Quote - Here is a closeup:

"Sun" + IBL fill vs single light.

No IDL as the scene is empty. GC + SSS enabled.

Skin shader is Bagginsbills latest via EZSkin with some light tweaks.

Is there a ground? Then it isn't empty and you should enable IDL.

Reflected lighting from the ground is a big deal.

Also, under the chin is lit by the chest. Under the ear is lit by the neck.

Always enable IDL.

Think about this.

Imagine a performer on a broadway stage lit by just a single spotlight, with a wood floor, a black curtain behind, and with the auditorium parts (walls, people, chairs) otherwise black and/or far enough away that the bounced light has decreased to unimportance.

When you simulate this, which of the following would you think is more accurate:

No IDL

IDL bouncing light from body part to body part, and from floor (Poser ground) to figure.

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)
