did anybody try DPont's Denoiser Node?

is it worth a go?
got any examples?

i'm wondering to give it a go or not, just wanted to see if anyone has any input...
(well, i probably will anyway... http://irc2go.com/webchat/img/smiley-wink-tongue-1.PNG)

examples are welcome http://forums.cgsociety.org/images/smilies/love.gif

regular render, (50sec)
antialiasing 3, adaptive sampling 0.07

this test is a bit unfair, i could have tweaked it more,
but all-in-all, i didn't think it gave me the results i had hoped for,

if anyone wants to give it a shot, tweak it, the scenefile is attached below
(ps, u "might" get higher rendertimes than me as i used the cache method described in another thread, "Radiosity, animated")

Erikals, did you manage to get this as you wanted it in the end?

I have just started to use denoiser and was wondering how to set it up and what were the best settings.

So basically a Denoiser is a blur filter, but the goal is to blur only the noise,
caused by a sampled occlusion or soft shadows, leaving the edges of the geometry sharp,
by using the depth and the normal info to limit the blurness.

It is more handy to setup the Denoiser node from DP Filter in Lightwave 1.0.x because you get directly both Depth and Normal Buffer
in the Render Buffer node, except that the Normal buffer is flipped (x -1), but this shouldn't be a problem here, in the Image Filter node editor
enable both Buffers, plug them as Depth and Reference Color, Blur Level 2, Sigma 0.2, 5 passes are good common settings (in my sample image
tests on my site) but depends of your noise.

The other problem comes from Texture mapping,
in that cases, two ways,
a mix of Normal and Raw Color as Reference,
or using Denoiser on the Diffuse Shading only
before a final mix with the Raw color.
