Milk is a funny liquid to get right. Try shining a flash light through a glass of it in a dark room and experiment with the effects.

Some good advice in this thread, I'm sure it will be very useful once I finish studying and start working professionally.

Is bidir/PMC something that is plausible for octane? is it being planned/worked on?

Octane is really maturing, this shit is gorgeous. And it's not even multiple bounce yet!

Fresnel is linked to the Index of refraction for a material. If you have the correct ior, then the fresnel reflections will automatically be correct as well.
Because of this, it could be added transparently for specular materials without adding another slider to tweak.
Fresnel reflections are also a ...

A very interesting paper, one that looks like it will have a large impact on rendering in general.
The base algorithm is post production as long as you have the required passes, but it seems aspects of it could also be incorporated into the original rendering algorithm as feedback for importance ...

Radiance,
Please consider the implementation of fresnel effect on reflective materials. The lack of reflective fresnel effect gives an amateur look to architectural scenes, especially on interiores. It´ll be highly appreciate!
Thank you
Diogo
Another vote for this.
I have asked before but I don't ...

The paper was a great read too.

I expect this will start showing up in games maybe the gpu gen after next, and once it does will be around for a while.
From first glance I don't think it will be possible to increase the number of bounces from 2, but the resolution of the octree can be scaled and ...

Very nice Roubal, I think the metal could look better though, looks kind of washed out and maybe too smooth? I think it needs a darker base colour to give it more contrast.
I love the mottled multicoloured reflections in the ground surface, just beautiful.

Here is my comparison which I think shows both the strength and weakness of the new PMC kernel. Both images were left to converge for 30 mins on a single GTX480.

As you can see PMC does a fantastic job of reducing noise on this difficult scene, however it seems to lack the full degree of colour ...
