I have a plane with a MeshCollider, and it has weird problems with raycasting. It seems that when I cast a ray from the top of the plane, it works fine. The raycast can detect that it hits the plane. But when I cast a ray from the bottom of the plane, it doesn't detect that it hits the plane. I drew a line and the ray should hit the plane.
When I change the MeshCollider to BoxCollider, the rays work correctly.
Is there any reason for this problem? How can can I shoot a ray from beneath the plane with a MeshCollider?

Hello, can you see the mesh from both sides? Yes Colliders are mostly made to work just in one direction, there may be a workaround for double sided planes, although in games they normally have 2 planes
Does it mean it will only work on the side with the normal vector pointing forward?
