I have a mesh render prefab that I can attach to characters to visualize their vision. Unfortunately the mesh render does not display the mesh on the camera when the origin is off camera. So for instance if the camera is following the main character they wont see the vision cone until the charter that’s projecting the vision cone moves into view, possibly quite a bit after they should be able to see the cone. In the attached screen shot you can see in the scene view the white blob is the mesh, and in the game view its not being displayed.
PS: the character in the case is at the bottom right of the white blob, I was messing with setting, in particular the material before I realized the issue was the mesh.
