To be honest, I've tried physX only when the first beta version of A8 came out. Didn't try it with new version yet)) Is there any other way than locking models X?
Yes, like I said in my previous post:
Anyway, if you are resetting a physics object every frame using my.x = 0, make sure to disable and enable the physics object as well every frame using phent_enable.
obviously, instead of my.x, you can also do my.y here...
