Wow, that's so cool 😲

It'll be group public so anyone can join easily

I'm in 😎

Uh oh... I can't log in to vrc... stuck "Joining..." homeworld 😰

2 hours from now

Also! The core system that the efude calligraphy/painting system uses is very similar compared to the uGraffiti spray system, so with a bit of fiddling, it is possible to draw with them interchangeably - spray on canvas or paint on walls.

I have a world with some random patterns for inspiration. There is also a debug button that lets you take a photo of the drawn image and the alpha channel of the image for exporting vrchat.com/home/world/w...

Personally, I think all non-interpolated drawing systems are lacking in quality. I wonder if I could interpolate occlusion data between frames somehow 🤔 probably not very well...

Unfortunately the lag and jitter between two users is so big that even if someone managed to draw a nice tattoo on their end (unlikely), the other user would see a completely messed up drawing, so I never published that one 😔

It's using an older version of the system so there are some small edge cases where it breaks, but you'll need to search a bit to find them. Btw, that system is also the only version that also works with skinned meshes, I made the avatar tattooing gimmick using that. 😁

The interpolated system can be tried at vrchat.com/home/world/w...

The system currently uses occlusion check for the surface pixels, so it can only draw one point per frame, but it used to have interpolation between the frames, so no matter how fast you moved the can, the spray would still draw a line, rather than breaking up into dots like most other systems

I haven't set up the spray surface on the flower or rocks since I added those just for testing occlusion, and because I don't have the inactive surfce optimization done yet so they'd use up a few extra frames.

The demo world is vrchat.com/home/world/w...

Painting on arbitrary mesh surfaces requires a bit more complex set up, involving blender, etc. so I don't think I'd be able to make a guide that could be followed by anyone to easily set up the full version... 😔 But I guess people wouldn't be interested in that anyways

If I made a simplified version, I think I could sell a booth prefab with a quad or rectangle canvas and a... uhh... fire extinguisher spray that could be just dropped in a world. ...I'd need to whip up a new UI too 😨

The system itself requires some set up for the full functionality, and I got lazy with my upgrades halfway through optimizing it to use 0% performance when not actively spraying a surface. so I'll need to fix that before I can do anything with it again 😅

I wish I knew world makers and graffiti world users so the only world with this system wouldn't be random garage with a van, flower and a few rocks...
