Splothces and more

can i test that out by using the global overide for a vray mat?
NM....light doesnt shine through windows...LOL
NM again....just turned them off....still prepassing now....

technically yes, but better to just save out as different version and then apply gray map to everything so that there's no mapping errors. Be sure to clear your mat editor and make all slots default mat or something.

EDIT: Dont worry about the glass, it can be set to ignore for lights?GI or even just hidden/deleted.

Here is the link. Thanx all...Splcthes still there....

says file unavailable at moment. Try uploading it to rapidshare was well.

[EricCamper]

oops....it just worked for my buddy.....try again....and I will also post to rapid

Downloading now....

Can you try these settings and post the image?

Adapt QMC, Min/Max 2/5, disable 'Use Noise Thresh', Clr thresh=0.005 (you really need to consider switching from Adapt Sub because you have too many areas of fine detail that you are blurring together with subdivision)
Ir map preset of Med, HSph Subdiv=20, Interp samples=80
Light cache subdivs=1000, Prefilter=off, Filter=Nearest and 10
Noise thresh=0.01 (this was set way too high)
Disable displacement (don't know where you have displacement used)

BTW, bravo trying to make this work with the vray camera...that certainly makes things more challenging but if you can make it work good job.

its really because its such a high contrast scene.. interior lit with the sun/sky system at full power will do that. I had similar problems in the past when using for instance, light-materials.. since the light is all indirect, the renderer isn't 'biased' towards finding where the hot spots are until after it already starts to cast rays. its more difficult for the renderer to balance out the color/luminance values from one sample to the next.

since just about all of the light is coming from the two windows, if at one point on the floor the *random* sampler shoots say, 15 rays that hit the window out of 100, and the rest hit comparatively *DARK* areas of the rest of the room, lets say arbitrarily that that sample has a brightness value of 16 averaged.

say, theres another sample on the floor, and it shoots out 100 rays also.. but this time, thanks to our friends quasi, monte, and carlo, the rays only intersect with the bright part 3 times.. and the rest hit the *DARK* rest of the room. giving it an arbitrary brightness average value of 5.

so from one sample to the next, the main target needed is a very tiny area that is providing all of the light, and the samples taken don't know that the light is there until after they send out their rays to seeee! same problem you used to have with lighting a scene via HDR before vlado so kindly let the vraylights have importance sampling

basically what I'm saying is that the ambient bounced light in the room is almost negligible in the mount that it adds to the light from the SUN. so in a very high contrast scene. (you know its a ridiculously high contrast scene by the need for your burn value in the Reinhard to be .12.. meaning to keep things from blowing out, you are scaling the whites down by 90%)

well, that wandered off track a few times, but hopefully someone gets something out of it

btw...the reason you still have an aliased look to the image is because of the clr thresh value with the adapt subd image sampler....if you drop it to something like 0.01 you should see huge improvements. but as i said, i really think you should consider adapt qmc

trying those settings now Brian....will post some results....Just had a meeting with a client......"I really don;t care how much it costs....as long as we get it by September...." That was his exact words.....I love him....I may put him in my will.....

Hahaha, THAT is funny!
