For my office scene i have created a modular ceiling, like you see in most offices.
I got sections with 1 tile but also 2x4 8x8 1x4 ect. so i can place indented details in there later down the line.
However after baking the scene i noticed that it doesn’t seem to blend the lighting well from one mesh to another.
notice how the brightness jumps from one mesh to its neighboring mesh.
