# 次表面散射 (SSS)¶

## 属性¶

Is an approximation to physically-based volume scattering. Gives less blurry results than Cubic and Gaussian functions.

Cycles Only Provides the most accurate results for thin and curved objects. This comes at the cost of increased render time or noise for more dense media like skin, but also better geometry detail preservation. Random Walk uses true volumetric scattering inside the mesh, which means that it works best for closed meshes. Overlapping faces and holes in the mesh can cause problems.
