wow, I can't believe I missed this thread. It's maybe a bit late to add my opinion, but I'm gonna do it anyway. Who are you? I'm a professional 3D and Technical Artist, in the industry for over 5 years. What kind of game are you trying to build or would like to build? We're working on cycling simulation software which features large outdoor-scenery. How does terrain fit into that? Our scenes are vast in size and almost always outdoors with lots of nature. A proper terrain-system is vital for this. What use-cases, features, workflows do you have or would like to see? I'm mostly interest in a good vegetation&trees system. I don't really care much about waving in the wind and stuff like that though. There are a lot of things I would like changed/added, but the following are most important to me: - I would like to see this bug fixed: http://fogbugz.unity3d.com/default.asp?602612_12fehc9640vmud5n As it is a huge problem. - Trees need to be able to receive and cast shadows. (without this, trees that lie in the shadow of a mountain look like they give light) - I've tried the tree creator tons of time, but I can't get a decent tree out of it, because of this I always model them by hand. So either this thing needs to be vastly improved, or all the features that are currently exclusive to treecreator-trees need to also be available for custom-mesh-trees.
