I made this tutorial for a friend, and decided I would share it here as well. I am not covering the very basics of Blender, so this will help if you have some Blender understanding already. Any questions, feel free to ask in the thread and I'll try to help! Also, the adorable toddler model I use is by the wonderful Feyona and can be found here.
