Autodesk 3ds Max

Overview

Starting in Vray 1.5 the settings have been seperated into 3 Tabs. Here you will find a list of every setting within these tabs. You will also find links to each setting, and how they effect the final rendering.

Vray Authorization

Here you will find the licensing information and authorization settings for the Vray license system. The Vray license uses a floating license server that is tied back to a hardware USB dongle.

Vray Frame Buffer

In addition to rendering to the 3ds Max Rendered Frame Window (RFW or VFB), V-Ray allows you to render to a V-Ray specific frame buffer, which has some additional capabilities:

• Allows you to view all render elements in a single window and switch between them easily;
• Keeps the image in full 32-bit floating-point format;
• Allows you to perform simple color corrections on the rendered image;
• Allows you to choose the order in which the buckets are rendered.

Vray Global switches

The global switch roll out allows for various global changes to be turned on or off.

Vray Image sampler (antialiasing)

In V-Ray, an image sampler refers to an algorithm for sampling and filtering the image function, and producing the final array of pixels that constitute the rendered image.

V-Ray implements several algorithms for sampling an image. All image samplers support MAX's standard antialiasing filters, although at the cost of increased rendering time. You can choose between Fixed rate sampler, Adaptive DMC sampler and Adaptive subdivision sampler.

Vray Adaptive DMC image sampler

Monte Carlo (MC) sampling is a method for evaluating "blurry" values (anitaliasing, depth of field, indirect illumination, area lights, glossy reflections/refractions, translucency, motion blur etc). V-Ray uses a variant of Monte Carlo sampling called deterministic Monte Carlo (DMC). The difference between pure Monte Carlo sampling and deterministic Monte Carlo is that the first uses pseudo-random numbers which are different for each and every evaluation (and so re-rendering a single image will always produce slightly different results in the noise), while deterministic Monte Carlo uses a pre-defined set of samples (possibly optimized to reduce the noise), which allows re-rendering an image to always produce the exact same result. By default, the deterministic Monte Carlo method used by V-Ray is a modficiation of Schlick sampling, introduced by Christophe Schlick in 1991 (see the References section below).

Vray Environment

The Environment section in V-Ray render parameters is where you can specify a color and a texture map to be used during GI and reflection/refraction calculations. If you don't specify a color/map then the background color and map specified in the 3ds Max Environment dialog will be used by default.

Vray Color mapping

Color mapping (also called tone mapping) can be used to apply color transformations on the final image colors. Sometimes an image can contain a higher range of colors that can be displayed on a computer screen. Color mapping has the task of re-mapping the image values to be suitable for display purposes

Vray Camera

The camera rollout controls the way the scene geometry is projected onto the image. Note that if you use the VRayPhysicalCamera in your scene, most of the parameters in this section are ignored, with the exception of some of the motion blur parameters (those on the right-hand side of the dialog),
