It will take a minimum/maximum value of positive subdivisions and calculate the most effective number of samples needed for a given pixel. In simple terms this is the next step on from the fixed sampler, with the addition of adaptability. This method does not work well with glossy reflections and camera effects such as depth of field, but instead sits well with flat colour, non-reflective objects which are commonly used in architectural visualisation.

By being adaptive in a positive and negative way, Vray can calculate the number of samples needed for areas that are less detailed (undersampling) than more complex areas which require more samples (oversampling). The first word вЂњadaptiveвЂќ means that this sampler can adapt to the scene via undersampling and oversampling. Because of this it is not recommend for interior visualisation but at a low setting it can be useful for preview renders. Negative values are not something to be associated with this sampler.ДЇor scenes that have blurry effects and/or detailed textures, the fixed rate sampler performs best but at the cost of a higher render time due to the amount of samples needed to get a passable result. The more samples per pixel given improves sampling and therefore results in a better quality render. Whereas 4 samples divides the pixel in to 16 (4Г—4). Subdivisions determine the number of samples per pixel, 1 sample is equal to 1 pixel (1Г—1). This is a non-adaptable sampler that uses the simplest method of calculating. Here is a quick explanation of the types of image sampler, again I am not going to go in to much detail as this is not the main focus of this post but if you wish to know more, you will find an in depth explanation on image sampling here. Vray has itвЂ™s own method of dealing with Anti-aliasing and this is controlled via the Vray image sampler (Antialiasing) within the render setup. Aliasing artefacts are generally regarded as jagged edges which are derived from poor, insufficient sampling data.

Typically I render out at 3200 pixels x 2400 pixels for A3 presentation, this is large enough to do any post processing, touch ups and if necessary, it can be adjusted for a larger print by lowering the DPI.ДЄnti-aliasing works to correct aliasing artefacts which occur within the rendered image either by supersampling or undersampling of sub pixels. What resolution do you or your client require? As this largely affects the render settings you decide later on, not matching your output resolution to your render settings can increase your render times unnecessarily.

It is very important to decide early on the render output size as this influences the time allowed for the project. When working with this file type, leaving this on actually increases render times considerably. Another personal reason for turning this off is because I work largely with 3rd party CAD data, specifically Autodesk Inventor 3d files which I import into Autodesk 3ds Max. Under the geometry rollout, by default displacement is ticked by default, rarely do I have a project where displacement is used so I turn this off. You can also turn displacement off (Optional).

This turns off the 3 point lighting system Autodesk 3ds Max has as default, now you have full control over all lights that you add to the scene. In Vray Global Switches, under lighting, set default lights to off. 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. An advanced guide to the interior rendering of still images within Chaos Group Vray and Autodesk 3ds Max.
