So I thought to share couple of tricks that helped me alot to achieve higher rendering speed with IRAY in DAZ
Though most of the experienced Artists must be well aware about those quickies already.
It may help newbies or artists who are having old NVIDA GPUs or not so high end PC (like me)
Here are some of those tips -
1. Iray Uber shader
