LS, Please check my gallery for a (I consider) nice chopper rendering with nice chrome effects. I know scratch about motors, so don't blame me on techically incorrect stuff. If you want to, you can even download the file that I used as environment for this rendering. Please let me know what you think of it. Please also check my macros in the software/macros section. Some are very handy. Soon I will upload some other macros. Kind regards, JJ [URL="http://www.studiozwaard.nl"]www.studiozwaard.nl[/URL]
