A couple of questions..

I am a 3d-modeler that uses Bryce, Carrara Pro and Hexagon. Can I create objects in these apps and get them into Worldcraft (3.5 beta I'm using) for the map I am building?

I would like to add my own sounds and textures for a unique map that I am building.. understanding the FPS/Polygons, etc issues.. how do I go about this.. do I need Wally?

Thanks!
