Sub Surface Scattering on Filter Forge ??

As far as I know this is used on 3D software but HOW would you use this in a 2D software and how would be implemented inside FF ?

Please, if you explain it better what is your idea it could help much to FF developers and others to understand what you have in mind as suggestion.

Oh noes, forum ate my post.
I have a bit left and will rewrite some more roughly:

Think highly wrinkled skin, mountains of wax, grapes, porcelain with valleys and ridges.
It kind of could me mimicked globally via the lighting, but since there is no way to influence ambient light with a map and there is no self illumination map (that I'm aware of ) it couldn't be done locally. You could construct your own more ore less basic lighting with Derivative or something like that, but that's a bit cumbersome.
Or use the height map with a high pass to identify ridges, combine that with a raised ambient level and add a dynamic light for specular only. Perhaps an additional, dimmer one to add to the fake diffuse. But I wouldn't call that practical.

We don't know what's behind our surface but could provide that information.
We have a 3dimensional surface* and can calculate the "depth" in x and y.

*The heightmap is probably converted to elevation/normal information for most operations, but the information is there. AO seems to make use of it, too.


But like said, it's more like a gimmick or "nice to have".
