cnballpit-vrc

Finally released! See it here: https://vrchat.com/home/world/wrld_e54f6579-ceb1-4805-a967-e869e586b8d2

Right now, I haven't quite got the unity packages able to be exported, but you can clone and use the prefabs.

If you use this ballpit, I would appreciate a call out, but all code that is mine is under the MIT/x11 license.

TODO

• Figure out why shadow edge length too short.
• Add shadows to the balls.
• Make ball pit use SDF for boundary.

Special Thanks

• D4rkPl4y3r for the idea, and several pointers! Also, the binning principle.

• Everyone on the VRC Shader Discord for the 50+ questions I had to ask to write this.

VR Computer RTX 2070, Ryzen 3900X; Index at 144 Hz, 122%. Numbers are minimum times, peak up to about .3ms higher... So, signal in data is pretty good, probably around +/- .2ms.

Conclusion when doing camera shimshammery: Put cameras and objects on PickupNoEnvironment. Cull for all objects not on PickupNoEnvironment Your layers don't matter.

Numbers with quick menu closed / open / With AudioLink and basic video player Same layers, PickupNoEnvironment: 7.6ms / 9.3ms Camera on default, looking at PickupNoEnvironment: 8.2ms / 10.0ms Camera on UiMenu, looking at UiMenu: 8.1ms / 10.1ms Camera on default, looking at UiMenu: 8.1 / 10.1 ms (repeat) Camera on PickupNoEnvironment, looking at PickupNoEnvironment: 7.6ms / 9.4ms Control: Everything off: 7ms / 7ms (framecap) (1.6ms / 2.5ms) Control: Only AudioLink: 7ms / 7ms (framecap) (1.8ms / 2.7ms) (repeat) Camera on PickupNoEnvironment, looking at PickupNoEnvironment: 8.1ms / 9.4ms Camera on UiMenu, looking at UiMenu: 7.6ms / 9.3ms

Control Update Test

• Running uncapped, baseline 5.505ms / 4.17MB

• .5ms Udon time / 11.250ms / 4.19MB
• Removing VRCObjectSync
• .35ms Udon time / 6.3ms / 4.19MB
• Deltas:
• With VRCObjectSync: .15ms UDON Time / 5.75ms Frame Time
• Without VRCObjectSync: 0ms UDON Time / 0.8ms Frame Time
• Switching my object to manual: 0ms UDON Time / 0.6ms Frame Time
• Adding an Update() method with i=0: 1.5ms UDON Time / 2.2ms Frame Time
• Using a brokered update function : .3ms UDON Time / 0.9ms Frame Time
• BetterObjectSync -> Going back to original scene.
• 5.261ms.
• Took exact thing from TEST to Upload version and visit with --fps=0 and in RenderDoc, it was 4.757ms
