Some of you may have seen the one I did previously in Blender. This one is a more complex/accurate version. Also, I would like to point out that Indigo's aperture_diffraction provided a nice, natural glare on this one. This image has no post-pro at all.

[EDIT] Added the post-pro version (top)...

very nice! how many spp on this one?

About 9,000 and still going actually. I am afraid that it won't clear up much more than it is, though. You can still see some noise around the glare areas...
But I am proud that it is my first non-test render using all Maya/Maya To Indigo!

Extreme glare!

More than clean enough for me. Just go over it with a decent noise filter (NoiseNinja for example) and it should be perfectly clean. Works wonders for me, and it should have no problem at all with that noise.

I like the modelling and glare and everything, nice composition. The background works well too

Thanks! I have don't like noise filters, as they have always done away with the noise, but blurred the image somewhat. I usually use NeatImage Pro when I do use one. Is NoiseNinja better in that regard?

As I said before:
The first scene that shows off Indigo's natural glare without heavy settings-editing.
It even was the opposite, as you had overly much glare before xD

Very nice!

The less noise you have, the less reduction you need and the less blur you'll get

I think, it's clean enough, though.

Thanx Kram. This is just a downsampled version for the forum (800x640). Original size is 1280x1024 - the noise is much more apparent on that one, of course. Also, I have done a little more testing, and found that the aperture_diffraction seems to be attracted to nk mats the most - especially cr.nk

I really like this one, nice job!

Haven't used NeatImage, so I don't know. You will need to do some tweaking to get the best results. What I do is I create a duplicate layer and apply the noise filter to the duplicate. Mostly I don't denoise the luminance channel as much as the colour channel, to keep at least a bit of grain (I don't like images that are perfectly smooth, looks unrealistic somehow). But I only "like" luminance grain, which is a bit like film grain. Anyway, NoiseNinja usually wants to sharpen the image at the same time, I would leave that away first though. Then you erase away the parts of the duplicate where you want to preserve detail, don't like the blurriness etc., you may also set the strength of the eraser to only lessen the effect of the denoising. At the end you may sharpen if you want.
NoiseNinja saves me a lot of rendering time, I think it is very helpful.

Maybe you can show a crop of the noise?

Makes sense:
realistic metals cause realistic reflections, which causes realistic diffraction, I guess

So, under circumstances, every fairly realistic tabulated - spectrum or nk material should give a good refraction

You could try, just for testing, to convert that red to an nk-file, too and look if the diffraction looks different, then

Nice! I like how it shows off the new glare features.

Added post-pro version - see above.

[Edit] And just for kicks, here is a Mental Ray image of the same scene. I wont even tell you how long THAT took... (39 min. 51 sec.) LOL

nice

and
nice

some of you are going to kill me but I have to say that I like the mental ray more then the indigo image (but thats a matter of settings and post pro I think)
