PhysX Lab 1.1 + 1.2.1 Large mesh problem

Just started doing some destructables for an UDK tutorial and found that if the mesh size is big then the fracture doesn’t work in the F12 playground

eg i make a box 64x64x64 units this will fracture but not re-act in playground or in UDK

eg i make a box 1x1x1 units this will fracture and works in playground and in UDK

as you can imagine having meshes the size of 1 in a game doesn’t go very well as you will have to constantly scale the mesh every time you place it

btw the fracture map works fine with a large mesh !!!
