Can somebody please tell me how I can animate a rainbow starting off from a corner of the scence and completing at the end of the screen. Thanks

You'd want to have a 2D pic of the rainbow on a 2D face in Bryce and make it Positive in the Attributes box. Bury it in a negative Cube and group the two. To animate, slide the box (within the group) in the direction you want the rainbow to move until it's fully visible. You may also want to make the cube huge and angle it as it moves so that it 'appears' in it's own shape instead of being swipe-shown. I hope you understand what I'm trying to say and good luck with it!

I was curious so i fiddled in the sky lab - you can move the rainbow with the sun control and change the colors that way also. and you can make the rainbow bigger or smaller with the skylab rainbow control and just animate in the skylab direct adding a keyfranme for the sun motion, halo and sun colors. (or just choose all in the sun keyframe option)Let me know if you need setting as reference

this animation is very cheesy but it was just to show movement

Or I think you could fade it out in the skylab too.
