The Persistence of Vision Raytracer (POV-Ray).

This is the legacy Bug Tracking System for the POV-Ray project. Bugs listed here are being migrated to our github issue tracker. Please refer to that for new reports or updates to existing ones on this system.

This looks done to me. Cut and paste from the current 3.7.1 documentation:

Subsurface and Radiosity

To specify whether radiosity sampling should honor subsurface light transport, you should place the following in the global settings radiosity block:

global_settings {
  radiosity { subsurface BOOL }
  }

If this setting is off, the default, radiosity based diffuse illumination is computed as if the surrounding objects had subsurface light transport turned off. Setting this to on may improve realism especially in the presence of materials with high translucency, but at some cost in rendering time.

To specify whether subsurface light transport effects should be applied to incoming radiosity based diffuse illumination, you should place the following in the global settings subsurface block:

global_settings {
  subsurface { radiosity BOOL }
  }

If this setting is off, the default, subsurface light transport effects will only be applied to direct illumination from classic light sources. Setting this feature to on will improve realism especially for materials with high translucency, but at a significant cost in rendering time.
