Amesley,
The key to good looking glass is having good lighting with highlights, reflection and correct shadows.
Unfortunately in regards to lighting an interior scene the Blender Guru’s tutorial is not a good one. Having only a far away area light gives diffuse type lighting and shadows.
I modified the Blender Guru’s tutorial with my workflow for lighting this type of interior scene.
- Remove the far away area light.
- Added sun light and an area light on the window.
- Added reflection cube map tor the room.
- Added irradiance volume to the room.
- Use my all standard shadow and light settings. (Look at my other post for these.
- Adjusted correctly all the other scene settings.
These changes will give this scene a proper sun lit look. Their is highlights and reflection on the glasses. Notice the realistic shadows specially chair legs shadows on the floor and others.
