U want to try setting this more like 4/25/005, see if that makes any difference. To be honest, I can’t make out anything you have in there though. Let me see if I can explain this correctly and if myself have this right:
You don’t have enough samples going in that direction. So you can increase sampling to a million, but you still don’t have enough being added to that area, because VRay does not consider you need any there. Hence, my option for putting Min of 4 instead of 1. That means everywhere you will get an increased sampling, hence my option for bringing the Max down to 25. You may need more, but I think that may be enough and my reason for bringing Noise to 005 is because you are only bringing it down to 003 because you are trying to clean it up, but you can’t since you don’t have enough samples being sent in that direction. Anyone else to add if I’m in err somewhere here.
ALso try limiting secondary ray intensity, enabling sub-pixel-mapping and clamping, and try another AA filter like cubic or quadratic
try to DISABLE subpixelmapping because it seems to have issues in builds lower than 3.3.03…
what does the renderelement samplerate mean? is it blue or red?
best regards

Max Ray Intensity up or down? The default being 20.
I’m on 3.3.05. The sample rate is red, however, nothing I do changes that. I can go 100/.003, and it is still red.
Why of course. That means there is not enough samples to cover your noise threshold. Try making the min 4 and the max 25. Get your noise to be at .005 and see if that makes any difference.
Bobby, also seeing your set up and with a Titan X as a GPU, don’t you want to try VRay RT with Cuda enabled? For the past two weeks it is all I’ve been using and it is not only faster, but cleaner and simpler to use.
That is one crazy samplerate pass…
Do you look through some strange glass maybe? Do you have atmospheric effects enabled with some strange settings? Some crazy post processing or sharpening filters active?
Just V-Ray defaults, with the tweaks suggested. Pretty simple space with and HDRI and V-Ray camera. Nothing changes with V-Ray Sun/Sky, so it’s not the HDRI.
With my GTX 970, I just get a memory error when using Cuda.
That must be one hell of a scene. I personally would like to take a look at it. Not sure what’s making it so. Cause if it errs due to memory, then there is something wrong with your scene or materials. And like he said below, that’s one hell of a sampleratepass for those settings. Curious, does IR work any better on this scene?
I tried IRR last night and after 7 hours, it looked awful. V-Ray RT GPU looks good, so I’ll let that run for awhile.
What’s it like with a grey override material on everything but the glass and what’s your shade rate at? How come you’re using colour thresh of 0.003?
Material override is still grainy. I dropped the color thresh down to try and counter the noise. Here is the file, which might take a little to synchronize.

All finished?
Yes, it has synchronized. About 30 min. in Progressive mode is already returning better results.
Ill throw it on my RT box tonight to see how it goes, I have two 780 TI’s on that one that seems to be pretty fast.
Cant use my office farm tonight as we are moving buildings so that one is down till no later than Monday hopefully.
Awesome, let me know how it goes.
