Hi. I tried searching for this problem using "vertex", which I was quite sure would find it, but found nothing.

Anyway, a run down of the problem: when I try to manipulate vertices, it creates some polygons, much like on MS paint, (you know, where you use the polygon tool to click about the place, and it joins things up and fills in the gaps).

I wonder if this might help: http://img116.exs.cx/my.php?loc=img116&image=snarkpitquestion5vr.jpg

I'm sure I didn't get this problem with worldcraft. Any advice on how to stop it doing this would be much appreciated. I hope it's not something incredibly simple that I've overlooked, my being an incredibly simple person.

You can't use vertex manipulation to make that shape of brush (or any other method, in fact). Brushes have to be convex; you can't have any indentations like that. You'll have to make your shape out of two touching brushes, say a rectangular slab and a triangular prism.

I'm not sure I understand. What I was trying to make there was this shape, which has worked here:

Oo.... now there's a funny thing: I just tried to edit again, and this time it did get the problem. (I've tried it again a few times, and it does work, but seems to go all funny when it chooses to.)


Like the avatar, by the way.

Although you can sometimes convince Hammer to make a non-convex brush, you'll usually find that saving and reloading the map will destroy or corrupt those brushes, and for sure when you compile the map you'll have major problems.

For your shape you need two brushes. It's just the way the engine works, it relies on convex brushes to compile and draw them properly.

Break the brush up into two separate ones to avoid using concave shapes. [addsig]
