Re: Liquid Volumes
Why when you disable Interior Volume from glass the IOR stays the same as in the (Luxcore volume nodes) but refractions are different? Do you have to use Interior Volume with clear glass?
Re: Liquid Volumes
Because the glass volume has a higher priority than the liquid volume, so it "cuts away" some of the liquid.
If you remove the glass, the liquid is no longer "cut away". This creates an invalid volume setup, the IOR on the boundaries is no longer computed correctly etc.
You don't have to use an interior volume in all cases, but in this case it's necessary. Or you have to model the scene differently.
