Young girl in black and white by wuruhi
Young girl in black and white
Just a simple classic portrait – still learning how to light an iray render. The conversion to black and white was done in Photoshop.

My first acceptable Iray render (I still need to learn how to properly light a scene for Iray).

Iray versus Reality by wuruhi
Iray versus Reality
I haven’t posted much this year (I have a few new images that I will eventually upload to DA) but lately I have been working on an old project and testing DazStudio’s Iray. Here is a test I did to compare IRay (on the left) with Reality (on the right). For the test I used Cassie for Teen Josie 6 and Kita Hair and, for light, DTHDR-MauiA from Daz Studio Iray HDR Outdoor Environments. The Reality/Luxrender render used Cassie’s Reality’s preset shader, the Iray render used the default SSS shader for the character.
I tried to use the same settings for the tone mapping (shutter: 1/128; F-Stop: 8; ISO: 100) but in Reality/Luxrender the image was too dark so, after a few trials, I found I had to change them to 1/60, 4 and 100 respectively and rotate the Reality IBL Sphere by 150º. In Reality I also had to change the hair from glossy to matte to get it close to the Iray render. After a few trials I set the film response in Reality/Luxrender to Kodak Portra 800. Since this was a test I rendered the Iray image with 5000 max samples and stopped the Reality/Luxrender render when it reached 1.13 kS/p (I usually let it go up to 3 or 4 kS/p). The Iray render took one hour (CPU + GPU), the Reality/Luxrender about six hours (just CPU) on an 8 core MacPro @ 2.8 GHz running MacOS 10.10.3 with an NVIDIA GeForce GT 120 (512 MB) with the latest CUDA driver (6.5.51) and the GPU Driver Version 10.0.31 310.90.10.05b12.
I like the Iray render but I’m not going to ditch Reality any time soon.
