whole, and it works as expected (glows and casts light). But as part of a texture map, I just can’t get it to work.

Haaaaaalp. Thanks in advance.
