What is V-Ray DMC sampler?

What is V-Ray DMC sampler?

The DMC Sampler is a framework within V-Ray for determining exactly which samples are to be taken around pixels involved in “blurry” effects such as anti-aliasing, depth of field, indirect illumination, area lights, glossy reflections/refractions, translucency, motion blur, and so on.

What is image sampling in V-Ray?

In V-Ray, an image sampler refers to an algorithm for calculating a pixel’s color based on the colors within and around it. Each pixel in a rendering can have only one color.

What is image filter in V-Ray 3ds Max?

Image filter – Enables sub-pixel filtering of materials. When this option is disabled, an internal 1×1 pixel box filter is used. All image samplers support all 3ds Max’s standard anti-aliasing filters except the Plate Match filter. Using filters increases rendering time. Filter – Specifies the filter type.

What is noise limit in VRAY?

Noise limit – A threshold that determines when to stop refining a pixel. Higher values allow more noise in the image, while lower values try to reduce the noise. A value of 0.0 traces the entire image unconditionally.

What is anti-aliasing V-Ray?

One of the functions of image sampling is anti-aliasing, which is the reduction of jagged edges in a rendering.

Why are my VRAY render grainy?

For example, if you are rendering an interior shot that is lit with sunlight, but do not have enough windows to let the light through, then the image will look grainy. Also, if you are using artificial lights but their intensity is too low, or the number of lights is not enough, then again the image will look grainy.

How does DMC sampler work in Vray?

First thing that we need to know, and it’s a very important feature of DMC sampler, is that complete pixel information surrounding pixel that VRay is sampling is taken into consideration when deciding if it needs to oversample that pixel or not. Result of this is shown in the image we already saw, where I showed you a teapot with thin lines.

How do I reduce noise in V-Ray?

So in order to reduce noise, you need to provide V-Ray with more information – and to provide V-Ray with more information, you need to take more samples. The amount of Primary Samples sent out into the scene is mainly controlled by the Min Subdivs, Max Subdivs, and Color Threshold settings of the Image Sampler.

The samples controlled by V-Ray’s Image Sampler (also known as Anti-Aliasing or AA), which is specialized in sampling a scene’s Geometry, Textures, Depth of Field, and Motion Blur.

What does Max DMC mean in Vray?

The reason for that is that if you set Max DMC to 50 (for example), Vray will subdivide every subdiv value in the scene to 1, which means for every ray sample sent to the scene you will be sending only 1 glossy sample for reflection, 1 for area light, motion blur etc.
