Real-Time Physics Simulation Forum

I've written an open-source export script for Blender that extracts compound physics collision shapes authored in Blender and writes them to a YAML text file for use in a Bullet physics application.

Your C++ application will create a parent btCompoundShape and then parse the exported YAML text file to create the child shapes. The exporter supports the following shapes: Box, Sphere, Cylinder, Cone, Capsule, and ConvexHull

Here's my blog post with more information about the exporter:

The python addon script is available for download on my Google Code repository (see blog post for link).

Have fun!
