Using an Opacity / Transparency Map in DAZ Studio (Iray)

Transparency is handled differently across render engines and file formats. While a PNG, TIF or GIF file can contain transparency data, a JPG image cannot. DAZ Studio’s Iray render engine can’t handle transparency data embedded in such images and requires the use of a special Opacity or Transparency Map. This might sound a little confusing, …

DAZ Studio Render Speeds – The Results are in!

A while ago I’ve asked you all to download a test scene and see how fast it renders. Everyone’s got a different graphics card/RAM/CPU setup, and I was interested to see how DAZ Studio would perform with those varying configurations. After all, most “review” websites only put hardware under scrutiny using video games, and for many of us, that’s just not how we use our systems.

I must admit that I’ve been trying to write out a nice looking and well formatted table many a time, but it just never got done. It had always been my intention to share the results with everyone, so rather than keep you waiting and go through all the graphical pain of making a lovely looking spreadsheet, I’ll just share the raw data with you. I’ll also let you know how I interpret it in simple words, with the intention of finding the most cost effective configuration for working with DAZ Studio. Here it is – the Google Sheet we’ve all been waiting for:

This is a view-only link (I think), and additional submissions will be added from the form on my other article at the bottom.

What does this data mean?

From the looks of it, using DAZ Studio 4.11 in 2019, the fastest render results for the lowest amount of money can be achieved using any variation of the NVIDIA RTX 2080 card.

The only one faster is the RTX 2080 Ti, which aside from more RAM (11GB vs 8GB for the 2080) is also clocked slightly faster, resulting in faster render speeds. However, the price jump is remarkable for the Ti (almost double when compared to the non-Ti version), and in my opinion for DAZ Studio it’s just not worth it.

About that Denoiser in DAZ Studio 4.11

There’s an article by Phil Miller that explains NVIDIA’s philosophy about the new interactive Iray Denoiser.

Thanks to deep learning, NVIDIA’s own DGX-1 AI Super Computer and a lot of trial and error, this machine developed an algorithm that can predict how accurate the final result will look like when only a limited amount of ray bounces are available.

In a nutshell, their Artificial Neural Network went ahead and compared a partially finished render with a finished one, and each time it made a prediction that was not looking handsome, it learnt from it. Eventually they came up with what’s currently integrated in the latest release of Iray, which has made it into DAZ Studio 4.11, and that in turn is available for us to beta test right now.

I’ve run some tests with this new toy, and I’m excited to share those with you today.

How to create dramatic lights in DAZ Studio (Iray)

In this episode I’ll show you how to create a string side light in DAZ Studio 4.9. The default light looks very soft and does not create a dramatic effect, so we’ll see how to remove those first, and then apply our own parametric spotlight. In addition, we’ll add and tweak the default IBL to …
