FS#4 - Integrate Subsurface Scattering with standard lighting code
Subsurface Scattering still uses its own rudimentary code to compute illumination from classic light sources; this must be changed to use the standard light source & shadow handling code, to add support for non-trivial light sources (e.g. spotlights, cylindrical lights, area lights), partially-transparent shadowing objects etc.
As of change #4882, all standard lighting features are now supported. Some issues remain though regarding "insideness".
What is the status of this?
Still some work to do, but nothing to be included in 3.7.0 release proper. After all, subsurface scattering was always meant to enter 3.7.0 as highly experimental.
Area lights are not supported yet; they're still treated like point light sources instead.
I haven't had a closer look at subsurface scattering for a while, and would need a thorough code review to determine what is and what is not still open in this regard; due to the complexity of the interactions with other features, I wouldn't want to close this task based on mere black box testing.
Now tracked on github as issue #141.
