I'm working with the 3d Engine Truevision 3D, and I downloaded the open-source 3d animation program Blender. So here's my question. Should I teach myself how to use Blender, and make my own 3d models and animations, or should I buy the models from someone else? If so, where can I find some good model packages? If you suggest that I learn, are there any books or tutorials you suggest?
