Hi,

is setLocalScaling() supposed to work when btBoxShape()::initializePolyhedralFeatures() has been called ?

The debug drawer doesn't seem to scale the box shape being rendered; it seems to be a debug drawer bug (going to investigate right now), however, the makes me feel that nobody has used this feature before, hence I am not sure whether this combination is valid or not ?

Thanks.

setLocalScaling is not supported after calling initializePolyhedralFeatures. The polyhedral mesh generated by 'initializePolyhedralFeatures' is not updates anymore afterwards, so changing the collision shape afterwards is not a good idea.

(you should be able to check this in the source code)
Thanks,

ok, understood, thanks for the answer !

BTW, what's the advantage of generating such polyhedral meshes, does it only speed up broadphase (and/or any other part of the detection), or does it helps with any other aspect ?
