I am starting with a grid, appending a point SOP. I am then attempting to randomize the color of each point on the grid, in order to copy a geometry to the points and have them inherit the random color.

any suggestions?

thanks in advance.

nevermind - I found my answer.

Would it be possible for you to do something like rand($PT) in your color channel?

Other things you can look at are noise(), snoise(), turb(), sturb() function.

Hope that helped.

I would use rand() together with the point position so rand($TX)*256 for the red channel rand($TY)*256 for the green channel ...
Also i would use a multiplier ( * 256 ) because rand() gives back a float value between 0 and 1 .

Hope it helps
