From customer:
"In the StaticMesh Export option, when bExportSourceMesh is set to True, exporting StaticMesh Assets and importing them into DDC tools such as 3dsMax or Maya results in the UVs being imported in a fragmented state."
| Original with UV borders | After being exported from UE |

Repro steps:
1. Create a Teapot mesh in 3dsMax.
2. Import the Teapot mesh into Unreal Engine.
3. Export the asset with bExportSourceMesh enabled.
4. When import the Mesh into 3dsMax or Maya, can see that the UVs are all split. If do not enable this option, will see the same UVs generated by the DDC tool.
