hi Everyone:
For a job that film 2k render setting was requested with Maya 4.0.
I have set a spot light focus to one model in the maya scene,then have a banding problem in the gradients.it gave me big trouble,how to reduce it!
Any suggestions?
Thank you for your help.

which gradients are you talking about?

Are you getting banding on the large / single-coloured surfaces on your scene? You might need to add a fine noise texture to "break up" those smooth transitions.

Please give out more information about your scene, and if you can, post an image of your problem scene, that way it will be easier to recommend a solution.

Use 16 bit render.

use logarithmic colorspace.

Should solve the problems.

Also if your scene is rather large try turning off 'USE MIDIST DMAP' and also adjust your DMAP bias. Hope it helps.

And in Maya how do you change color spaces??
