Cloth physics not rendering on Android

I'm experiencing what I believe is a bug in the URP: objects with cloth physics work perfectly fine in the editor but not on Android. I think it could be that the skinned mesh renderer gets culled because the entity doesn't have any bones or morph maps, ignoring the fact that it definitely has a cloth component attached.

To confirm my suspicions I have tried to add a morph map to my mesh, at which point it did start rendering, but no longer received physics. I also tried having the mesh with a skinned renderer without any cloth physics, and it stopped rendering on Android (confirming that the cloth component has nothing to do with it).

Does anyone know if I'm missing something, or if there are workarounds?
Many thanks

 

Which Unity version are you using? I'm facing the same issue with the Cloth component on Android, using Unity 2019.1.6f1.

 

I'm using 2019.3.b7 with URP 7.1.2

 

It seems that this is the only way to support Cloth on mobile devices in Unity (supports Unity 2018.x only):

BTW I have tried other OBI assets like Obi Rope and works perfectly fine on Android and iPhone devices.

 

Hello! I got this error (cloth object not appearing on mobile iOS/Android) and the Xcode log said:
"CollisionMeshData couldn't be created because the mesh has been marked as non-accessible."

So the fix was to enable read/write in model Import Settings (so go to the asset for the mesh/3d model itself, and click "read/write enabled" to turn it on in inspector). That was it!

 

Thank you @BlinksTale.

 

Thank you it work !

 

To clarify: Read/Write access on the meshes modell that require cloth physics always had to be enabled. I think this is no new behaviour.

 

It work perfectly even without read/write enabled but sometimes it depend a lot from mesh itself. For example if you haven't applied a modifier on blender to your mesh like (mirror or bevel) after building it for android it just disappears, after i applied and rebuild it again it appeared without problems. So i did some tests and result is that modifier can cause that as well.

 

Thanks !!!
