Ah! Thank you! So that's where the bowls are. I had one of Thierry's basic shapes packages but I didn't realize there was another one. When I saw the bowls in the map I did suspect they were something Thierry might have made.
I suppose I might just have to search around for rock meshes unless someone pops up here with them.
And I'll have a dig through my default object folders for the den and ferns.
As for the particles, I did look through Glave's particles prior to posting this thread, but I didn't seem to find anything that resembled the ones in that map.
