I am trying to setup Office ceiling lighting ([example]). I guess that’s have something to do with materials + lights.
Tossing Emissive material on mesh gives nice glowing but contribution in overall lighting of scene in zero
Any suggestions and samples would be much appreciated
Its actually a new feature that appears in 4.6.
its still sort of a work in progress, but its getting there.
“Turn this on using the new “Use Emissive For Static Lighting” option on shadow-casting components with Mobility set to “Static”. When enabled, Lightmass generates baked direct lighting from emissive texture sources.
Note: this is a fast but limited version of emissive lighting. Only direct lighting is computed but build time is not affected. It is best used in scenes that have other light sources.”
