New OIDN 1.4 with new features and better detail preservation

[juangea]

It seems we have a new version, and this time it's not only internal improvements, it brings some new functions to better preserve fine detail with the normal and the albedo, more than what it did

https://github.com/OpenImageDenoise/oid ... tag/v1.4.0

can we have this in 2.6 instead of 1.3? since it's in early development it may be safe to do the change

Ok,now things are pretty clear, we NEED OIDN 1.4 in LuxCore 2.6 ASAP, check this results:

excellent result
perhaps now animations on small samples will not flicker

[juangea]

Not yet, but they confirmed that they are working on temporal stability for future releases for animation

As someone say very often : what a time to be alive !

[juangea]

Yeah!

[patro]

wooooooow..

I have updated the Linux daily builds with Intel OIDN v1.4.0 (other OS will follow) and added the support for auxiliary buffers pre-filtering.

This is a 32 samples/pixel rendering:

and this is the denoised version without pre-filtering:

This is the Albedo AOV before pre-filtering:

and this after pre-filtering:

and this is the denoised version with pre-filtering:

To recap, without pre-filtering Vs. with prefiltering:

This isn't a practically good test scene to highlight the difference but I would say the improvement is there.

Due to the capability to pre-filtering the Albedo AOV, it may worth re-evaluating how albedo of specular surfaces is done (i.e. glass, mirror, etc.).

[juangea]

Yep, the improvement is there, and yes, Albedo with glass and reflections would be very welcome.

Maybe you can create a new Denoising Albedo, like what Cycles does, so the original Albedo remains untouched as it is correct.

I agree that this scene is not the best candidate for this, I have a few scenes with small Albedo detail, as soon as this is available in BlendLuxCore I will test with our scenes
