Lightning bug on hammer - anyone can help?

[Gabriel Henrique]

Hello, this is a map I'm working on, and I'm facing some annoying lightning issues and here they are. 

Those black shadows on the displacement. The thing is: if destroy the displacement, this bug does not happen, but I want it to be a displacement.

And yes, I have nodraw brushes behind and under all the displacements.

Please, can someone help me out fixing this?

Hi Gabriel,

Does your displacement brush face extend below the ground? Often when the ground faces a lot of a brush, it will mess up the lighting.

Best case is an L shape where the ground and the wall begin at the same point.

In this case I think it's that the displacement is too wide with too large lightmaps. Try cutting it once in the middle, if that's not enough, lower the lightmaps to 8.

I tried both and it worked very well. Thanks everyone!
