降噪节点

降噪节点用于为来自 Cycles 和其他光线跟踪渲染器的渲染图像降噪。这有助于通过使用更少的样本进行渲染来显著缩短渲染时间。

It is uses , which transforms noisy images into clean images with machine learning.

法向

可选的反照率渲染通道，以更好地保留细节。对于Cycles，建议使用降噪法向渲染通道，该通道在启用降噪数据通道时可用。

Prefilter

• 无

  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.

  快速

  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.

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

HDR

保留 0-1 范围以外的颜色。
