Quote - I think it does not. i tryed now some renders and the bump is the same. 

Aaahh. Just tested with PR3 and you're right, it doesn't smooth it. Months ago I had a shader that did, but I changed how I fake the SSS and now it doesn't. Sigh.

It's very difficult to exactly fake the SSS. My shader cannot produce that look of translucence on a small scale. All it does is get the general large-scale color closer to that which would be produced by SSS. But to get the real effect, we need the real physics to be modeled.

It's like I'm trying to simulate the physics of a bouncing rubber ball, only my ball model doesn't flex and compress. So such a simulation would behave directionally correct in that the final trajectory of the ball would be about the same, but during the actual bounce event it behaves like a billiard ball instead of a basketball.

Similarly, the overall color of my shader is directionally correct in that the large-scale illumination looks similar to SSS, but the details are different.
