Shadows preview Offset

Hello, 

Within substance painter if i re-import a mesh with a different size the shadow preview get a offset and will be fully black at the base of the model. I made test and it will only do this if stroke preservation is turned on with the new import. 

Step to reproduce:

First i export FBX (meter unit, 2 materials) 

Then i re-import mesh with extra parts moved, changing the bounding box of the whole object.

the same import without stroke preserv

The reason i often do this (re-import) is because despite the bake by name option, there is often mesh you want to duplicate move arround afterward. 

I hope they could be an easy fix for this ; )
