I built a wall:
q0_1.png
The front side of it is made from 2 faces - top with simple texture and bottom with another texture (dirty at bottom):
q0_2.png q0_3.png
So, this wall requires 2 brushes. I wanted to make same 1-brush wall; I used Vertex tool to divide one of faces without dividing others:
q0_4.png

But it didn't work, my wall became an invalod solid structure.

So, is there any possible way to apply 2 different textures on one side of brush/make 2 parallel sides without making one more brush?

I'm really sorry for my english.

You need multiple brushes. Having two co-planar faces on a brush causes issues because of how Hammer stores brush data (it just stores faces and forms edges where they intersect, meaning it can't remember the line where two coplanar faces meet).

Your English is fine, by the way.

I thought about decals and overlays. It would really be a silly solution. I better use two brushes than get at least 1 more entity per wall.
