次表面散射 (SSS)

此效果是通过在屏幕空间内用模糊漫射光照的方式来模拟真实的次表面散射。

采样

用于计算散射效果的采样数量。

抖动阈值

For the effect to be efficient, samples need to be coherent and not random. This can lead to a cross shaped pattern when the scattering radius is high. Increasing the Jitter Threshold will rotate the samples below this radius percentage in a random pattern in order to hide the visible pattern. This affects the performance if the scattering radius is large.

Note

开启 次表面半透明 选项用于实现光线透过物体表面的效果(类似模拟人耳背面透光)。

此选项仅在附有阴影的光照环境中生效,且无法作用于间接光照。
