Recently I saw a process video of putting together a panoramic 3D Chemical laboratory. It was the backdrop of a children’s game about the table of elements called Tablecraft. The cool thing about this video is that it starts with a rough 360 concept sketch and fades into a fully modelled 3D environment. It is a fine example of a potential dev pipeline for VR world building.
The game designer said his artist worked magic in Blender and make the 360 panoramic sketch quickly. It screamed the new Grease Pencil tool in Blender 2.8 to me. I then found a recent tutorial by Jama Jurabaev on how to create a 360 panorama view using the Grease Pencil tool in Blender 2.8.
