Houdini: Render glass/water, nested dielectrics

Render glass/water, nested dielectrics


        (intersection glass with water, for bottle)

        make stuff intersect

        enable nested dielectrics in render node
            mantra node -> rendering tab -> shading -> 
                check enable Absorbtion and Nested Dielectrics

        set priority parameter in texture:
            principled shader -> surface tab -> transparency
                enter surface priority
