As of CVS version 1.36 MOSAIC is now compatible with Blender 2.46. In particular it can now export the new particle systems with support for multiple materials for points, hair, billboards and objects. MOSAIC also supports the new soft shadowed raytraced light controls through the built-in shaders and tokens.
PLEASE BE ADVISED AS OF MOSAIC 1.36 SUPPORT IS BROKEN FOR BLENDER 2.45 AND BELOW!!!! This is an unavoidable result of using the new particles system. Hope everybody enjoys ;)
