Sub-pixel ON-OFF : phisical INCORRECT, noise and rendertime

[cecofuli]

Morbid, ohh, yes, yes! It's in my TO DO list. But not this project. Now it completed. In the next I would like to try a different renderer. But, as Vlado wrote, form this complex interior (all glossy wall with tiny specular map, many indidect light, VRaylight inside a complex glass lamps, sub-pixel mapping OFF etc...) the solution is to wait the next V-Ray Brute force progressive rendering.

Since your interiors are probably one of the most complicated i've seen, it would be nice to try them with something like maxwell and see how it holds up. Soon though its all gonna be RT...just a few more years of wait

If you want one of my scene, I'll send you. Tell me if you have some preferences ))

haha...I've looked at your scenes before and in my opinion they are setup verywell, Im not sure what I can do to improve it. Converting it to another render is a long task for just a simple test...But maybe worth it? I don't have the newest gpu hardware so it will be pointless to try it, only with RT cpu.

My preference would be in maya! everything in maya!

When I have time, I would like to do. Maybe with this scene =)

Hi Cecofuli,

Like you i struggle a lot with these render times and noise when sub pixel and clamp are off.
I obtain the best result when i clone all my lights: the first light is set up with a big intensity but it is only affect diffuse, the clone light is set up with a very low intensity but it is affect only specular( and eventually reflection).
I do that because i noticed that often noise and very long render times are caused by lights with big intensity with affect diffuse, specular and reflection checked.
With my set up, i find that the lighting is much more natural( without these very very bright dots wich are so long to render), and a lot faster.
Perhaps it could help you.

Hi Dam,
nice tricks, but... I would like to prefer a "real world like" solution... I want to try with PT (LC+LC) and see what happen...
But, as some other competitor do right now, in my opinion the solution will be a Path Tracing (or any progressive render) as primary bounce and LC for secondary... Like Vlado wrote some messages ago.
