Flood light working through rainbow of colors

[RobJ]

I'm certain this is easily achievable, but can't find the right effect or setting.

I have a very typical butterfly on my megatree.  I want to have my single channel RGB flood light slowly cycle through a rainbow of color to wash the wall behind it.  What should I use?  Tried butterfly, colorwash, on, but can't get the cycling palette.

Thanks.

Use the Bars effect.

Thanks Gil.    According to the manual, bars with the gradient check-box should do what I want, but I still get hard and distinct color changes with the bar and gradient.   If I put the bar effect on the whole house model (not just a flood), and just use a pallet of Red, Green, Blue, I still get distinct bars on the model with no discernible difference when I use gradient or not.  I've used the render button just to be sure I do not have artifacts.  Am I misunderstanding the gradient check-box, or is it misbehaving?

I don't know what you're doing wrong.  This is what Bars looks like with a Red, Green, and Blue gradient.

Got it to work (of course).  Layer was set to Effect 1.  Once I changed to normal, Gradient started working.  Thanks again for your help.
