次表面散射 (SSS)

This effect mimics real subsurface scattering by blurring the diffuse lighting in screen space.

Number of samples to compute the scattering effect.

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

Subsurface Translucency needs to be enabled in order to make the light go through an object (like simulating a human ear lit from behind).

This option only works with shadowed lights and does not work with indirect lighting.
