Jagged Lines in Mesh

[MFRS]

So in the Editor my mesh displays like this:

How can I get rid of those annoying jagged lines?

I have both uvw channels which I double checked, I have increased the chamfer to a high poly count to see if it was because it was low poly and I still get these lines. Any suggestions?

not sure what im seeing in the image.is it in game or static mesh viewer?

could be smooting groups.

It's in PIE, tried smoothing groups as well already :/
