I just saw a recent plugin exchange on one of the forums about Python and Blender.
I request a .obj export from L3DT so that the terrain can be imported into Blender and maybe other packages as well. My reading indicates that other packages use .obj too.
Although Blender has a DirectX importer (I tried it by exporting a file from L3DT), the importer did not work correctly. Also, I hope this will make other rendering applications available as well.
What to do about textures? I have no idea since I'm not a software developer. I don't know if they can be attached to .obj files.
Respectfully,
