Aye, good solutions, JOhnny and Ek-art... I'll give them a whirl when I get home, see what happens. Methinks that if I export both main terrains (the crag and the immediate "floor" terrains) to Rhino, perhaps I can accurately model a better path. Of course, in Bryce it's nearly impossible to interact properly with the terrains, as there is no collision detection, merely a modified bounding-box technique. SO if I do a drop-down of the existing steps, nothing really happens that's worth happening... Buildings should be an easy fix. They are all separate models, created by slicing apart boxes and octas in Rhino with heightmaps (terrains). If I simply duplicate and shrink the duplicates down a bit, and apply a different mat to the duplicates, it should help add to their solidity. And some chunks of concrete wall and whatnot would also help...! (thanks, Ek!) The trees? Well there's not much I can do about them other than rotating them around randomly. Again, Bryce has no physics to handle such things... I COULD export the terrains to Maya, and then make POV-Tree trees, cut down their polys in Maya, and use Maya's physics to actually collide and slide the trees into place. But that would involve me setting up dynamic weights for the branches, and a whole lot of other things... And if I had wanted to use Maya at all for this scene, I would have just done the whole thing in Maya! So I don't think I'll change the trees, but I might move them around a bit, or get rid of the distant ones...? Thanks for the input, everyone!
