Denoise Node

Denoise Node.

The Denoise node is used to denoise renders from Cycles and other ray tracing renderers. This helps to significantly reduce render time by rendering with fewer samples.

It uses Open Image Denoise, which transforms noisy images into clean images with machine learning.

Ingressi

Immagine

Noisy image input.

Normale

Optional normal render pass to better preserve detail. For Cycles, it is recommended to use the Denoising Normal render pass, which is available when enabling the Denoising Data passes.

Albedo

Optional albedo render pass to better preserve detail. For Cycles, it is recommended to use the Denoising Albedo render pass, which is available when enabling the Denoising Data passes.

Proprietà

Prefilter
Nessuno:

Does not apply any prefiltering to the input passes. This option retains the most detail and is the fastest, but assumes the input passes are noise free which may require a high sample count. If the input passes are not noise free, then noise will remain in the image after denoising.

Fast:

Assumes the input passes are not noise free, yet does not apply prefiltering to the input passes. This option is faster than Accurate but produces a blurrier result.

Accurate:

Prefilters the input passes before denoising to reduce noise. This option usually produces more detailed results than Fast with increased processing time.

HDR

Preserve colors outside the 0 to 1 range.

Render before and after denoising, with a very low number of samples as input. As more samples are used, the denoiser will be able to better preserve detail.
