I hear you, but unfortunately I don’t have the time. Thing is, Character Customizer is a project that involves many different areas of content creation/scripting. People have asked me for tutorials on 3D modeling, animation, rigging, texturing, UI design, even general game scripting. I can’t keep up with the demand.
The time I do put into this project I prefer to spend on working on updates, making it more accessible by design. If you have a question I will try to answer it, preferably by email, and the more concrete your question is the higher chance I can give you a good answer.
