Since the Tree Creator was designed to only create trees over a certain size we need a way to be able to scale the trees after creation. Simply scaling the trees does not work when added to the Terrain Engine as the trees are rescaled to 1,1,1. Ideally this scale factor would be at the root node of the Tree Creator, but it could also be a setting in the "Add Tree" dialog for the Terrain Engine. I'm attaching a cactus that demonstrates the problem. I had to create it at an oversized scale in order for the branches to work. However it's way too big for a cactus. If it could just be scaled after creation (and work on the terrain) that would solve the problem.
