I’m looking for a 3d model (or event a ground texture or something) of one of the London airports. Do you know of any blender compatible downloads that would help me?
Try downloading Collada versions of models. Many times they fail to import, but it might be your best bet.
Extend or refine your search as needed.
If your looking for a texture how about
I did a google image search of “arial photo of gatwick airport”
is there a wiki page doc for uploading sketchup files into blender
with minimum of mess up ?
