Just about ANY 3D editor I've found comes with a walk through/tutorial. If it doesn't come with the program, it's probably on the website you got it from. How you use a 3D editor is based on what the program is designed. I started my 3D editing with anim8. www.anim8or.com It is a free 3D eidtor. The problem I found with it is you can't do any animating that can be used with blitz! But if you ever got board one day you could still make animation and scenes and stuff with it. Besides, it can export as .3DS which can be used as a mesh in blitz.
