Bryce doesnt have true SSS. It has translucency, but it can be rather fiddly to make it look like SSS and even then it will not be easy or should I say fast to render. In the other thread we talked about careful use of things like Ambience. This is one of those occasions where you might be forced to resort to ambience as other workarounds though better looking might be a render time killer. Best of luck.

don’t make green grapes like I did, go with red/purple ones, they’re not as translucent,

If can be done but… as stated it will be time consuming and will need a bit of work.  Along these lines http://www.bryce5.com/details.php?image_id=4463&mode=search

With two objects, one for the outer surface using blurred transmission to break up the ray path through the material and a second object to “mop up” those rays which try to travel through the main body of the object.  All that remains then is rays that dip in and out of the model surface by interacting with the diffuse of the inner object material giving the impression of subsurface scattering.  In the example above, a volumetric material was used to give a very soft transition of density within - this combined with multiple light sources, a transparent outer material and blurred transmissions… resulted in a “longish” render.

@David

I have the same idea with two objects but my test fails. The dragon look´s very good, like ivory.
