Error after changing BP parent class: “OwnerClass should not be 'REINST_'!” (UE4.27)

Development Programming & Scripting Blueprint

For a Blueprint compilation I think I found a workaround. You can enable alternative blueprint loading mechanism with BP.bEnableSkelReinstUpdate variable.

I’m adding a line to Engine\Config\ConsoleVariables.ini before running UE4Editor-Cmd.exe

BP.bEnableSkelReinstUpdate=1
