I just noticed in the help docs the DMC Sampler adaptive amount has changed from 1.0 to 0.9 [image] Chaos: Industry-leading design and visualization software Chaos develops visualization technologies that empower artists & designers to create photorealistic imagery and animation across …

Vlado mentioned in a few things that having a fully adaptive workflow might not give vray enough initial samples to work with and cause problems. I asked him in another thread what he’d normally leave adaptive amount at and he said he’d never go over 0.9. If you go over it you might be cutting the a…

[image] VFB window unpredictable? Is this correct? why the change? When I wrote the original tutorial, we didn’t have the VRayExtraTex element into which people could plug f.e. a VRayDirt texture. The 1.0 adaptive amount worked well for the RGB image, but it was not enough to get good results …

Yeah right, good to know What about the first pass as brute force, It looks like it introduce a lot of noise in the image, and we have to push the settings really high to suppress that noise, even if we put the brute force at 24 or 64 in subdivision (it help) but it’s still not as smooth as what IR…

24 or 64 might not be enough, as you might find that your anti aliasing is limiting how many samples your brute force actually uses. It’s a problem of using per-pixel / ray traced / brute force GI that it’s making a totally different light simulation for every pixel in your image, so it’s always goi…

I didn’t noticed that so far. thanks for the info.

Well as long as we are going in the Universal Settings, I thought that we shoudn’t use any AA Filtering, so for me it’s just off. I’m using mainly Vraydomelight and VrayIES. For my final renders, I just tried 64 subdiv in bruteforce and 4-12 DMC with noise at 0.005 This give me a descent render b…

Yep - the more max AA samples you give vray to work with, the more the AA sampler tries to do. If you check out the sample rate render element you can get a good idea how many of your min (blue) and red (max) AA samples are getting used in the scene. If you’re using more AA samples than you need, yo…

me too …and totally agree with you, but it helps ..someway :wink:
