At this point you can also tick split render channels and point to the location where you want to save your render passes. The Vray Frame Buffer has some key additions which will help you finalise your render. In the Vray Render Setup go to Vray frame buffer and tick enable built-in frame buffer and leave the other settings as they are.

I also use the Vray physical camera, information on how to set the camera up correctly can be found here.

You can find an easy to follow step by step guide here. I strongly recommend setting this up as it will improve many areas within your workflow. This guide is a summary of all those different techniques, and it will give you rendering settings that work well for interior visualisation as well as the reasons behind them.Д«efore I start, I would like to point out that I will be using a linear workflow with a gamma 2.2 setup within 3ds Max and Vray. There are many other guides out there that offer similar and different approaches to Vray rendering but I have found some techniques to be somewhat confusing and hard to follow. But there are steps you can take in order to get close to what you need for the majority of interior visualisation. Most will argue that there are no вЂњuniversal settingsвЂќ for Vray and I tend to agree. I like that the universal one retains all the detail round the door without getting muddy, and in general shadows look better defined.An advanced guide to the interior rendering of still images within Chaos Group Vray and Autodesk 3ds Max. (My attitude to render times is that if they are too high, it means I need to buy an additional workstation.) Here are the 2 renders at 1600x900 pixels, by all means use whichever GI solution suits your needs. As I work solely with high res stills, I'm mainly interested in visual quality. Someone on twitter asked me to clarify why I prefer the universal version of the HDR sky render over the irradiance map version. Adding the render times on the images is just so that we can compare one method with another method, I'm not trying to fool anyone here! For the render times for one workstation just double the stated render times. I never do animation work so have no experience with having to output super clean renders so please bear that in mind in the comments.ДЄll images here were rendered at 1024 x 576 pixels, but on TWOВ dual xeon workstations. When I do high res renders, like over 5k, I sometimes even increase the noise threshold to 0.02. The renders are just for comparison purposes. then I would just change the noise threshold from 0.01 to something lower. I suspect this was because the Min Shading Rate was already optimising things as far as they could go.ДЇor people thinking that the above renders look too noisy for their uses. HDR Domelight subdivs: In the past I have had success with changing the subdivs of the domelight, but for brute force with this scene it didnt make any difference. Secondly I enabled EMBREE as my processors support it for an extra reduction in render time. See blog post on Universal Settings in VRay 3.0 for more info. 6.ДЇirst off I set the Min Shading Rate to 6, which made a huge difference. This is maybe a bit of an old skool trick to try and encourage faster render times, but as demonstrated above it might not be much faster and it loses a lot of definition in the shadows.

The scene I was sent had a low res copy of the HDR sky in the vraydomelight, and a full res version in the environment override slots in the vray settings. Universal Settings uses Brute Force for primary GI and Light Cache for secondary GI, if you are unsure how to set it up, take a look at the vray help files section on Universal Settings.Д¬larification on my HDR setup: I always use just one full resolution HDR sky in a vraydomelight to do all lighting reflections etc. I will switch to Irradiance map later on to show how it compares. Of course it takes a lot longer to render, but it will help me to optimise the scene. I prefer working in vray universal settings mode, so to do most of my testing I am switching over to that set-up. There were a couple of things I changed right away: 1.Дisabled bitmap paging In some versions of 3dsmax/Vray it seemed to slow things down, so I always disable it. The first step is to figure out what is going on in the scene, and to render it as opened. I haven't used anything but a HDR sky lighting set up (interiors & exteriors) for about 4 years so thought I would try to answer a lot of the questions here.ДЇewlo from the chaosgroup forum has kindly allowed me to use his interior as an example. I get a lot of emails from people asking how they can use my HDR skies for arch viz interiors and if it is even advisable.
