Best file format for models, maps, skeletal animation, etc.

What do you advise?
We want to use X3D.

Thanks.

There is the most support in CS for Blender (blender3d.org), and CS has its on map format.  Skeletal animation is best done with Cal3D.  Look that up in the documentation.  I also seriously doubt that there is any direct converter from x3d to any formats that CS can read.
