I’m following Blender Guru’s donut tutorial and I’ve reached the part where I should make the glass material. I do exactly what he does (turn up the transmission value to 1 and the roughness down to 0). However I don’t get a realistic result. I then did it with a glass shader, but that didn’t work as well. It looks like this:
Tell me if you have need of additional information. Thanks in advance <3
Are you referring to the fact that the glass looks thick? this is likely due to your objects scale. (if you started with a 1 meter cylinder then the IOR will cause this effect)
If you are referring to noise the sampling can be adjusted or utilize the de-noise option in rendering.

I’m talking about the fact that the liquid inside can’t be seen through the glass and I don’t even know why the grey parts on the upper part of the object happen
Check the objects actual thickness with scale applied. If your cup is thicker than a few mm the physics of light refraction will cause significant bending.

The scaling is already applied
I think I fixed it…
I applied a solidify modifier to fix the already applied one. Now it’s see-through and there is no grey part.
In your top image - it looks like you have inverted normals.

As moony says, inverted normals for sure. Overlays/Face Orientation should make the object appear blue. If it appears red, edit the mesh and invert the normals.
