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 Open Image Denoise, which transforms noisy images into clean images with machine learning.
输入
- 图像
Noisy image input.
- 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。
- 反照率
可选的反照率渲染通道,以更好地保留细节。对于Cycles,建议使用降噪反照率渲染通道,该通道在启用降噪数据通道时可用。
属性
- 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.
- Accurate
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。
输出
- 图像
降噪图像输出。
