Something broken in 2.82 ?

Post by addmx » Tue Jan 07, 2014 10:33 am

Hi

I'v used bullet 2.81 in my car simulation game (car suspension is bassed on btRaycastVehicle), now i'v updated to 2.82 (svn revision 2719 fron trunk)
and my car is broken (it get's crazy on all polygonal collision meshes).
The fix is to add:
rayCallback.m_flags |= btTriangleRaycastCallback::kF_UseSubSimplexConvexCastRaytest;
in
btDefaultVehicleRaycaster::castRay method
to revert to old Convex vs. Ray test.

Is this is know issue or is the new method (btGjkConvexCast) broken somehow in terms of raycast vehicle ?
