OctaneRender™ 2019.1 XB1 Tweet

Look at this, some kind of white dots on a Diffuse material-
it's that same sphere scene I was doing with Displacement, except I made the Blue Sphere a plain Diffuse Sphere.

For some reason, adjusting the Roughness and Specular amounts on the yellow sphere (which has glossiness) produces corresponding white dots on the Blue Sphere (which is Diffuse, with no gloss).
I see it gets the yellow GI from the Yellow Sphere, which is expected, but why the white dots?

It is Diffuse, I say!....
Such indignation!...
I dare say Octane-V2 would probably be spinning in its grave if it would hear of such mischief!...

But, weird thing too is that if you raise the render target's Max Samples (ie from 50 to 1,000), it produces **more** dots, where you might think it would have resolved them.
Play with the Yellow sphere's Specular and Roughness, and watch the white dots respond on the diffuse Blue Sphere.

THX again!

[Notiusweb]

in the slides video, right before it goes to XB2 stuff, it shows 4x Super Sampling.
Is this currently in XB1, and if so, is it on by default? Does it turn on and off?

Thx!

Look at this! DXR on non-RTX in April!

Really like playing with the new displacement.

Spent the day building a fully procedural cliff and ocean.

Here is a difference between the Old 2018 Denoiser and the New 2019 Denoiser.
Same exact scene, as in same file, settings...

Same file, created in 2018, with Denoiser in both at 0.163 Blend, 55 s/px

Apparently the 2019 denoiser is hitting the image harder, affecting detail differently and introducing artifacts compared to what you would have got in 2018.
Look at skin in 2019 (less detail than in 2018) and above eyes (white dot artifacts in 2019 that were not present in 2018).

2018

2019

So it is not identical if you open a scene from having denoised in 2018. You might have to increase amount on the blend slider to get what you would have otherwise got in 2018.
Maybe fluffy volumes render faster yes, but at a cost to other stuff being denoised.

Here is a simpler Denoiser difference scene, using a Vectron.
Open in 2018, and then open in 2019 if you want to see:

You get this in 2018

And with same denoiser settings, get this in 2019

It's not the detail that concerns me, it's the pink Transmission twinklets in 2019 that almost appear to be 2019-Denoiser artifacts.
(And no, I can't hot-pixel them away, they are still there.)

If I understand... 2019 is using the new update of Nvidia Optix. The Optix uses AI, which learns over time. So I think we should be cautious to make conclusions about the new Optix and Otoy’s new deployment of it...at such an early stage. How the de-noising performs is likely to change as Nvidia tweaks API and as new version "learns."

Optix?! That means MDL in Octane!!!

This is great work, Rohan. It looks like you had a fun day! So I suppose that you built this from just two planes and all the magic is done with materials featuring displacement?

And since I'm very shamelessly asking for stuff, can we have custom bokeh shapes. Pleeeaaaseeee

You can use the aperture texture. Create a black and white mask of the shape of the aperture, where white is passthrough and black opaque, and set it as the aperture texture. Think of it as a cardboard cutout you would place in front of the lens. The bokeh will take that same shape. Use projection mode "OSL delayed UV" on the texture.

it would be cool if we can use colored aperture textures for create aberration effect.
