I had heard of MakeHuman a couple of months ago, and late last night finally got around to trying it. I'm very impressed! This software is easy to learn, and even as a total newbie I was able to make two very nice-looking characters in about 90 minutes. That was 60 minutes to play around with the UI to see where the knobs are and what they do, and 30 minutes to actually make the two characters.
Importing into Unity is a breeze, and I really love the workflow for textures and materials. Having different body parts, clothing, and accessories separated allows me all sorts of customization options in Unity, and yet the basics are shared across multiple characters which will mean fewer draw calls. If I need texture atlases, I have an add-on within Unity to do that, so I'm glad you didn't force that issue.
I'm a programmer, and although I am moderately proficient in Blender for architecture, furniture, and so forth, I'm not a character artist. MakeHuman empowers me to fill the gap with first-rate results.
Thanks for making an excellent tool and making it available for free. I'm planning to follow your example if I create meshes for clothes and such, and release them as CC0 freeware.
