Great for matte painting I've heard.
Theres a plugin for Maya that helps out a lot, in the long run theres a lot of math involved and a lot of tinkering in the software. I've mostly brought in terrain data and use that as a base. Also be prepared for extremely long render times.
Also Vue is like a pyramid scheme, you get a few base meshes to play around with(low poly, tree leaves are just planes) and they force you to buy more meshes.
Look at geekatplay since they are the ONLY website that gives a decent rundown on the software.
