I’m trying to make a beer glass with beer in it. I modeled the glass and beer using spin. Gave the glass a clear glass material and the beer colored glass material. Using Yafray with HDRI for lighting and a light added to brighten the scene.
Here is the problem. The glass is fine if empty, but with the beer in it there are very unnatural looking reflectons of the floor. I’ve tried many combinations of IOR, reflection, and fensel but it still looks like this.
