Making Translucent Skin

Skill Level: Regular / Views: 3858 / System Requirements: Poser 7 or higher

This is a simple yet powerful material that gives good realism and an extra trick for the ears.You'll need some Poser skills, but I'll try and explain on the way...English is not my best, so i hope you'll accept a few errors :)

Background



When a lightbeam hits your skin it basicly does two things. Some of it reflect and some of it scatter beneath the surface. Have you ever tried to hold your hand in front of a light? It's glowing red, because some of the light passes through it. Ears are pretty thin compared to a hand, and have a lot of blood flowing through them, therefore you'll be able to see the effect if you take a light and put it behind someones ear. It becomes tranlucent, with a red glow, especially at the thinnest parts. To spare your surroundings for the light test, look at the ear that I've rendered. Do you see the light passing through?

There are many ways to simulate that. One of the buzz words in 3D is called Sub Surface Scattering. It does exactly that. Scatters light under the surface. In poser it's called Fastscatter, and it's not true Sub Surface Scattering, but it does the job, and as the name implies it's fast :)

Saludos. Este tutorial es excelente. Contestó mi pregunta sobre como lograr el efecto de la luz pasando a través del cartílago de la oreja. Ahora mis "renders" serán aún más reales. Muchas gracias. Greetings. This tutorial is awesome. It showed me how to have Sub Surface Scattering at the ears. Now my renders will be more realistic. Thank you so much.

Hello. Great tutorial. I am trying to follow along but am stuck at on page 5, as when you're supposed to add the fatscatter and edgeblend nodes, those are to be the only two nodes. The default V4 comes with nodes already added and a skin texture. You stated you were using a "Bonnie" morph but no skin texture. In any case, the diagram on page 5 shows there are no textures, just those two nodes you instructed us to add.
