About Adaptive Light setting.

[anthonyh]

Hi,
sorry if this has been asked, couldn`t find anything.
Considering Adaptive lights turns off clamp and sub-pixel at render time what happens when Adaptive Lights is turned on for a scene where there are less than the specified number of lights to adapt for ? eg. just a sun and dome. Does it actually do anything ? and if not should the clamp/sub-pixel settings be respected instead of being overwritten since (potentially) no benefit would be achieved for using Adaptive lights. Also should it then fall back to probablistic or full evaluation maybe ?
I noticed this because I loaded an outdoor scene set up in vray 3.4 and defaulted to adaptive lights in vray 3.6 and then rendered without clamping etc.
Maybe vray could load the existing setting rather than resetting to adaptive for legacy files ? The original file was set to probablistic.
thanks

Yes, it still does things even with fewer light sources.

I'm considering a few alternative implementations for the subpixel output, so hopefully it will be back soon.

Best regards,

Good to know, thanks Vlado.

Do subpixel mapping and clamp output have any sense these days? I thought they were outdated since the introduction of maximum ray intensity and the like.

For me they do. I don`t always have the luxury of time to fix jagged edges from overbright light/reflection in a scene, Click on clamp/sub-pixel and I can go home and have a beer instead. The client doesn`t care about this or even know what I`m on about why it takes longer to sort it. Not sure I`ve seen Max ray intensity affect anything of significance on this issue.
Honestly I`m all for all for it when there`s only 1 button left in Vray that says `RENDER` and no options to see at all, but it would have to render quickly, noise free and flicker free for animation and have no issues at all with anything, working totally automatically with any situation you throw at it. It`s rather unlikely but I`d honestly support it. Until then, Lay off my `easy mode` !

cheers
