I have a couple of .qcs that I'd like to import with a map into Max, but the automatic quadrifying that the importer does deletes some necessary edges in the models and I can't find a way to turn it off. It doesn't seem like a problem with the models themselves, since the .smds import properly as tris. Any help would be appreciated.
That's unfortunate :)
At the moment, all staticprop models are automatically quadrified. I'll look into adding an option to disable that.
You can now do this in WW 2.725. There is an option for Auto Quadrify Staticprops in the QC options.
