Generally V-Ray samples the HDR dome efficiently to make sure that IBL produces as little noise as possible. This type of image-based environment lighting has been a staple in CG rendering for years.Īlthough image-based lighting has improved over the years, it still involves a lot of sampling, especially for interior scenes. A dome light is a spherical or hemispherical light that is often paired with a high dynamic range image (HDRI) of the environment. V-Ray’s smart sampling of lights have now been integrated into the dome light and image-based lighting. There are more smart features coming in the next V-Ray, like automatic camera exposure and white balance, but the first one to talk about is the new Adaptive Dome Light in V-Ray Next for 3ds Max. Also, a new improved Adaptive Lights 2 technique is coming in our next release (more on that later). This makes it possible for users to render scenes with a large number of light sources, without affecting render times.

It’s smart enough to produce even noise levels throughout the image, placing more samples in areas with more noise, without oversampling other areas that don’t need it.Īnother example would be V-Ray’s Adaptive Lights algorithm which learns about the scene by analyzing the Light Cache data to determine which lights to sample and which ones to ignore. V-Ray's analysis results in a faster, cleaner render.įor example, with the introduction of Variance-based Adaptive Sampling we eliminated the need to set individual subdivisions on materials and lights, or even camera effects like depth of field.

In the same way that machine learning makes choices based on what is learned about a specific problem, V-Ray has been adopting learning techniques for analyzing a scene as it is rendering. That’s because we’ve put a lot of effort into making V-Ray smarter. In fact, many of our users have discovered that their old scenes typically render faster and cleaner, simply by removing their previous settings and switching to the new defaults. You may have also noticed that V-Ray has gotten much faster by default.

Since the release of V-Ray 3.0, you may have noticed that many of the updates have made it possible to render better without tweaking settings.
