When I "run map" with normal options, the output box tells me about areaportal errors that have occurred, and which brush caused it. However, I can't seem to find a flag to enable this output from VBSP in the advanced/expert window, and I'd like to have this info along with some other parameter flags I've been testing out. I checked the parameter list for VBSP and VVIS, but the output I'm looking for is actually coming from VBSP, and takes the form of "Brush 572915: areaportal brush doesn't touch two areas." I'm basically trying to achieve the same compile settings and output in expert mode that I get using the "normal" menu. Any ideas?
