Attached Link: Tree thingy

Not that much experience. I actually think most of you have more idea of how things work in bryce than I do. The background forest in that pic (link above - its a pretty old pic from when I was learning to play with trees) is one huge multireplicate job and a random resize applied later. I didn't see any of the render glitches in that. Eelie - your second question - you could try copying the tree and pasting into your scene, rather than duplicating - not sure if it'll work, but worth a quick try.
