There are weird shadows on my model and I have no idea why. enter image description here

I thought it was because there was no lighting inside the model, but when I added in lights the problem still continued to persist.

  • $\begingroup$ Could you explicitate which are the weird shadows? $\endgroup$ – Carlo May 13 '18 at 22:07

That's a smoothing artifact, caused by the pronounced angle on the border of the glass. You can check Autosmooth in Mesh/Normals to get rid of it.

Smooth shading with and without Autosmooth

Note that Autosmmoth is a render trick (as well as Smooth shading), it doesn't actually modify the mesh. So for some cases, it won't work well. As an alternative, you can use a Edgesplit modifier instead : it will physically cut the edges, instead of simply adjusting the normals.
