Well, I'm certainly not the person to ask when it comes to Imagine bugs because I have yet to see any flagrant ones in 1.1. However, what you describe may have to do with your object sizes vs your world size. Try changing the SIZE parameter in the SCENE's ACTION editor under the GLOBAL actor. Actually, that is the size "channel". Change it to something like 4kx4kx4k and re-render. Anybody else have some suggestions? -- Bob The Graphics BBS 908/469-0049 "It's better than a sharp stick in the eye!" ============================================================================ InterNet: bobl@graphics.rent.com | Raven Enterprises UUCP: ...rutgers!bobsbox!graphics!bobl | 25 Raven Avenue BitNet: bobl%graphics.rent.com@pucc | Piscataway, NJ 08854 Home #: 908/560-7353 | 908/271-8878
