John, Thanks.

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.

Also, I don't know if there are such things as copy protected textures, and if there are, this script doesn't yet check for them.

In order for it to check everything, it's imperative one ungroups every object in a scene. This script doesn't 'walk' the groups yet.

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

The script can be found at:

Just put it where you want and run it.
