Posting here as I’ve run out of ideas on how to fix this, there’s a map I’m working on where lighting on the meshes has got screwed up. (see image)
All the lightmpas are set up right (UVs snapped to the grid at the edges), the meshes are just planes, changing the lightmap resolution doesn’t change anything other than the build time. I’m using a Stationary Directional light in order to the get the room lit up, using a dynamic light fixes the issues but most of the room is dark. I’ve noticed that only the meshed affected by indirect lighting are causing the problem.
The top image shows the ceiling tiles and the some of the floor tiles being affected, as well as light highlights on some of the meshes.
The bottom image shows the floor tiles being affected by direct and indirect lighting
Oh and I’m using 4.1
I would appreciate any help in this, and if you need more information, I’ll provide what I can.
