Iray SDK is super easy to use with well-written documentation and the photometric lights, shadows, and material texturing is top notch. The rendering and performance it adds are just out of the world. You should definitely try it out. Review collected by and hosted on G2.com.

There aren't any downsides if you ask me, I was trying it and it was what I thought I should have gotten way back to help me complete my tasks way easily and comfortably. Review collected by and hosted on G2.com.
