    Hmm, I seem to be doing something wrong with my brushes that I have above stairs, they almost always end up with hideous shadows. Any ideas whats the deal?

    There aren't any leaks. Do I just need to stick a light in all these spots?

    Heres a screenie. :)

    are you sure that brush doesnt continue along the wall?
    btw, check the lightmap setting

    Also check if the alignment is set to world or face while the walls are set to the opposite. Sometimes that affects lighting. That's kind of what it looks like it does when that happens in fact.

    You can try setting it to the same smoothing group as the walls if the above doesn't work.

    Nah, it didn't go inside of any other brushes, and I haven't touched the Lightmap setting just yet.


    The alignments seemed to just push the shadow around the face (unless the shadow is random each compile)


    The smoothing groups was the win. I set all of the same brushes (including ones in different areas) to a hard smoothing group, and now they're all good. Are there any downsides to using them? :)


    Cheers. :)

    They only affect how the lightmaps are formed, unless you have some dynamic lighting (and really, in TF2, who does?), so no. In my experience you can also reuse the same smoothing groups elsewhere in the map, so you're not in danger of running out of them either.

    Could be related to light bounces

    Try compiling with -final and see if that fixes it.

    I've always found that you can fix this just by better light placement. Here, you could just include another light and this shouldn't be a problem.

    Really i think that'd look almost okay! :O

    Well anyway your best bet'd probabaly be to add another light near it or disable shadows on the light making this shadow.
