Hi. I've been working with forest and a surface mesh for quite a while & everything has been pretty much perfect. However, today, after installing the 3ds Max 11 64 bit service pack, all of my billboards now affix themselves to the bottom side of the terrain mesh.
I've tried collapsing all the modifiers on the mesh, removing and then re-assigning the surface within Forest, but still no luck.
Any clues or hints as to how to flip these wayward instances back up above ground will be most appreciated.
