Export light rings instead of shade of light

Hi everyone, I'm new here so first of all thank you all for accepting me anongst you.
My problem is the following: I have a scene (LOGO intro animation) that plays fine in Motion 5 but when I export it, the lights doesn't look like a normal light shading gradualy. It looks more like rings of diffrent colors with abrupt transitions. Does anyone knows what's going on there?
Thank you in advance.

Yes, the "banding" problem with Motion. Export as ProRes 4444 and see what happens. Make sure you're exporting at Best quality. Has to do with the bit-depth of the image.
