Ok - had to revert back to iC 8.5.4 for reasons already mentioned; I do not have access to UE Live Link in iC because only v1.36 is available and it forces you to upgrade to iC 8.6 (not gonna happen.)
So, I exported said character via FBX into UE and chose the HQ shader option; I then create a CC rig by right clicking the skeletal mesh → Create CC rig option; I then try to test and get a blueprint compile error in [MyCharName_Rig_BP; I’ve attached the screenshot
