Having said that, V Ray is very consistent, from your screen shot you still have 10 minutes max to render. Progressive rendering, is not my fav honestly, besides for those large images, it will use more memory than bucket rendering. This comments goes to Brittany not Alfred If you choose to use bucket sampling, then time get out of the equation obviously. Just be careful of copying setting from the internet, most of those tutorials are outdated or are configuration to old version of VRay (VRay 2.x) from 3.x you should not mess around with samples anymore, just adjust your maximum sampler, noise, time and that's all. If you really know what you are doing, you can make it work faster, if you don't and just change random settings, everything will slow down and it won't give you the results you hope. VRay 3.4 by default should have less control to move and just let it work alone, no more worries about materials and lights samples. If you don't understand how the whole sampler work, I would leave local subdivs unchecked and let VRay do it magics.
For that large image, I would just set the time to zero and let it cook until get the 100 passes.Īs a side note, I don't know how well you understand VRay, but I noticed you have 'use local subdivs' activate, if you know what this mean, then adjusting your maximun sampler would be recommended.
