Can [TiltBrush Audio Reactivity].prefab be used to link sound and Brush by assigning music? If so, how do I use it?

It's probably fairly easy for some/most of the brushes. Most are fairly simple triangle strips.
What is harder is supporting all our brushes with a high degree of fidelity. It's one of those tasks where you'll spend 80% of your time on the last 20%

this spreadsheet is a bit of a mess but there's a ton of useful info in there: https://docs.google.com/spreadsheets/d/12fHPnMNhpGGdR1mzFeCjXbg1Nv1PO1LZGcHwgp3S1Og/edit

There's also a difference between the shaders in the main repo and the shaders in the Unity SDK/Toolkit. On export we remap some of the extra UV info.
I think it mainly affects the particle brushes.

We only have URP brushes in an unreleased toolkit branch - the main repo is all BiRP.

Not sure what you mean? Just use the URP ones from the toolkit.
You can grab them from here: https://github.com/icosa-foundation/open-brush-unity-tools

(that's new and has less cruft in if you just need the shaders and materials)
The main thing to figure out for each brush is how the uv mapping is interpreted. Probably best to just compare with an export from OB itself. Use this sketch.

Would this be an issue if the OB shaders were converted to URP rather than using the ones from the toolkit?Why would that be any different from the the URP ones that are already converted?
