Many MANY updates since the last post.
Now there is really no limit to exporting 3ds Max scenes into the Source game engine. With Wall Worm, you can export World Geometry, Displacements, Models, lights, entities, entity scripting, materials, textures, 3d skies, 2d skies and more.
You can also import VMF, MAP, VMT, SMD and VBSP files into 3ds Max with Wall Worm now.
Thanks to Robert Briscoe and Dear Esther for funding some of the latest enhancements including the VMF and VBSP importers.
