And Blender is difficult to get running, it requiring following a long series of complex instructions made to be as vague as possible.
You must install Python. No, not the most recent version. It doesn't work with that. You have to find an old version. Now, you have to build some stuff. We won't tell you how to do that, you'll just have to figure it out yourself. Now, to set up Blender, go through these complicated steps. You will get one error after another, and have to join the thousands of others that post on the Blender forum asking how to get it to work, just so some long time forumers there can give you the same vague instructions or link you to an old post with a few thousand pages of information to sort through. Yes, they are the most sadistic people on Earth, obviously, who get their thrills causing you endless frustration.
Thats my experience anyway. Tried to get the scripts working to load .obj files properly, and got nothing but stress.
