Excuse me if I'm being dumb here. My understanding is that if I place a tree in a scene, and edit the parameters in the tree lab, and set a high randomness factor, then if I now copy or duplicate the tree I should get a different tree with the same properties. But I seem to get exactly the same tree. What am I doing wrong?

Copy/duplicate tre THEN go to tree lab and change randomness :)

Also, when a tree is saved as a .bto, each time you create a new tree from it through the Create menu, the tree will be a bit random from the original.

This is not my "second childhood". I'm not finished with the first one yet.

If I remember this correctly, when ever you create a whole new tree by clicking on the Tree Icon, Bryce creates a new random "seed" number and the randomize TL button always uses this seed. So when you copy a tree it still uses the same seed which limits the amount of overall randomness. If you manually copy the TL parameters over to new trees, you get a much more random tree. Image above first shows 3 copied trees with Randomize set to 0, 70, 100 - not a whole lot of change. The bottom shows 3 new trees with the parameters hand copied from the middle tree.Bit of a pain but it's more in line with what I would consider random. HTH; Dan
