In your DAZ Studio Render settings under Advanced, you will find the area that shows your CPU and graphics cards.
Below the "Photoreal" but above the "Interactive" areas, you will find a box labeled "OptiX Render Acceleration."
In my testing, checking the box to turn this on speeds up my renders, sometimes knocking off a third the render time, sometimes even half!
Others in the benchmark thread on the forum have gotten different results, some saying this even slowed things down. I'm interested in people's results.
Here is the tutorial on YouTube.
Here is a .pdf version.
This is for those of you who are looking at the interface going, "Now what?" This covers how to convert existing shaders and how to set up lighting for your render.
This is a text version that, while different from what I'm saying in the video word by word, contains the same information.
To use this you need DAZ Studio 4.8 Pro or later.
Part 1: The Environment and Camera Settings
Before we get started, we need to check the environment, camera and render settings.
The Render Settings tab has an Editor and an Advanced section. Advanced is where you check or unc

I learned this method from jag11 on the DAZ3D forums, who is thanked for permission to use it in this tutorial!

DAZ Studio 4.8 Beta's new Iray engine also lacks a native mechanism for creating atmospheric volumes - but it can be easily convinced to produce them! They will come from your lights an
