Vue trees and plants are really unlimited you just got to figure out how to use them. Vue 4.1 is the way to go. Now for the grainyness of the images well it depends on who is doing the render. Some people like that part of the program and do it purposly. If you got the time you can render perfect images. I only render in extreme quality. You got to have a fast computer or lotsa time but it can be done. Thing is it will still be faster than Bryce. There's things to grouping, last render pass optimization. There is 10,000 settings on quality really, it depends on how you set it up and what you are looking for. I'm still learning this program. It's huge. I've been at it for years. Thing is everything is sorta easy to learn just takes lots of time.
