Ewww, YUCK! :) The John Carpenter effect? I haven't seen it, but I would imagine that's what it is. Try deleting the rsr files from your Runtime/Geometries folder (but FIRST, 'Find' all files in Runtime/Geometries, they should be listed according to name, so you can see which rsr files do not have an OBJ file to match them. If not, DO NOT delete that rsr file) This may or may not work, and if you're not in a hurry, wait for a more definite reply. Newc
