art3mis Posted December 7, 2019 Share Posted December 7, 2019 (edited) Have a bit of a challenging (for me at least) lighting and rendering challenge. My glass is in the shape of an inverted pyramid that is partially filled with liquid. The glass will be rotating back and forth to move the liquid inside. Would appreciate feedback! I know that my meshed liquid should slightly overlap the glass "walls'. Also I am assuming my fluid meshing is wrong in that the sides should be perfectly smooth, not rough as they appear in the attached. I am using a single HDR dome light. What are some other rendering and lighting tips when doing liquid in glass? Edited December 7, 2019 by art3mis Quote Link to comment Share on other sites More sharing options...
flcc Posted December 7, 2019 Share Posted December 7, 2019 (edited) When rendering liquids in a container, the shape is crucial. If it's not too heavy you should make a boolean to make the corners of your liquid hard (For now ther are too soft), and make liquid overlaping the glass. But you can also do this with shader using nested dielectric. Check this page of the doc about nested dielectric : https://www.sidefx.com/docs/houdini/render/nested.html This work in most of the renderers now. You could also place, behind the pyramide, a luminescent plane visible only by refraction. Edited December 7, 2019 by flcc Quote Link to comment Share on other sites More sharing options...
