The Claymod public beta is now available. You can pick it up at:

As you may know, Claymod is intented for creating high detail models and normal mapped low detail models (using a high detail model as a reference). It was written using the Irrlicht 3d engine. A typical workflow might consist of making a basic model in another modelling package, exporting it in a format claymod can read (OBJ is a good bet), doing your detail work and generating your final model with normal map and texture from claymod, then bringing it into another program for animation. Alternately you can do all your modelling in Claymod but your current options are a bit limited.
Please post any issues or comments here. I probably won't have much time to offer support this weekend, but I will be around..
