Version 1.774 released on 4-14-2012
◦ Fixed a bug in the VMF Exporter that created duplicate geometry for all grouped brushes.
◦ Updated Texture Exporters to use $selfillummask. Previously, only $selfillumtexture was used--but that setting only works in some flavors of Source. Now $selfillummask and $selfillumtexture are used simultaneously, and the appropriate one should be used in your engine (and the incorrect one will be ignored).
◦ Added some more information to the hull functions that fail when using some installations of MassFX/PhysX.
◦ Added Quick Hulls button to Hull Helper floater. This function will create hulls for all selected WWMT helpers (useful to make a bunch of hulls for a bunch of models all at once). The hulls are created and assigned to their WWMT helper--and each WWMT that has more than one hull piece will get the $concave setting.
