Quote - I've written a Python script based on your hint which does correctly identify copy protected Meshes. It currently won't work on copy protected metablobs, or other primitives, though I don't even know if there is such a thing as a copy protected metablob.

Well, metablobs can only contain primitives, which are not copy protected. So the only way for one to become copy protected would be to allocate it a texture from a copy protected mesh. Fairly easily avoided I would have thought.

Quote - Also, this script DOES NOT CHECK for copy protected Solid Growth plants. If you know of another way to check, let me know.

Now that is a headache I think. An instance of an SG plant mesh is not locked for export, but the SG plant itself is. After all an SG plant is not a fixed mesh, it's fractally generated from a random number seed. Might have to spend some time thinking about that one.
