It's not that Peyote (and other things) per se float with viewports. It's that when you SWITCH the viewport such that the terrain at viewport coordinates X,Y (which has the Peyote or whatever) is a different height to the terrain that previously appeared at that (X,Y) coordinate with the previous viewport, then the game engine seems to retain some memory of the height it thinks that X,Y has even though its been given a totally new terrain and marked as dirty (same as if you'd changed the terrain in Worldbuilder in essence so far as the game engine is concerned)
Ah... right. Ok, so it's like it might think that peyote on the plains there should be on a mountain. I understand. I remember reading the threads that got that project started and I do know its a lot about trying to trick the map mechanism into thinking its delivering something its not in a lot of cases. Makes sense.
