I did a Make Human export to an mhx file with the "Rotation limits" and "Export for Rigify" boxes checked. When imported into blender I found I was able to make the knees and elbows bend the wrong way. By this I mean in such a way that would break the joint on a real person. Given that "Rotation limits" were in effect when I exported, should I be able to do that?
In Blender I did not see any bone constraints in Properties.
