For the scene I'm running a simulation to have a liquid pour into the glass.

As of now there is two issues 1. The material shows a giant hole in my cup 2. The material isn't quite rendering like glass.

I looked at some other glass tutorials and they didn't require much on the lighting side at all.

I put an environment light with an Intensity at 0.7 but it hasn't change the transparency of the glass or the hole that is rendering.

Hi, the main issue is that your normals are reversed. You can use a reverse sop to fix it and work on the material from there.
