This doesn’t work for me. Seems to be an issue for megaplants in general, and needs a fix!
Confirming the issue on UE5.8.
Clean packaged build with any megaplants crashes on launch.
Re-exporting skeletal meshes from the PVE asset does not resolve the issue.
Project packages successfully; crash only occurs when the packaged executable starts.
I can reproduce this consistently.
