The lightmap resolution on each wall is 2048. I'm not using ambient occlusion. The render is in preview quality, but the black or obscure areas also are there when I set production quality.
You can see my spotlight setting.
I tried with LPV Bias Multiplier on walls... but it not works.
I left enough space on the sides of the UV channel 2.
Any idea? thank you.
