Multiple Crossing Points for Patch - Can't Clip
« on: June 25, 2015, 10:21:05 PM »
Problem
Compiling an RtCW SP map with q3m2.2.38 I get this error cropping up multiple crossing points for patch - can't clip

It happens during the initial stage of a BSP compile (once it's run thru the shaders and 'longest curve' entries). It doesn't bork out the process (and q3map2 happily continues to do the rest of the process) so I just wondered what it meant.. I'm guessing it's something to do with a weird twist in a patch mesh somewhere (due to miss-aligned control points?) that means clipping the mesh isn't completed?? [kat]

Solution
IIRC that's due to a patch cutting the surface of a fog brush more than once, because the compiler can only split the patch once. [dayve]
