After a long break I’ve prepared a new small tutorial.

In episode 12 I give you some tips how to use Blenders baking system. Especially you‘ll see a solution for baking the alpha channel to get transparent objects. This is not done automatically in Blender currently, but there’s a smart trick how to do it anyway.
