You have just been swallowed by Venezuelan beauty Marilisa Quintero (her face is shown in inset, my invented character, no intentional likeness to any living person). You can see the last rays of light filtering through her teeth as she closes her mouth and swallows again forcing you into her throat. Everything is so wet and slippery, you have no way to stop the inevitable. Say goodbye.
I would like to thank the phenomenal render artist Flagg3D flagg3d.deviantart.com/
for answering my question of how to render inside a 3D character's mouth. Worked like a charm, thanks again!
The mouth is G3F with some D-former applied to open up the throat allowing the camera down there. The tongue is Lickit2 with customer diffuse and displacement maps.
