Problem with IBL

#1

I’ve been working on HDMI & IBL recently and have come across the following problem which I hope somebody can assist in resolving.

There are two images I have posted to illustrate the issue at hand. The first image is of a wine glass with fluid inside. You can see how clear it is. The second image is my glass but the fluid is blotchy/distorted. This is what I can’t sort out.

I’m using IBL but nothing I try clears up the distortion and I would like to request help in fixing this problem.
What is causing this?

Any suggestions will be very much appreciated.

Thank you.

There’s no information on your scene set up whatsoever, we need render type, render settings , shaders , lights or even better a scene file.

I would say that it looks like your geo is intersecting.
