    this happened when I selected all the snow brushes and used the paint geometry to add those little mountains (if you can call it that) at the edges of the map as seen in the picture.

    It's because you turned the entire brush into a displacement, and the hidden faces beneath the top surface are confusing the lighting process. When you have the face edit tool open, be sure to select only the faces you want to displace before hitting "Create". You can delete displacement faces after the fact with the "Destroy" button.

    That's caused by you making all the faces of a brush a displacement. Only select the face of a brush that you actually want to displace when you create a displacement.

    What you can do now is select all the displacements, deselect the top faces then hit "Destroy" so that only the top face of a displacement is a displacement.

    So I tried it only selecting the top faces, however I now get those ugly gaps between brushes (I tried using autosew and even sewing afterwards. But no changes were made.)

    Then your displacements must not be sewable. They have to follow specific rules to be able to sew with one another - see this section of the VDC wiki page.

    Judging from the first screenshot, your displacement faces are a lot bigger than they should be, and could use some cleaning up. I recommend creating your ground as a grid of 512x512 (or smaller) brushes, with a power of 2 or 3 depending on the resolution you need. This will ensure that the displacements all sew with each other, and gives you room to break up your flat ground with ramps, cliff walls, or raised sections.

    you mean making brushes that are 512x512? Because then they won't exactly fit.

    Yeah, something like that, but you can go smaller or make rectangles if you have to. It's only a suggestion, but I'd say it's good practice to have a neat grid of smaller ground brushes instead of a few big ones for the reasons in my last post.

    Make sure you turn off "fast" under VRAD in the compile settings.

    That's a good way to put it :p

    I mean yeah, that's another cause of this problem, but I made a guess based on the wording of the guy's original question and his response suggests I was right.

    Just asking before I do something the wrong way;
    those 1024x1024 brushes do not fit this way: [​IMG]
    does that mean i have to use like 512x512 brushes? And if that doesn't work use 256x256 brushes?

    Only the edges have to line up. You can use a 1024 x anything brush, as long as the edges next to each other are the same length.

    Ah, sorry, I didn't mean to imply that you can only use certain brush sizes - the 512x512 was more of a size guideline (i.e. try not to go bigger). The idea is that you make your ground out of smaller brushes with their edges aligned so that they remain sewable. They can be weird sizes, rectangles, whatever. As long as it's like a patchwork quilt, you can more easily do interesting stuff with your ground.
