Here is the tutorial in a nutshell. These are the steps reduced to simple bullet points:
Modelling the Cup:
Creating the cup handles
Creating the candle
Creating the Vase
Here are a few renders of the final scene. Once the models and assets were completed, I created low-poly versions of all the pieces and used Substance Painter to bake the maps and create the textures. The screenshots are from Marmoset Toolbag 3.
