Hey gang,
Thank you so much for this thread, it helped me sort out how to pull this off. I’ve also got framecounts other than 2x2 working. Below are images showing a 4x4 atlas randomizing.
Here’s one detail that tripped me up… might be worth explaining. After the particle random value node there’s a mulx4. I originally plugged that directly into the append, but you only got the numbers 1, 6, 11, 16 out of that. To fix that I had to come up with two independant numbers. So for the V channel, a mulx4 and a round gave between 1-4. that worked. Then, for the U channel… I multiplied again by 4x before the round, giving a 1-16 rounded. I’m a little fuzzy why this works, but it seems to disassociate the u and v random results. It’s all divided by four at the end of the chain.
