There are two simple ways that I know of... First You could select an object that you want to have a neon effect on, click on the "m" to go to the Materials Lab. Here make the object's Diffusion and Abience the same color, and set both to 100. Now you have a neon object. Second You could also set the object to "Additive" which would give it a neon look, but it is also a bit transparent, which didn't help me much when I made my neon clock (in the bryce free stuff section just incase you want to check it out). Good luck! Adam
