Brushes cracking/splitting up. Any way to avoid?

[Boothand]

After compile, some brushes show these kind of splits, unless I remake the brushes (with the exact same structure). It sometimes happens on brushes that are split in two. The gaps don't show in the editor, on those brushes, but sometimes these gaps appear in the editor on other brushes that don't have this problem in-game. Is there any rule that makes these gaps happen, or do I just have to remake these brushes when it happens?

All I know is that brushes will crack if rotated freely. So if you haven't rotated anything, then I have no clue.

I find that moving individual vertices (via V) tends to lead to problems so I use the 3-point-clipper (X) instead.

 

Also take a look at the brush cleanup, it may or may not help.

I'm aware of some bad functionality in 1.5, so I use 1.6 for my vertex editing. It has some clunkyness though, like refusing me to move it to certain points under certain conditions, and sometimes the vertex bugs out of the triangle in some weird way, when doing some quite crazy shapes. As for the brush cleanup tool, it has helped me out solving some problems when saving and opening files between GTKradiant versions. But no invalid brushes in this case.

 

I use the clipper for simple things, but using the three-point method only occasionally for some things. It's a bit (read: very) hard to use compared to the visually aiding (and sometimes buggy it seems) vertex tool.

 

I'll just remake these brushes then.
