VR ↑ and 360° ↓ sketches
Happy puzzles. VR and 360° are two different processes, but I put them together because they deal with similar senses. Working with either medium is not as intuitive and tangible as I've hoped. Goro Fujita has made VR painting seem so easy, when in truth he did a tremendous amount of practices. Painting with Quill, to me, is like squeezing toothpaste that freezes in the air.
Also, I wrote some notes on 360° sketching and they can be found under writings (near the bottom).
