MultiBodyJointFeedback returns two times the applied one

Fixit-Davide opened this issue · comments

While applying a Force/Torque over a joint and reading the feedback value (joint reaction forces) from the btMultiBodyJointFeedback the vector m_reactionForces returns exactly double the correct value. (i.e Torque of magnitude 1.0 over the Z-axis returns a feedback of 2.0).

I found this old discussion that might be related to the problem: #3713
