I need some trees and vegetation for my project, made with Blender (I will take care of exporting to Ogre) and the textures made with Gimp. why Blender and Gimp? Because the project goal is to make an RPG with free software only. Im using some trees I found in the Blender reposityr, but they require some weird alpha blending for the leaves that doesnt works under Ogre (if you have a mesh with scene_blend in the material, it is not visible).

Check out Glest and the various mods. They have tons of vegetation. The forums might be the best place to find it.

is this of any use? http://ngplant.sourceforge.net/ I know it fails due to not being blender.

For your existing assets are you sure you're setting your material script up correctly?

If you want alpha blending in ogre you need to set it.
