Hide denoiser element – The VRayDenoiser channel is not present separately in the VFB. The information calculated within them is not applied to other render elements, and no VRayDenoiser Render Element is generated. Only generate render elements – All render elements required for denoising are generated so that denoising can be done with the Standalone Denoise Tool or the V-Ray Denoiser plugin for Nuke. Mode – Specifies how the results of VRayDenoiser will be saved. It also doesn't support cross-frame denoising and will likely produce flickering when used in animation.Įnabled – Enables the render elements to appear in the V-Ray Virtual Frame Buffer.ĭeep output – Specifies whether to include this render element in deep images.įilename suffix – The text added to the end of the rendered file, when saved as a separate file (e.g. This means that there will be differences between the original RGB image and the one reconstructed from render elements that are denoised with the NVIDIA AI denoiser. For example, the NVIDIA AI denoiser performs the denoising faster, but is not consistent when denoising render elements. This means that rendering on the CPU will still require an NVIDIA GPU for denoising with the NVIDIA AI denoiser and has some advantages and drawbacks compared to the Default V-Ray Denoiser. The NVIDIA AI denoiser requires an NVIDIA GPU to work, regardless of whether the actual rendering was performed on the CPU or GPU. NVIDIA AI denoiser - V-Ray's integration of NVIDIA's AI-based denoising algorithm. In addition, it comes with a Denoiser Tool, which is recommended for denoising animation by using frame blending. This means that it is recommended for denoising the render elements to be used for compositing back the beauty image. It is consistent when denoising render elements, as it applies the same denoising operator to all render channels. It can utilize the CPU or the GPU (AMD or NVIDIA GPUs) to perform the denoising. Each offers a different denoising algorithm that comes with different benefits.ĭefault V-Ray denoiser - V-Ray's denoising algorithm. VRayDenoiser offers a choice between the Default V-Ray denoiser, the NVIDIA AI denoiser and the Intel Open Image denoiser. Whether this render element is generated depends on the Mode selection. The VRayDenoiser render element, when generated, contains the final image that results from noise removal.The defocusAmount render element is non-black only when depth of field and motion blur are enabled, and contains the estimated pixel blurring in screen space. The noiseLevel render element is the amount of noise for each pixel in greyscale values, as estimated by the V-Ray image sampler.Parameters can also be adjusted directly by using the Custom preset. The V-Ray Denoiser has three preset options for its settings: Default, Mild, and Strong. See the Denoising Engines section for more information. There are three denoising engines to choose from - the Default V-Ray denoiser, the NVIDIA AI denoiser (V-Ray's implementation of NVIDIA's AI-based denoising algorithm) and the Intel Open Image denoiser (V-Ray's implementation of the Intel® Open Image Denoise). Images can also be denoised using the Standalone Denoise Tool included with the installation of V-Ray for Maya.īecause the V-Ray Denoiser operates on other render elements (like RGB_Color ) rather than being part of the rendering process itself, the denoising operation does not require re-rendering of the scene. The denoising operation detects areas where noise is present and smooths them out. The V-Ray Denoiser takes an existing render and applies a denoising operation to it after the image is completely rendered out via normal means.
