We even set Option 1 to have a lower noise threshold, yet it still turned out noisier than option 2! Most likely, in version 3. We also hope that all important aspects of global quality and speed settings are clear. What does that mean? As a general guideline:. This represents a simple graphical way of describing how DMC handles subdivision of glossy values in the scene. If adaptive amount is set to 0. It has huge amount of small details and most of the raytracers can't handle sampling of hair in efficient and fast way. The main issue is whether we really need to waste hours locally reconfiguring each material, the light source in the scene, and the GI rendering algorithms to affect slightly and sometimes not slightly the rendering speed. The higher the noise threshold value, the more severe will be the difference considered as the basis for early termination of calculation, and, consequently, fewer samples will be used for rendering blurry effects.
Settings to use for both draft and hi-quality renders. Use DMC sampler threshold Render and make sure gamma preview is ticked in the vray frame buffer.

The settings for the DMC sampler are located in the Global DMC rollout. are very different, then a larger number of them will be necessary to get a good result. UI Path: ||Render Settings window|| > VRay tab > DMC sampler rollout Controls V-Ray's judgment of when a blurry value is "good enough" to be used.
Identifying Sources Of Noise. This parameter specifies when to use the so-called early termination technique.
So lets first try what most people usually do to get a high quality low noise render - adopt the so-called 'Universal V-Ray Settings' and let V-Ray take as many Primary Samples AA as needed to eliminate the noise. In our Baseline Render, we saw that while the edges of objects looked clean and defined, the noise seemed to reside primarily in the reflections and shadows.

VRay DMC Sampler
render settings, render will decide that. But before we jump to DMC sampler examples let's go over VRay DMC Sampler tab and. A tool to demonstrate the math behind VRay's Image Sampler and DMC Sampler. Simply input your V-Ray settings and the calculator will show you the. and added a note about GI controlling VRayHairMtl's reflection/refraction quality.

Many times you'll see artists adopt the 'Universal V-Ray Settings' of having the The samples controlled by V-Ray's DMC Sampler, which is specialized in In this tutorial we'll learn how to best utilize these Primary and.
In this simple example you can see how lines are cracked, not enough samples are cast into areas where needed, and only because adaptive subdivision sampler is basing it's decision to sample more on information it gets from edge of pixel.
To get the up-to-date interface manual for your software, please refer to the official documentation. It basically doesn't know complete color information of surrounding pixel, it only knows what's going on at the edges of those pixels.
Later on if you're interested in learning more about how V-Rays internal formulas work - you can check out the DMC Calculator I've coded - but for right now it's not necessary. For example, the V-Ray developers are removed the Fixed and Adaptive subdivision image sampling algorithms from V-ray.
