Although I found plenty of information and really awesome tutorials about rigging, skinning and animation, I ran into some problems on the way to my first animation. So in this posting I list all my problems and the solutions / workarounds I found for them.

Using Unity's ragdoll wizard leads to the problem that the prefab connection to the character model is broken. That means after a change of the model in your 3D software yo have to perform the whole procedure again. To avoid this I wrote an open source code generator that saves all ragdoll components in a C# factory class which you can invoke at runtime.

OK you have got a high polygon Blender model with let's say 10-20k vertices, maybe bought from one of the 3D model shops out there, and now this needs to be decimated because processing of animations takes ages in our game. How can we do this in Blender 2.5x/2.6x?

I am no Blender expert (not yet) and I started working with Unity3D just a few months ago. Setting up the work flow of importing 3D models created with Blender was a bit painful. So if you are about to start with Blender and Unity3D, this little checklist might be useful for you.
