Unfortunately massive usage of dirt can lead to significant speed drop up to 3 times in this picture.
It would be great if octane could bake dirt map to a bitmap texture. That way one could tweak it a bit in paint application and also slowdowns wouldn't be a problem.
Hi matej. I tried your script and it works nicely:) Excellent work. Can you please tell me if is it possible to achieve random Z rotation with you script? That would be very usefull for trees and vegetation.
