I'd like to share my process on a project that I was commissioned and that was to create a 3D model of a Tiger Beer bottle to be uploaded in a website and used in a similar way like in sketchfab that the viewer can zoom in and rotate it. Everything was all done in C4D and Octane.
These are some of my early test renders.
Sketchfab test of the beer bottle 
After delivering the 3D model I wanted to push it even further because I was not satisfied with how it looked. I decided to create hero shots of it using Octane in C4D. Here are the multipasses I used for the shots. 
AO Pass from octane 
Post Effects Pass 
Reflection Indirect Pass
Refraction Pass 
Z Depth Pass
These are the images I came up with.
