Hello,
I was a little bit bored, so I decided to create a Nuka Cola bottle from Fallout 4. 
But the problem is that the glass is behaving very weird. I’ve watched thousands of tutorials about making bottles and glasses, but the only step they did was setting the material to Glass BSDF.
Here is what the bottle looks like:
(The black stuff is the soda, but even without it, the glass is reflecting itself)
I don’t know what’s the problem. Maybe a hardware based one? 
***I’m using Blender 2.78b and I use the Nvidia GeForce GTX760 to render my images.
