Garment explodes on Android, but not in editor (also some ParticleShader errors) - CptnFabulous - 28-10-2024

I upgraded to Obi Cloth 7.0.3, from 6.5.4. I'm using Unity 2021.3.3f1.

After fixing some compile errors (and deleting and reinstalling the entire package to prevent compile errors from improper importation), the fabric simulation is far more performant. But while the fabric simulates the same as before in the editor, when I built and tested on Android, the created garments would ‘explode’ and burst away from the mannequin at a high velocity.

I know this kind of glitch is common with fabric simulations, but I’m not sure how the differing platforms could cause this error, so I don’t want to make changes to the many existing settings.

It’s possible that this is an ‘editor vs. build’ thing, rather than a ‘Windows vs. mobile’ thing. I tried making a Windows build to test, and it initially failed due to some shader errors in Shader Graphs/ParticleShader, but after deleting the whole package and reimporting it, it built successfully to Windows (where the fabric didn't glitch out). However, this now meant that the compiling failed when trying to build to Android, with the same ParticleShader errors (plus one more). I'll list them here:

This third one is the one that only appeared when trying to build to Android.

Code:

One additional error: when I stop play mode while the cloth simulation is active, the editor crashes. To work around this, I have to instead pause, wait a few minutes, then end play mode.

What issues could be causing all of this? I've done a heap of testing, but I wanted to post my experiences here in case there's a really obvious thing I've missed.

EDIT: I also created a blank project (in the same editor version) and installed the same version of Obi Cloth, and it built to both Windows and Android fine.
