Subsurface scattering data is view-dependant which means that it has to be re-generated when either the camera or any objects move. It also has to be regenerated if lights change (position or intensity) and if materials are adjusted.

Subsurface Scattering. Subsurface Scattering handles light that penetrates and moves within the area under a surface. Use it to make organic materials, like skin, look smooth and natural rather than rough and plastic-like. HDRP implements subsurface scattering using a screen-space blur technique.subsurface scattering is just a simplified view of the more general problem of light transport in participating media like clouds, fog, smoke, and interstellar nebula. Many rendering algorithms [PH10] numerically approx-imate light transport in participating media. Monte Carlo methods, such as variants of path tracing [Kaj86] or photonSince subsurface scattering is more pronounced in certain regions (e.g., with light gradient change), we propose an adaptive sampling method based on temporal variance to lower the required number of samples. We propose a one phase adaptive sampling pass that is unbiased, and able to adapt to scene changes due to motion and lighting. ...Nov 7, 2002 · The face was modeled by Steven Stahlberg.

While subsurface scattering effects are crucial for producing realistic images, the computation of light transport using standard path tracing methods for each grain can be prohibitively expensive. Although there have been several methods developed to address this issue, they all assume that bounding spheres of individual grains do not intersect.
