Hello,
I had a reference file, an fbx file attached from Revit. I've exploded the reference file and converted it to an editable poly. We made some changes in the scene so I had to expand the area. So I created another polygon surface and attached it to the first surface. However when I apply forestpack it only appears in the first polygonal surface not the second, and if I apply normal modifier and flip and unify normal than this time only the second attached surface becomes active. I've attached the file. I try to apply one forestpack to this surface but it fails. Any suggestions?
Best
