The VRayNoiseLevel Render Element shows the level of noise in the scene. It is the equivalent of the noiseLevel render element generated by the V-Ray Denoiser. VRayNoiseLevel is available as a separate render element for situations where it would be useful on its own outside of the V-Ray Denoiser, such as for manual denoising or debugging purposes.

In this render element, black areas indicate no noise, white pixels indicate a great deal of noise in that area, and grey pixels indicate a moderate level of noise.

This render element is enabled through the Render Elements tab of the Render Setup window in 3ds Max and displays its parameters in a rollout at the bottom of the window:

VRayVFB – When enabled, the render element appears in the V-Ray Frame Buffer.

Deep output – Specifies whether to include this render element in deep images.
