    Resolution Note:

    Particles using Mesh Rendering require the Mesh to be marked as Readable so the system can get access to the raw vertex data. If the mesh is in the same bundle as the particle system, the native build pipeline can mark the mesh as readable appropriately. Otherwise the mesh has to be manually marked as readable if it is stored in another bundle. This is a limitation that is unfixable in the native build pipeline and was solved in it's replacement, the scriptable build pipeline and this case has been verified to be fixed by using this. The upgrade guide for SBP can be found here: https://docs.unity3d.com/Packages/com.unity.scriptablebuildpipeline@1.7/manual/UpgradeGuide.html
