Hey folks, so Im working on a project that has alot of emissive surfaces but I end up with alot of noise in the render. Ive seen posts with suggestions on how to fix from years ago but nothing current. Ive tried what was suggested in those posts and it hasnt solved the problem for me. It feels like either Im missing something basic or something is broken
So Ive turned off all the other lights to show the problem (indirect from regular lights is fine, I dont get the noise from them, just from the emissive) So there is one object with emissive texture lighting this area. The sidewalk texture is seamless normally but you can see the seams from each piece and the road is just a plane with a texture so the lightmap is a full square and is set to 1k lightmap. Based on previous posts I changed the lightmass settings as shown. Any ideas whats causing this ? I can get around it by using regular lights but it would be nice if the emissive worked.
