I'm going to list a couple of websites where you can find free character or stage 3D models so you can use the for EF-12.
If you know more or better websites, please post below and I will update this first post.
MikuMikuDance is another good resource. Mostly for animations, but can be used for other things.
Which extension for animation does MMD use?
MMD uses vmd files for motion and animation.
Finally found time to get into it, fun.
For anyone interested, here's a basic jump animation tutorial.
Lesson can be applied for models outside of MMD.
Have a feeling that I'll be multi-posting a lot.
Well, today we’re going to learn how to fix this problem, or at least start learning how! My name is Stella, and I am an ambitious (Sometimes a bit too ambitious) MMD modeler, with experience in all aspects of PMD Editor. I’m going to teach you the basics, starting with the interface. I’ll even teach you how to make your very first model - and use it!
Just learned about Pmx editor. It allows one to edit and create models for MMD, which is surprisingly easy once the interface is learned.
Been tinkering with models for the past few days.
http://www.cadnav.com/ is missing from the list has a good selection of game characters http://www.cadnav.com/3d/Street-Fighter.html for example.
