What you did

I cast a ray from camera using MeshRayCast to the meshes I loaded and visualize the first intersection using gizmos.

A small code base for reproduction

What went wrong

• what were you expecting?
  All intersections should be just on the surfaces of meshes
• what actually happened?
  Some intersections are inside the meshes or just in the air.

correct

inside

in the air

Additional information

MeshRayCast works on the suzanne model but not on the zombie model.

That's surprising. Thanks for the reproduction. I suspect there's something weird about the model that we're not handling properly.

It looks like the cast_ray function only performs ray cast on meshes without skinning
