I’ve been having some issues with color banding in my recent Unity project. I’ve tried it on both my Mac and PC and assume it has something to do with a setting in unity and not a graphics card issue.
See attached image.
One thing I want to do for atmospheric/mood reasons that are very important to me is to put a circular dark gradient in the foreground. Whether I use it on a GUI texture or use the Vignette thing, I always have severe color banding. I have fiddled with all of the image quality settings for the gradient image, tried sizing up and down the image, and done a bunch more stuff. It seems that even when I don’t use this gradient, I still see significant banding especially in situations where it’s dark.
Is there some setting I’m missing out on that will help smooth everything a bit?
Thank you very much,
Jason
The only banding I see is the standard kind you get with 24-bit color, which isn’t going to go away until we get hardware that will do more bits (and the software to go with it), if that ever happens. It’s what I would call mild banding, where you have to look sorta close to see it; not at all “severe”. If you’re seeing banding that really is severe, then I’d guess it’s something else, probably your monitor, since the cheaper ones don’t even do 24 bits, but use dithering to simulate it.

Hello people from 2014, I’m writing to you from the future, in case someone finds this old thread, like I did.
This banding issue is a pain in the ass, but it can be solved by using a texture overlay for your vignette instead of a the vignetting screen shader that comes from Unity. A texture works better because the color gradient is generally dithered.
