Yes, all the implications are as you guys say.  Ice-boy, if they give me a way to spawn more rays, specific ones that I ask for in the shader node, then yes I could do real SSS, and you could use it in things like candles and grapes and little bugs, and of course back-lit ears on a human.

For a given item to rely on an add-on package of nodes (which is just content, after all) is no different than being unable to use a certain character package unless you already own the V4 Morphs++. Basically, just as characters are just dial spins (parameters) on an extra set of morph that everybody buys, so too would these new materials be dial spins (parameters) on an extra set of nodes that everybody buys. From me. heheheh

By analogy, you would need VSS Nodes++ and then all sorts of new better easier-to-make props and clothing and such would be automatic.

For example, suppose I made the Matmatic Loom into a node. You'd have instant totally realistic cloth for any clothing item.

But we are all just ... theorizing here. That's my official story anyway.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
