Setup a raw lighting pass, Specular pass and sample rate pass. Setup your Min Shade rate, default is 6 and this work for most scenes, since your scene is interior and has no height frequency objects ( fancy way to say small pattern object such gills or grass) then you can increase this number to 8 or 10. Check how many lights you have in scene, if they are more than 16 change that number in to the 'Probabilistic light' slot, let say you have 8, then you are cool no need to adjust anything, if you have 100 then put that number there. Set light cache about 1500 or 200 if you feel fancy, for your scene 1500 will be OK. First bounce Brute force (or irradiance), Second bounce Light cache. That's the 'magic' of V Ray you can control always quality Vs time. If you want to be sure that uses all your 100 passes you can setup your threshold to 0 but it will take a long long time to render because it will calculate 100 time for each pixel in your scene. You can give 100000 passes but if you setup 1 threshold value, it barely will use any, maybe 10, depending. VRay will take two pixels and compare how dark or bright they are, if those pixels are within the 0.005 threshold of color difference it will clean them or it will skip it. how I know how many samples should I use? I have all this samples to clean the image, This is independent of the time. As I recommended earlier set the time to Zero (0) and keep the 100 passes or set it to 150 and just let it cook, depending of your computer it may take a while, this is normal for large image, if you need faster renderings I would recommend to use distribute rendering. 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 Just be careful of copying setting from the internet, most of those tutorials are outdated or are configuration to old version of VRay (VRay 2.x) from 3.x you should not mess around with samples anymore, just adjust your maximum sampler, noise, time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.
