Imaginate, that you have done the most beautiful and nice 3d model ever and textured it and made nice renders of it and everything. Yeah, your model is not ready yet. You just can not use it in animation without the setup that makes it more easy to animate. Of course you can try to animate all the vertices by single, but the result looks like a type of shit and you will waste rest of your life with it.
So by doing the control system for the model we will avoid that kind of frustration. In nut shell: rig is the system for animating the 3D-model.
In my caption I told that I have been scared for the rigging works and I can tell that I still do not love it even thought I have started for learning it. Modeling the 3D-models is pretty easy, you can learn to make simple 3d-models in really short time. But rigging is much harder because as a 3D model you can just watch a picture and copy the details to your 3d-model. In the rig you can not do that. There is too much of invisible functions in that system that you just neet to know exactly what to do if you want to make a complite working rig to your character.
I started this journey with doing mechanical rigging tutorial. Here it is.
So I just made same kind of robot that he also has made and then started following the tutorial.
Here is the picture of my robot and its rig:
|Now with the control bones (the sticks) I can control the animation of this object.|
Update: I did ask on the blenderartists.org forum about this rigging problem and few really nice guys did help me for doing it better.
So I started to model some really bad looking car, just only to make it to be a rigged model.
Yet I can not turn the front feels in that car, but i am trying to understand how to make it working correctly. Because of that kind of problems, i have been scared for starting to learn the rigging. But now I have started it, here I come!
