Seeing as I can't get 3dSimEd to do so much as create a new file, I heard that you can create animations in BTB of up to 3 frames or something. How EXACTLY would I go about doing this? For 3D modelling programs, I use SketchUp 6. I need it from start to finish - what I need to do in SketchUp once I have built a model, any special ways to Xpack it, things that need to be done in BTB etc. I don't want a solution to my problem with 3DSimEd - I have another thread with all the details, any solutions can be posted there.
