Bones messes up my model? I just made a 3D model of a humanoid Darkrai from Pokémon, just for fun, and I wanted to make a little animation with it.

So what I did was;

I made the half of the model and applied the mirror modifier to create the other half.
Everything went well, untill I added the bones to it + with automatic weights.
It just completely messed up the model and I'm quite sad about it.

I'm only a student so I don't know all tricks.
I hope someone can help me!!
I think your problem is that the weights are automatic.... They mess up the model!

I found a good tutorial about rigging and animating in Blender and at the 11 minute he starts to show how to weight paint correctly.

I hope that helps!
