Regression

Yes

Transform.position() values becomes to NaN when one GameObject rotates while colliding the edge of another GameObject

Physics

-

To reproduce:
1. Open repro project
2. Play scene
3. Using arrow keys (or w,a,s,d) move cube to the corner of ground

Expected: when cube('player' game object) collides with 'ground' corner, player's position values should not be set to NaN

    The methods presented in the comments here did not help me. Here is my option that helped and does not affect the FPS: https://github.com/pazenkin/RigidbodyFixer

    The error is relevant in 2019.4.6. Is there any solution?

    I had the same problem with Unity 2017.4.40f1.
    My solution:

    Mesh Collider Convex off.

    I have a platform that rises and falls. The player goes on the platform and the first person controller everything on NaN.

    Mesch Colider of the platform (with sloping and protruding elements) had Convex on.

    Many thanks to the answers here!

    Still happens in Unity 2018.2.19f1 and above, super frustrating

    In 2017.3.0f3 this error was killing the game both in the editor and a build, fixed it by following the suggestion of changing physics contacts generation to legacy.

    I was having this problem happening all the time (in 2017.4.15, editor and builds), but as was suggested in an earlier comment, switching contacts generation from PCM to legacy in the physics manager does seem to avoid the issue.

    This might only be loosely related and pretty specific, but, if you're using MeshColliders, check the collider mesh for vertex doubles (vertices at almost the same position) and remove them.

    I had the AABB issues and removing doubles in the Collission Mesh fixed them.
