3ds MAX: Physx Cloth Mesh Scaling/Moving

Hey all

Anyone know why my mesh keep moving and scaling out of the character when i hit Start Simulation?

I followed this tutorial Unreal Engine 4 Tutorial: APEX Cloth (english) - YouTube

Select skinned mesh, Create Clothing, paint Max Distance, Start Simulation, mesh cloth move and scale, Reset Simulation mesh move back to original position.

Also sometimes i noticed the Skin modifier is disabled with Start Simulation

Any ideas?

ok, the problem is:

this is absolute values of root bone, now i need to set these values to 100 without break the rig
