@Get_Gooder I had to lurk around Megascans plugins as well.
The whole thing have been fixed, target version is 3.3.8.
I sent update files to Epic, in a day or two they release it for Unreal 4.25 and 4.26.
I can’t detail here everything done, too many changes I had to do to the very recent TAG_ANOGUID() check added in newer versions.
