When saving a model in vrml/dfx format (NOT videoscape - Blender crashes when I try that), can I save the materials along with it ? I have seen lots of posts explaining that you can import materials with models, but I want to export them. My problem is that I want to save the model in vrml/dfx, then convert to 3ds whilst maintaining materials. When I try saving in vrml/dfx, the model looks plain white even in Blender.
Can I use models in terragen, and if so how ? I have seen (I forget where) what appeared to be an environment-mapped sphere over a nice terragen landscape. How can I do this ?
