There's the occasional render bug, but planetside does a pretty good job of getting rid of them when they are found. And these bugs rarely ever pop up until you start using things in ways they wern't designed to technically be used, or creating very odd displacements and extreme number values, etc. tg2 is still technically in beta, but the actual release is just around the corner now.
also if you are wanting vegetation, xfrog plans to release a low cost dvd at the same time tg2 officially launches, with a nice variety of plants for a good cost (so they say so far), which if you were into purchasing some nice plants, that would give you a nice quick boost to your library of possibilities. you can also scout through our image sharing and file sharing forums, to get an idea of what kind of images people are making, and what kind of things people are willing to share with this community being so nice and awesome. though, just a quick note that many plants in the file share are currently dead links, due to the whole lightning thing. but there still plenty of great things out there.
so really, while terrain is terragens very great advantage, it has been going leaps and bounds towards high quality models imported from other programs. recently most my renders have consisted of A LOT of vegetation, and they've turned out great (at least, i think so
)
if your looking for backgrounds though, tg2 wins in clouds, atmosphere, and terrain. hands down.
