    I'm getting these errors when trying to bake either MeshCollider or a physics shape that has its Shape Type set to Mesh:

    Does anybody know what might cause these errors?
    The physics package version is 1.0.14.
    All the meshes are marked as static.

    I get this spam constantly when using the physics sample package. I'm not sure what is triggering it. I thought it might be LODGroups with only LOD0 containing a collider, but I'm actually pretty sure it isn't that.

    Good to know. I am at a loss as to where this is coming from. On the bright side, besides the spam this produces everything seems to work fine.
