How can I save UV coordinates into .obj when using curves I have used the sapling tool to build a tree for myself. I would prefer not to convert the curve to a mesh to make life simpler if I want to modify it later.

I added a texture and adjusted the scaling so it looks correct with the 'Mapping' section of the 'Texture' tab. When I export the model as a .obj and load it in to opengl, the texture coordinates are all wrong, they are so distorted! I assume the scale factors I have set in the mapping section are not being accounted for in the exported file? What should I do?

Is there any way to see how blender has UV unwrapped this mesh (without converting the curve to a mesh?). The texture mapping is not perfect and it would be nice to edit it a little!
Turn on "Use UV for mapping" in the texture space options in the Object Data tab of the properties window:



Turning on this option will generate UV maps for when you convert the curve to a mesh, or export the curve to .obj, since .obj doesn't support bezier curves and converts the curve to mesh as part of the export process.
