How to get rid of jagged edges on gigantic mesh

That is expected to happen due to precision issues, including z-buffer precision. Try moving near clip plane further.

The problem only happens on this mesh, most likely because it is enormous. The problem persists if I turn off shadows on the mesh, and with whatever type of light I try to use. I don’t think this is a typical shadows/lightmaps problem. This happens because of the size of the mesh. The mesh is currently a static mesh but I intend to change it to a skeletal mesh once I figure out this problem.

Placing it to 1 or 2 was enough to solve the issue. Thanks a lot.
