Short description of error
The new blender release (as of hash: 936014ea8c74), seems to have disabled constraints from animations.
If you set a Minimum Z for a rigid body object, it will ignore that minimum.

Exact steps for others to reproduce the error

  • Open the default room.
  • Place the cube at (0, 0, 5)
  • Add “Active” rigid body to the cube
  • Add “Limit Location” object constraint and check minimum Z = 0
  • Press play

In previous versions, the cube would drop and stop at z = 0, but now it falls to -infinity.

Can confirm.

In 2.79, the constraint was taken into account when using rigid body physics, but in the latest beta it is not.
