LC#44 Getty Bewnchmark Challenge

Dear All,
while waiting for a wonderful scanned human character from a well renowned website since in Italy it's quite hot and I was reading the latest paper about SIGGRAPH 2016, I've decided to create just a few small images that represent some technical challenge and can be used as a benchmark for your favorite render engine. At the end of the challenge I also ask if it is possible for you to share your final and textured model so we can create a library of the best scenes to use them for comparison purpose. Let's see more in detail the challenge

Eggs + Porcelain: Multilayered reflections. How well does your favorite rendering engine holds up to multiple bounces required to create these effects?

Gelato: Foam, reflections, thin and thick materials all behave differently when it comes to light. Reflections on the glass, the SSS materials, and caustics from other glasses. How far can you can push the limits of your favorite rendering engine?

Glass Jar & Coins: Glass reflections and metallic reflections. How does your favorite render engine handle the bounces of light between glass and metal materials.


If you intend to use references (recommended), make sure to include a copy of the reference image(s) that you use to allow others to provide critiques and comments in context to the reference image(s).

Also as always

Hello,

Good idea to share the scene for this one, let me know what you think about my first test :

Maya 2016, Mental-ray 1280*720 19min(no optimisation) on i7 950.

That's really a cool render ! The yolks look good, the table need a bit of re-texturing. Didi you had a look at the reference in Getty site ? Can you try also with a camera angle on the top ?
waiting for more.

Which index of refraction did you use for the glass ? It seems quite too transparent. The IOR of glass should be in a rage of 1.3-1.7 (heavy glass).

Hi Jojo,

Is it more like that you wanted the render to look like ?


EggYolk 4

Modified the volumes to match the reference ; used the GI next solution from Maya-MR, so it's slow and grainy.

FeD: Your renders and shading continue to impress me a lot. Very realistic. No crit's to add, just can you explain your workflows a little, as I'm sure a lot of people like me can learn a lot from how you do things.

kosingcg: Apart from what jojo said, My other concern is the shadow colour. it looks green but the glass shows no hint of green anywhere as far as I can see. Great start!

Hi again,

ragupasta : So on the last image ; i first looked at the reference Jojo gave to us, and looked at the shadows to see how many lights i will need.

My workflow is very simple and basic. I use Mental-ray with Mila materials.

- Get camera angle
- Change the 3D to match the volumes in the ref
- Get environement light that give me colors and ambient light i need
- Add first light and get nice angle
- Add second light
- Create shaders ect
- it's done ! (render setting are just standar MR prefs)

Maybe I could show the process with a video tutorial, but i don't know how to record my screen when i work.

Feel free to check the file

Many thanks FeD.

For screen caputre, Camtasia Studio is a good one (although it is a commercial software)
Camtasia

An open source one is OBS Studio (which you can screen record and even do live streaming from).

Quick First Render. Ill Dive into the Shaders of the eggs and try to hopefully get some more organic qualities to the render.
