Just created a comp that includes red solids that are spot lit, effectively creating gradients. The banding is pretty bad. Is there something I need to do to lessen or eliminate it?

change your project to 16bit and/or add a slight amount of grain to the solids.
Cheers!

16 or 32 bit actually looked like it created more banding. I'll give the grain a try.

Thanks again.

Sounds a bit as if you're overexposing the layers. try lowering the lights intensity.
And regular AE noise will do. I didn't mean to recommend the AE grain plugin which will do the job but is painfully slow..
Cheers!

[Rick Diamond] "16 or 32 bit actually looked like it created more banding"

Your display is not able to display 16 or 32 bits per channel of color information. For that reason these bit depths may appear banded on your display. If you render to an 8bpc file format from a 16bpc or 32bpc project AE will automatically introduce dithering to reduce banding in the resulting render.

All of that said I almost always add a little bit of grain even in my 32bpc projects because I like the control... and I like to look at pretty gradients :)
