Don't apologize, Duane, the forum is here for asking questions :) Anything Glows that is used for Environment Lightning does not exist for RDS, only Carrara (and version 2.5 is part of Carrara Studio) . There are soft shadows in RDS, so you can definitely use them with a row of bulb lights to simulate a neon . Plus, in RDS the soft shadows can go through transparency :) litst
