Hi
thanks for looking into this.
I have reverted back to the default and now it takes 10-15 mins to do one pass, If i could improve that it would be great. As I will probably send this to a farm to render.
With a standard material its much faster but it does take a while to clear the noise, and I noticed this even when I have a simple geo around it like a cylinder. Is there an issue being in a small enclosed space.
I will try a translucent material as well.
