Help, Not quite getting workflow Blender->Substance Painter->UE5

Hello!
I've been spinning my wheels and wasting a lot of time, so I think I should reach for help!

I've modelled a character in Blender, UV'd it and rigged it. Brought it into Substance Painter to create textures. Then applied those maps to the Blender model in Unreal Engine 5.

Result: Texture lines look distorted.

 

After a search, I see that the solution is to use the mesh exported from my Substance project. When I bring that into UE5, the textures look fine but the rig has been lost.

 

Next, I try importing the FBX from Substance back into Blender and re-rigging. But when I take that to Unreal, the textures are distorted again (not sure why, it seems to be the same triangualtion.)


I'd be grateful for some tips on a workflow that will (a) produce clean textures in UE5 while keeping my rigging and (b) keep thing as flexible as possible ie. being able to make updates to model/paint/rig without having to redo a lot the other aspects from scratch.

 

Thanks!

Btw, all this is happening on a Windows 10 machine, fwiw.

Correct answer manraytrace

Well, to answer my own question, in case anyone else has the same problem:
I managed to get undistorted textures by following this procedure for importing the asset to Unreal:
1) In the Import dialog, make sure "import Mesh LODs" is unchecked.
2) Open the asset in the Mesh Editor.

3) Check "Use Full Precision UVs".

4) Check "Import Mesh LODs".

Result: The mesh will be reloaded with clean, undistorted UVs.

Seems a bit complicated, but...
