OK I can repro this. In a clean scene, create two icosohedrons, one radius 100, the other radius 2000. Put a lambert on the small one and apply a cell texture onto a bumpmap. Create a spatial projection and scale it's uv's to 200. Now this works, the inner icosohedron has the bumpmap applied ok. Now if you change the size of the outer icosohedron from radius 2000, to 3000, the bumpmap goes haywire. Any thoughts? I've tried changing the clipping planes but that didn't work. Chris
