Looks really good!

busy times, was really hoping apple would release an egpu on usb-c last week :) , so I did some sketches on internal parts like the new pascal/polaris chips, power supply and heat dissipation
We could really use something like adaptive sampling for these kind of texture emitters and .ies lights that just take way longer to clear up

worked a bit on the specular part and colour, getting there


Really really cool!!! I've to made some ceramic products and I'm working on a nice material like this! Could you share some secrets about this? :D :D :D
Thank you! Enjoy!

hi! yes i`ll look into it when i have more time. it`s a combination of glossy, diffuse and specular in standalone!
the sss pass helps to quickly see how light refracts through it, but renders slowly

Here`s another take on glass, rendered roughly twice the size and resized, 12 hours overnight on pt on a single gtx580, and one from a while ago, IKEA manual led torch

another shot on glass and procedural noise, around 13h on a single gtx580

Hi guys,

As a part of renderproject we made a small benchmark scene, I used internally.
Classic Pixar teapot and a scene pathtracers don`t really like..small caustics as well.
We tune the GI_clamp and see what it does to the noise and shadows, same goes for Caustic blur.
Eventually import them to max or cinema, to get a grip on material node structures.

Rendertime for a clean image on Octane 2.24.1 1X GTX580, Render priority off:
Specs:
1920x1080
Tris: 82376
Pathtracing at DD16 - SD24
Caustic blur 0.01
Coherent ratio 0.5
GI clamp 1000000
Camera: Set to Linear, gamma adjusted to 1.445
Highlight compression 1

Max samples to clean out Main Beauty pass: 25000 samples in 90 in minutes
Max samples to clean out Light pass 1: 200k samples 11h 22m
Max samples to clean out Light pass 2: 200k samples 11h 22m

Moreover, you can check out materials for:

- Procedural noise that you can further edit for custom maps
- Gradient emmissions for softer lights, mixed material, sinewave textures
- Gradients in glass
- Studio HDRI with an upper Lightbox

I`m instructing the scene this weekend, then it`s available for free!
Perhaps a derived version with more smaller emitters is an idea too.

Very nice! Will you be sharing the scene as orbx - I'd like to play with it in the standalone.

Here we go! Only suited for Octane 2.24.1 and above.
