I had this Idea in mind for a long time. It all started out with a joke about eating in an S-Bahn (public transport trains in Germany). I basically want to create a scene where one wagon of an S-Bahn is replaced with a giant hot dog. I created this abomination in paint (with a mouse) to visualize what I’m going for.
I also created a reference board for the S-Bahn Modeling because I couldn’t find a fitting 3D Model I could use or wanted to pay for (made in PureRef):
Then I hopped in Blender and started modeling the S-Bahn:
I used the CCO Human Scale Reference Model from this video: Interior Tutorial by Blender Guru
