    The following error appears when raycasting towards certain meshes in built player. So far, I haven't been able to reproduce this in a fresh project (even by using the affected meshes and their .meta files), so I cannot submit a bug report as of yet.

    Code (CSharp):
    1. [Physics.PhysX] TriangleMesh::loadFromDesc: desc.isValid() failed!
    2. UnityEngine.PhysicsScene:Internal_Raycast_Injected(PhysicsScene&, Ray&, Single, RaycastHit&, Int32, QueryTriggerInteraction)
    3. UnityEngine.PhysicsScene:Internal_Raycast(PhysicsScene, Ray, Single, RaycastHit&, Int32, QueryTriggerInteraction)
    4. UnityEngine.PhysicsScene:Raycast(Vector3, Vector3, RaycastHit&, Single, Int32, QueryTriggerInteraction) (at /home/builduser/buildslave/unity/build/Modules/Physics/ScriptBindings/Dynamics.bindings.cs:700)
    5. UnityEngine.Physics:Raycast(Vector3, Vector3, RaycastHit&, Single) (at /home/builduser/buildslave/unity/build/Modules/Physics/ScriptBindings/Dynamics.bindings.cs:1041)
    6. Player:OnAnimatorIK() (at /home/user/Path/To/Project/Assets/Code/Player/Player.cs:417)
    I don't know what's causing it, but this is the information that I have:
    • The error points to a line that does a simple raycast. If I comment the line out, the error will point to the next Physics.Raycast() or Physics.SphereCast() operation.
    • Disabling "Graphics Jobs" in player settings used to resolve this error in previous versions of Unity (based on my git log, 2019.2.0b4 was fine, and I think the beta versions of 2019.3 (before f1) worked too)
    Maybe someone with access to the Unity source code can share a few ideas?

    Edit: I forgot to mention, I started seeing this error after I swapped out my Nvidia graphics card for an AMD one (Radeon RX 580)

    Edit 2: Looks like the issue only occurs when static batching is turned on

    Edit 3: The error resurfaced when I continued working on my level, even with static batching turned off.

    Edit 4: I decided to remove certain directories inside "Library" including "metadata" and a few others to see if this would fix an unrelated issue, which it did (my project would take over 5 minutes to open, but now it opens reasonably quickly). I've been experimenting a little I think it fixed this error as well, as I haven't seen it since. I'll update the post if I start seeing it again.

    Same issue here.
    Everything is working fine but still getting this error:
    [Physics.PhysX] TriangleMesh::loadFromDesc: desc.isValid() failed!
    Any advance there? I use Nvidia card too.
