Importing Animation Names Issue in UE 5.5.3

Nah just make a backup and use version control as normal, then do a test run.

Your current solution of disabling interchange might not be futureproof. For me, UE 5.5.4 and Blender 4.3.2, I found that BOTH were adding to the ridiculous prefix. Blender altered the prefix when exporting to FBX, then UE altered it again on importing. To fix that, Interchange was the only option. I screenshotted that Interchange setup that I used to fix it, and at the end of those nodes you can see I still had to remove the “Armature_” prefix from the name, which is what Blender added.
