I've been trying to learn 3d animation. I'm a software developer. I don't have a formal education in animation or about graphics. I found this tool for maya
And upon watching the tutorial on the website the tool is super cool. I've read that the blender can also do this. But the problem is I don't know how to make a model. So i will look for models online. But the problem is this. The free models i downloaded online is glued as one. They doesn't have a parts like eye, tongue, mouth, face. So i need to buy a model. But i need to know the requirements before buying a model.
How do i know that the model can blink, smile or talk?
