Looks like the issue is relegated to the
Dichondra argentea_groundcover family of plants. All of the others appear to be working fine. There are some general issues like normal maps being assigned as bump maps. But this is a great addition to our library overall. If some of these minor mapping issues could get ironed out by Globe Plants the colleciton would be even better.
FYI- i purchased another sketchup bundle (high-res) that was noted as being for Enscape, but it does not include asset packages and requires a bit of work. I reached out to them to see if they would swap for the Blender version as that is a better workflow for getting the content to Sketchup/Enscape.
