Universal V-Ray settings (well, almost)

Re: Universal V-Ray settings (well, almost)

(*) Leave all subdivs anywhere at their default values. They won't have any effect anyways - the 100 AA subdivs will almost certainly override everything else.

I haven't had time to test it yet, but could you please confirm, Vlado, that glossy based speculars will resolve properly even by leaving the settings to their defaults on the materials?
I noticed that raising the subdivs in glossies tends not only to clear the noise, but also to define a lot better the actual shape of the highlight, especially when some anisotropy, or the ward method is used.
Would the AA take care of that too?
Wouldn't it just clean up an "incorrect" result?

Sorry for being lazy

Cheers,

Yep, glossies will be fine and correct. However, this also means that because of the unclamped colors and lack of color mapping very thin hilights may appear somewhat jagged. There is no way around this unfortunately, as it is the correct result.

this is my result using this system. they are awesome i have to say!

This test is with the vray sun/sky system. I had to put the noise to .0001 to get this clean. rendertimes are average of 1 hr/frame.

This is using Debevec's timelapse HDR sequence and the vray dome system. I did not have to get the noise as low. .0005 worked here so the render time is faster naturally at avg of 33 min/frame.

end result is that the gi quality is awesome and man those renders are CLEAN. nice work.

say vlado...
what are the differences between test8 and test9 ?

the rendertime on 9 is much better but the image is cleaner! how what's the scoop?

UAU!
Those look amazing!

very very nice results, Throb.
grats (not like you need any:P)

it looks like there is reflective GI caustics on the wall...could be it

it looks like there is reflective GI caustics on the wall...could be it

but there is also WAY less noise and artifacts in general.
plus the rendertime is much less. i want to know what the scoop is

[dennis]

i mean it looks like reflective caustics in the image that took the longest...as far as i recall it takes forever to calculate...but looks good though

[vlado]

The slowdown is because of the reflective caustics. They could have been done with photon mapping of course, for much shorter render times.

These are great examples that I would love to use to prove my point that while the VraySun/Sky is nice, it cannot mimic the subtle richness and contrast of IBL with HDRs.

Ok where can I find time lapsed HDRI's?
Thanks

Yeap... that is the only one known to mankind. That is because Paul is the only one crazy enough to capture a full day's worth of HDRIs by hand.

Actually... I think he made some interns do it... but still.
