Thanks Jay BuzzinFly, I'm saying to use lights as usual and have the the light surface only serve to give the light sources a physical representation. Pretty much what it says here in the help files. As for glow in post, in my opinion its better this way because: - Baking it into the raw render locks you into a certain look unless you re-render. It's a post process effect even inside Maya(which is why you can't see it until the render finishes) - There is one shader glow in Maya so its the same behavior for all glows - There are much better looking glow effects to be had in external packages
