Quote - Sub- Surface Scattering. Certain materials (skin, orange juice, wax) do not reflect all light on their surface. Light enters the object and is reflected inside the object. IMHO it is possible to fake SSS without Ray Tracing.

Well, it can be done without ray tracing, it's only an illumination model.

The difference between ray tracing and not is that in the second the rays of propagates in straight light and ends when hit the last not transparent object.
With ray tracing the rays can be reflected and then in another direction where can be reflected again and also the rays can bend due refraction.
But the method without ray tracing can be very fast and done in real time.
I don't know which renderers beside games that use this method.
Poser 4 I don't know what it is, it looks as some limited ray tracer because the scene appears slowly line by line and not in an instant with all whole scene rendered.

Stupidity also evolves!
