Rays/ Lines when exporting image views


I’m getting lines/ rays across my drawings - mainly the floor, when I export from layout:

They don’t appear this way when I view the image in the layout viewport.

I’ve tried exporting as a PDF and Jpeg. I’m using Rhino for Mac.

Any help would be greatly appreciated!


I believe we need more information to understand what we’re dealing with here. It could be your graphic settings, or some bug in Rhino itself. But, if we are not able to replicate it in our computers, We might not be able to help you out.

What file format are you exporting?

It looks just like regular banding you get when trying to display a smooth gradient with a limited number of colours.

Two solutions are:

  1. Pick a file format which supports more colours,
  2. Add slight noise to mask the banding.
