Render Elements are a way to break out renders into their component parts such as diffuse color, reflections, shadows, mattes, etc. This gives fine control over the final image when using compositing or image editing applications when re-assembling the final image from its component elements. Render elements are also sometimes known as render passes.

Render Elements are generated at render time based on the ones you choose before rendering. Most render elements have parameters that can be set to customize the render element or its later use in compositing software. These parameters are described on each render element's individual page, along with common uses and any notes on their generation and usage.

V-Ray supports the built-in 3ds Max Render elements user interface. However, V-Ray provides its own render elements and does not support the standard render elements implemented in 3ds Max. Therefore standard 3ds Max render elements will not work with V-Ray, and vice-versa.

For a complete list of render elements, see the List of Supported Render Elements below. All render elements support native V-Ray materials. Some render elements also support standard 3ds Max materials.

Since V-Ray Next Update 1, some of the render elements are rendered differently than before. The Lighting render element now contains all direct diffuse illumination and the GI element contains all indirect diffuse illumination. Similarly, all direct reflections of lights now go to the Specular element and all indirect reflections go to the Reflection element.

Previously this behavior depended on the sampling of the lights and not just on the type of the contribution. Some of the direct contributions that should be in the Lighting and Specular elements were written to the GI and Reflection elements instead. In both cases they compose back to Beauty correctly but the different types of contributions are now split between the elements more consistently.

This change makes the elements more consistent but it's also needed for preventing artifacts in these elements with the adaptive dome light (and possibly in the future with other adaptive lights).

The raw elements are affected only when the corresponding normal and filter elements are available, otherwise they're rendered as before. This is because the raw elements have to be derived internally from the corresponding normal elements in order to work with the consistent elements (f.e. VRayRawGlobalIllumination = VRayGlobalIllumination / DiffuseFilter).

There's an option to enable or disable the new behavior in the Global Switches rollout under the V-Ray tab in the Render Setup window. The consistent elements are automatically enabled when the scene contains an adaptive dome light so they don't have artifacts. They are also enabled by default for new scenes. For V-Ray GPU they are always enabled without an option to disable them.

NOTE 1 – For Standard materials, the VRayLighting element includes the direct and indirect lighting, as well as caustics, while the VRayGlobalIllumination and VRayCaustics elements are black. However, for all materials, adding the VRayLighting, VRayGlobalIllumination, and VRayCaustics elements always gives the total diffuse surface lighting.

NOTE 2 – When an element Enable Filtering is filteredon, it the element is dimmed by atmospheric effects like fog, etc. However, when an element is unfiltered, it is not affected by atmospherics.

NOTE 4 – The channels needed for the denoise operation are automatically generated when the render element has been added before rendering.
