Some months ago I get Oculus Quest helmet and that' something truly awesome =)
I interested in 3D, but it always seems too complex and hard to study, also modelling is very slow process, sometimes after trying I decided that it's easier to pant in 2D what I want, however, it's very enthralling process. But Gravity Sketch is very nice to me, it's almost intuitive, and Marmoset is cool for show this quick thing in motion! So excited to try this combo =) I needed some practice to reduce camera jumping, but I hope you like it.
Also what is the greatest stuff about VR sketching - it evolves feeling of volume and space. I hope one day I'll get a chance to take participation in making a VR project.
