Softbody from trimesh

[falcosolitario]

Hi all

Need an answer if it is possible.
When I create a softbody from a trimesh does bullet alter the vertex number ? (i mean some sort of triangulation, splitting the face of the geometry in order to allow breaking of the object...)
This could be the case for my problem for softbody and their weird movement and errors.

Thanks
