Import trees from Open World Demo Collection freezes UE

When I try to import trees into my level from Open World Demo Collection.The editor freezes for hours.
I tried cut all texture to 1/4 size,but same again.
I checked CPU usage、GPU usage、MEM usage,seems ok.
I think it should be a BUG.

There’s one particular tree in the demo collection, that will always take your system out.

Answer: Don’t use that tree :slight_smile:

Thank you for your advice. I’m using another tree,now.
I still hope the bug solved in future. Or even report import failed by some reason will be better.
