Hi everybody,

I came across a problem using an emissive material and don’t know what is causing it.

Below I just quickly described my workflow and added images for a better understanding.

1. I created an emissive material (see image 1)

2. I turned off “force precomputed lighting” (world setting)

3. I selected the mesh and applied the emissive material

4. After that I selected the mesh turned on “Use emissive for lighting” (details setting of the mesh)
I turned the emissive boost to 3 (see image 2)

This section should control the intensity of the emissive material rather than changing the material itself

5. then I changed my lightmass settings (see image 3)

6. I build the lighting (medium quality) and received the error message (see image 4)

I would greatly appreciate if someone could help me solving this issue.

Thank you in advance
