    The first: This is the semi bit - What is the default size for cubemaps? I've found a new setting that lets you make them any power of 2 untill 256 - which I thought was the default.... but OMG it makes such a nice finish!!!! (see pic)


    The second: this is the advanced one - How do i find those damn degenerate faces? Interlopers says that they aren't a problem and to ignore them, but I don't want to ignore them! I want them gone so that my map is 'error free'

    .. extra material..

    So uh whats the deal then? I have to assume the 256 is more grahpic intensive? And if so how much more so?

    If 32x32 is normal I would imagine bumping all cubemap sizes up to 256 would be far mroe graphicly intense, I do not intent do do this, 32x32 is fine for almost all cubemaps, but now I've seen the 256 ones I will be using those for the control point cubemaps and only the control point cubemaps.

    32x32 = 1,024

    256x256 = 65,536

    So using a larger values causes each cubemap to take up to 64 times the texture memory -- and filesize in your map.

    Ok, so does no one know a way of finding degenerate faces?

    what is a degenerate face?

    Is it an error showing up in the check for errors dialog? Because usually if you just double click on the error it will show you where it is.

    No they don't show up on the check for errors thing in hammer, they come up in the compile log. They don't actualyl cause any problems, what they are:
    You're editing a brush in the vertex maniplulation tool, you drag two coners together to make the once cubeoid brush a triangular prism and you accidentaly say no to "merge these two verticies" They you have a face which has a surface area of 0 and you are unable to remove it without clipping that part of the brush off (afaik)
