Material ID percentage by height (like Beiging watercube auditorium)
I need to generate randomly and continuosly changing seats pattern in the auditorium, based on two colors of the seat. Let's say from solid blue at the bottom, through mixed, to solid white at the top. Just like this watercube auditorium in Beiging. http://farm4.static.flickr.com/3079/2545312854_0150dde999_o.jpg
We have as a starting point a the auditorium made up of simple seats (each with pivot point at its centre) which should be replaced by the blue and white vrproxies in the fashion as per the image.
Up till now we've been doing a random coloured auditoriums by usin a little script without a problem. What I don't know how to do is to have the randomness (or ratio of the randomness) change with height.
Thank you for any help.
