Make Human

Here's one for those with a little more technical experience. It is called Make Human and we use it to construct figures we want to insert into photorealistic animations that our TV Production students create. There is a bit of a learning curve but there is also plenty of online help and manuals available.

This is reasonably easy to use and it produces a professional looking figure. We have spoken to professional game developers and TV art departments that use this program to develop characters for paying consumers.

MakeHuman is an open source (so it's completely free), innovative and professional software for the modelling of 3-Dimensional humanoid characters. Features that make this software unique include a new, highly intuitive GUI and a high quality mesh, optimized to work 3D character building for animations or games. Using MakeHuman, a photorealistic character can be modeled in less than 2 minutes; MakeHuman is released under an Open Source Licence (GPL3.0) , and is available for Windows, Mac OS X and Linux.
