    Every time I close down hammer and start it again, or when compiling, a certain vertex edited brush always edits itself, moving one of the nodes a few units y-ward. Anyone had this problem, and how do I fix it? The brush isn't particularly complex, but the brush is always edited in the same way each time I compile the map.

    just to make sure, you DO save before closing, correct?

    Couple things you may want to try:

    1) delete the brush completely and re-add it back in
    2) make sure the brush is not acute in anyway if you are manipulating the vetex, this will cause major issues when compiling or saving and re-loading
    3) post a screenshot of the brush before saving and after saving so we can see what is actually happening. :)

    You should also make sure the brush isn't an invalid solid. For example, if there's a four-sided face, you can't put its corners just any-old-where.

    EDIT: Actually, upon rereading your post, I'm almost positive that's what it is. One of those corners isn't concurrent with the other three on one side, so Hammer is trying to fix it so that it is. Are you trying to make one of those spiral ramps, perchance? That's what caused it for me, and the trick is to slice the pieces in half diagonally so you have two valid wedges instead of one invalid angled trapezoid.

    The corners were quite logically placed, but making it two wedges fixed the issue.

    Hammer only calculates coordinates to a certain number of decimal places, so if vertices are off the grid by a very small amount, they will be rounded and moved.

    That too. Pity there isn't a "here, take these two points and make a new vertex between them splitting the face without splitting the whole brush" button in Hammer. I'm sure the real 3D modeling tools have one.
