I have different issues with the two methods for rendering, both Bucket and Progressive:
Well, the black bucket issue is exactly that. In Bucket mode, I have buckets in a 5K render that simply do not complete. The time estimate on the bottom of the VR frame buffer stops at some reasonable time, but the render never completes the black buckets. The renderer is still running the CPU, chewing on 4 to 10 Buckets that either are black, or have completed some low-res version of the render, but not finished. This is not a problem I have with lower res renders. The problem never shows up at 1/16th res that I use for initial lighting.
In Progressive Mode, the render just never finishes. I say "never" because my time completion estimates for my 5k render (5120 x 3200) are based on a 1280 x 800 sized render, and that estimated time yesterday was 384 minutes. 1/16th being 12 minutes, and I wanted a bit more quality from the noise threshold, so I bumped noise threshold from 0.1 to 0.05, thinking that that change would essentially double the required samples and make the render twice as long. The next morning (this morning), the time estimater at the bottom of the VR FB had stopped at 6.5 hours, but the Render Layer, after 14 hours, had not completed, and I had no idea or ability to estimate how long it might take. Given a looming deadline, I stopped the render and went back to square one to try a better try and estimation for completion.
If you could give me some insights into time completion estimate that would be great. Everyone and all of the stuff I've read says that the three settings, max subdivs, noise threshold and time in minutes should get the render to complete. This is NOT the behavior that I am seeing. It seems like the render wants to complete with whichever of these three settings takes the longest. Unless there is somewhere else I can put how long to take to finish, other than the Max. render time setting under "Image Sampler" in the VRay render settings.
There are plenty of other black bucket pictures in the Forum, and my issue looks just like those. After I post this, I will try to look for a good example in the Forums for you.
Thanks.
