ID Color Map Baking Artifact Issue

[Ira22187698juiq]

I created a high LOD and Low LOD version of a set of meshes using Blender.  All of the meshes share the same material.  When I bring into Painter and bake the ID map, I get a strange artifact when using the higher LOD file in the baking process.  If I eliminate the high LOD file, the artifact goes away.  If I isolate the one mesh out of the set and bake using the high LOD mesh, the artifact also goes away.  I made a video of the process here: https://youtu.be/JPoBf42IyzQ.  

I've also attached the files.  Any help would be great!

By the way, I'm using version 7.4.0 of Painter and 2.93.4 of Blender.

In case anyone cares about this one, I found a solution although I'm not certain as to why it occurs.  I think because I have so many meshes spread out in this fbx, I had to clear "Relative to Bounding Box"in the High poly settings under baking.  I probably should try using a cage file, but instead I clear this and increases the distance front and back to 1.  that has fixed the problem.
