What exactly causes these glitches? (pics)

[BirdsofaFeather]

It seems that every time I make a new map, I eventually get these glitches somehow in an unexplained way. They always seem to be eminating from textures, as is the case here. However, in my last map, all I did was change the textures and the glitches went away, but here I tried that and it didn't work. It's not the actual texture because I have the same textures elsewhere in the map. Anybody know what causes this to happen?





I'm sure somebody's had this problem before and it's probably easy to fix, I just never had to because changing the texture worked last time. Thanks in advance.

That looks like a MAX_POINTS_ON_WINDING error.
It is caused when too many brushes contact one brush, exceeding the vertex-per-face count allowed.

The floor brush(es) contacting your small wall pieces need to be divided into sections, 3 or 4 should do it, so that only 1/4 to 1/3 of those wall pieces contact any one floor brush.

EDIT: On taking a second look, it appears those sections are contacting the wall itself, so divide the large wall brushes into smaller pieces.

oh, well that's probably why my smaller brush sections don't have that problem, wow, don't know why I didn't see the connection. Thank you.

I use to get a lot of that to. I connected my 'problems' like this to the many 'untextured' brushes i had. On all of my beginner first maps i never used the caulk texture so i had loads of untextured brushes. I compiled and tested and id get these glitches... id go back and find all the untextured and change them to caulk, compile, test... and they were gone. Could have been coincidence but .... worked for me, i guess.

Happens a lot when people make ladders as well . Too many rungs touching the rails .

Or you dont put the texture on the ladder before you make it a ladder (with the ladder brush and the angle stuff)
