An old oak tree map model originally created for a Quake3 map modeling contest in 2001 (won a editors choice extra price).
Includes the original pk3, obj meshes (one with leaves, one without), three different types of leaf-skins and to bark variations.

thank you, the variations are especially useful.
The material files referenced by models/*.obj files are missing.
For my own purpose, I made them myself by hand :), here they are so others can use:

Given Ns, Ka, Kd, Ks colors are pretty dumb default material. Given map_Kd use appropriate textures on appropriate parts.
For my own purposes, I needed the tree model to be in Blender (and exportable easily to VRML 97). So I made it, and here it is:
Blender version: https://vrmlengine.svn.sourceforge.net/svnroot/vrmlengine/trunk/demo_mod...
VRML 97 version: https://vrmlengine.svn.sourceforge.net/svnroot/vrmlengine/trunk/demo_mod...
I preserved the geometry and texture mapping (actually, Blender Wavefront OBJ importer did :) ). It's split into two Blender objects (main part and leaves), so you can simply hide/remove leaves object if you want a leafless version.
Note: if you want to render from Blender, you'll probably want to set Alpha=0 on leaves material to make them honor texture transparent regions for leaves. Currently it is set to =1, to make VRML exporter behave Ok.
oaktree.wrl is the above Blender model exported to VRML 97 by my script (very slightly modified version of Blender's "VRML 97 Export" script) from http://vrmlengine.sourceforge.net/blender_stuff.php
