When someone would make holes in water surface using boolean then also (fix me here if i'm wrong)
but we need to extrude from hole edges to bottom and make water mesh solid, or not?

But how does red light ray know it's in water or has been in meanwhile?
neo2068 wrote:That's right. I only addressed the issue of the dotted red water surface inside the green object. That has to be removed. The other problem is to correctly assign the interfaces. You have to split the green object, i.e. the glass box, into 2 materials. One for the glass/air interface and another for the glass/water interface.
neo2068 wrote:Your sketch implies that there are two surfaces on the water and glass border. Actually, there only has to be only one surface, the glass/water interface. There has been other threads that discussed this matter:

Correct is that way:
