OK, thank you very much Eric. Sorry about the dupe on #1 and #2; I’m new enough to UE use I’m not on top of what’s already known, or even where to go about looking.
Whatever is up with the the crashes I see, they are not specific to mesh import in particular. I see them just importing bitmaps, for instance. I’ll attempt to collect a stack frame, if nothing else just for my own curiosity.
Glad to hear #1 and #2 are on the radar!
