Tutorials/Help in Blender

Hi FNAF community! I was wondering if anyone has any instructions/tutorials and such to help me learn how to model fnaf animatronics. I can do heads okay, but I struggle with the body. I use endo 01 prefabs as the base, but just cover it. I use blender.
whenever i render an animation blender crashes a few seconds after

If anyone has nothing else better to do, you can fix the rig and rig it. Oh and add rigs to the fingers. (moving posts to different channels is possible this was on w.i.p)

So I was trying to rig ban ban with automatic weights and, this happened, can someone explain?
Why is the sun disc unavailable on the sky texture node?

my first export from Blender to Cinema 4d(does anyone know how to fix the texture)
