I'm using a pack that I bought frm the Content Store  that was originally released for IC 5.x. It has a single diffuse map for the mesh and everything still seems to work great in IC 8.x. However, if I export the prop as a FBX file to Blender, and then import it into Blender 3.3 using either the default FBX import tool or Soupday's great CC/IC Pipeline plugin for Blender, the UV map for the prop's mesh is WAY off.
   Does anyone have any experience with this? I'm hoping that there is a reasonably simple way to fix this. I have tried the brite force approach of UV unwrapping the mesh in Blender and then trying to fit the pieces to the Diffuse map like a giant jigsaw puzzle, but to no avail.

Is there more than one UV map in the mesh? It might be defaulting to wrong one.

Dude, you are seriously brilliant! I didn't fully understand what you were saying at first. I had no idea there could be multiple UV maps!

I started by examing the model in iClone and could see there was just a single texture.

So I re-exported it to FBX then used your Blender addon to import it.

I then selected the mesh, went to the Object Data Properties, opened the UV Maps section and noticed the 3 different channels. All I had to do was to activate Channel 1 and presto! The correct  texture map was used.

So you simultaneously solved my problem AND taught me something important about Blender! I can't thank you enough!
