Definitive method for modelling Glass + Liquid in Octane?
Posted: Fri Oct 21, 2016 2:11 pm
Can the developers give the definitive answer for this as it's different for different renderers and I haven't been able to find the answer through searching the forum.
Eg in Vray you would model the glass as a normal closed volume, model the liquid as a separate volume but have the liquid slightly larger than the inner surface of the glass so they intersect. All normals facing outward from their respective volumes.
I've read about other renderers requiring the liquid to be completely enclosed within the glass volume.
Which is the correct method for Octane and will this method be absolutely physically correct? I'm not normally that bothered about physical correctness but in the instance where the render has to perfectly match a client's product it is.
