Kinda hard to explain, so here's the screenshots of it:

The first picture is an overlay placed on 3 displacements , while the second is placed on 2. The black part only consists on one brush face but the overlay on that brush face isn't fully black, it's half-black.

I tried Smoothing groups, cubemaps, cubemaps assigned on brush faces, additional lighting, but none seemed to work.

So... any help on removing the black parts? Please?

Is the origin of your world located within a brush face? I've had similar problems with brush faces appearing completely dark, and the problem was alleviated when I shifted the world so that the origin wasn't in a brush face.

The 0, 0, 0 point is far away from that brush face.

Seemed to be a problem with displacements being too long. Tried splitting them and it works.
