This is not a personnal project, but a corporate one, by Axeon 360 .
We’ve first made a version of this project by the end of 2016, using StandardMaterial workflow as… PBR didn’t existing yet on BJS You can take a look at how we take deep into BJS 2.5 at this time here : Virtual Staging - Standard workflow.
The purpose of this app is to allow customers to set up their future apartment before buying it (floor materials, walls painting, etc).
Then, middle of 2018 (if I remember well) we decided to convert this demo into PBR shading to enhance visual quality. The app is still runnning on BJS v3.3.0-beta, no fear :

PS: in the same way as Hyperion project, if you’re snooping around the code, you’ll may be introduced into our soon-open-sourced workflow helper tool
