Applying cloth data resize my physic assets

Hi everyone,

I have imported my FBX in UE4 from Blender with a skeletal mesh. Everything is fine but at the moment i apply clothing data my physic assets move up and the mesh approx size change a lot.

I tryed it with a simple plane and the problem is the same !

I failed somewhere in Blender ?

Creating clothing data :

Everything is ok

Applying clothing data :

Mex get resized

Opening physic assets (the asset move up only if i close the asset and reopen it. If i just swap the window and go on it after applying clothing asset it stay on the floor)

I think this is my problem for my clothing collisions…

thx a lot.
