I need to make trees. Lots of them. What I'm trying to do is create a basic trunk mesh with lots of planes that have a branch/leaf texture. I don't actually want to generate all the branches in 3D, nor do I want to create billinos of leaves.

I have a few excellent tools for creating trees, even on the lowest settings they are still too high polygon for me. So before I start modeling and exturing like crazy, does anyone know where I can find resources for very low polygon trees? I'm especially looking for branch/leaf textures with alpha maps, since these are a bit tricky to create nicely.

Any resources?

I take it you don't want to go for bilboarded trees, but actual 3D ones?

You can usually get away with two billboards at a 90 degree angle with the other one forming a plus from above. You could use your low poly trees that have too high a poly count when the player is close, then in the distance use the simple sprite based trees for fillers.

Yeah, take a look at some info for imposters. Using higher poly trees at very close locations, and only updating the billboards when the angle of the distant trees changes.

Hi
yes Leiden many flight simulators are using this approach by applying to perpendicular billboards as a tree.

or as Darkshadow said imposters is a very good approach, you can learn about them from

it is the Openscenegraph approach.
