hey joojaa,
thanx for your response, but i'm afraid that's not it...
the test sphere and the eye sphere are almost identical in their scale.
whats more, i imported the test sphere into the scene and it came with its own texture and 3d placement, but still looked different then it did before!!!
so now i went the other way: imported the "main scene" into the "test scene" and applied the material, and voila, it works!!!! so i guess that's my new-main-scene!
very weird....
