Try the Amapi forum. There is a free modelling (Amapi) program link, there. Also, www.openfx.org...another good free modeller. I guess I am coming from the standpoint that, if you want to learn something, there are so many forums, here where you can pick up tips and tricks...Not to mention the great tutorials....I get motivated. I visit the forums. I look for tutorials. I read them. I learn. I thought that was how most folks did it. If I get hung up somewhere along in the learning process...then, I ask a specific question in a forum. Try Amapi. Download the free one. Do the finger exercises, and, try the forum project, as well. I think you will be glad that you did. (I just had so hoped, that not getting a real positive response...you would seek farther on your own, oh, grasshopper.) Pop...pop...pop.
