Hello,
I'm just asking here for a quick clarification on what is considered the "correct" way to interface liquids and glass. In this case we have (rough) droplets on a bottle surface that render dreadfully if the normals of the liquid in the bottle are pointing outwards. If I set the normals of the liquid inwards, the droplets on the bottle render great.
"So what's the problem ? ", you might ask.
1) Fog color on fluids return an inverse color ( Green plastic Pet Bottles suddenly look like they're filled with a red liquid) -notably, refraction color green returns green.
2) something just feels wrong with this approach.
Nothing wrong with asking here, I assume. (diagram attached to illustrate)
note, the image illustration involves a light source behind the bottle as per studio request.
