I have a significant update to Wall Worm coming soon. I was hired by Robert Briscoe of Dear Esther (http://www.littlelostpoly.co.uk) to update and finish the VMF Importer. So that will be out as soon as I test some of the features that I've changed that may affect how WWMT works and the SMD Exporter. Premium Members can get a preview of the upcoming release from the links here (http://www.wallworm.net/index.php/topic,616.0.html).
This is a very large release that makes the VMF importer (VMF > 3ds Max ) correctly bring in all geometry, UVW and even prop meshes! I need to document a couple of the VMF Importer features ... so please be patient with me if you don't understand immediately how to get all props and materials to import with a scene. Special thanks to my friend Andrew Penry (http://www.andrewpenry.com) for helping me solve the importing of VMF face UVWs into 3ds Max coordinates.
Other updates include some really cool enhancements to how displacements work, enhancements to the SMD/QC importers, speed enhancements to entities and some bug fixes. I'll give the changelog when I actually release it.
