Hello everyone, I hope you are having a good day. I am working on a scene and hope someone can help me understand what is causing a rendering problem. I am trying to better understand how rendering works in houdini. The fluid is a brown color to simulate coke. Everything was going good until I added the ice cubes. Since I did that the fluid turns white when it goes in the cup, close to the cubes. I hope someone can help me figure this out. Thank you and have a nice day

That is the nature of reflection and refraction. The colors from the environment are calculated through the surface. If you don't want to see that you can turn it off at the material level. Dive into the basicliquid material and locate the Settings tab. Set the value for Inside IOR to 1.0.

The IOR or Index of Refraction is a mathematical light bending algorithm used to simulate the light passing through a surface. You can emulate various materials from water to diamonds by simply setting the appropriate IOR.
