Have you tried adding shape name support yourself, and provide a patch?

Otherwise, please file an issue request in the issue tracker here: http://dynamica.googlecode.com
Thanks,
Erwin

For example, maya scene contains Cube1 and Cube2. The transform node name and shape name of Cube1 are "pCube1" and "pCubeShape1"; and "pCube2" and "pCubeShape2" for Cube2.

Then the geometry cache can be written as:

Code: 

<channel> pCubeShape1 <\channel><size> 8 <\size><floatVectorArray>-6.9397 -3.4768 2.53117 // positions of vertex 6.9397 -3.4768 2.53117  -6.9397 3.4768 2.53117  6.9397 3.4768 0.621983  -6.9397 3.4768 -2.53117  6.9397 3.4768 -0.621983  -6.9397 -3.4768 -2.53117  6.9397 -3.4768 -2.53117  <\floatVectorArray><channel> pCubeShape2 <\channel><size> 8 <\size><floatVectorArray>-3.38128 -2.11329 1.29456  3.38128 -2.11329 1.29456  -3.38128 2.11329 1.29456  3.38128 -0.142298 1.29456  -3.38128 2.11329 -1.29456  3.38128 -0.142298 -1.29456  -3.38128 -2.11329 -1.29456  3.38128 -2.11329 -1.29456  <\floatVectorArray>
Maya uses the shape name to map the positions to mesh, that's why I need the name of the shape node. And I thinke the name of transform would be used in the future.

So, I hope .bullet could contain The transform node name and shape name of object.

P.S. I debug into the btCollisionShapeData, but I find the btCollisionShapeData::m_name is NULL.

Any suggestions?
Thank you.
