[X3D-Ecosystem] Soft body physics baking in Blender X3D export

[John Carlson]

Note, humanoids with 20 joints bake quickly, 120+ joints, tens of minutes.

What I am attempting to do is get 20 joints for prototyping and then bump
up to 146-148 for final.

I’m doing a variety of Python files, and not using the standard Blender
exporter.
