    I have absolutely no idea what could be causing this. I've been getting the compile error: "make_triangles:calc_triangle_representation: Cannot convert", but the compile log checker is pretty much telling me that I don't need to worry about that, especially since this visual error appeared several compiles BEFORE the log error did.

    The stairs and the metal are func_detail'd, if that's relevant. I've also tried changing the material several times, to no avail.

    Any help would be appreciated.

    My initial though was an invalid brush but then I realized you probably cloned the brush to make all three so there wouldn't have been an error just on one so then I noticed the center brush is being touched on both sides by the stairs which means it has twice as many t-junctions (and they can't be fan-tessellated so they will be water-indexed) so I believe what has happened is the face has more than the max number of junctions resulting in it becoming "broken" to fix itself which results in fracturing.

    I would suggest testing this theory by hiding one set of stairs and recompiling to see if it goes away and if it does then you need to "disconnect" the stair vertexes from the metal edge which could probably best be done by turning the metal parts into a func_lod so that they are kept separate from the detail brushes.

    That worked perfectly, thanks :)

    In the future, I shall be more careful with my stairs >.>
