PxContactModifyCallback for CCT ?

[rouxfrancis]

I would like to be able to modify the contact points that apply to a character controller. For that I modified its shape's simulationFilterData as I would have done on a classic rigid actor, but it seems that the filter shader is not called in the case of a collision between a CCT and a rigid actor. Am I right and that it is impossible to modify the contact points that apply to a CCT? Or maybe I made a mistake somewhere.
Thanks,
