Lighting and uvs problem in ue4

Hi guys
so I’m running to a little problem in ue4 with my model , I’m planning to get close up shots of my model so i need to fix this . basically as you can see in the picture , in ue4 the lighting makes the parts where I’ve cut the uvs very obvious , is there any way to fix this within the engine or do i need to redo the uvs for that part

Can you pucture UVs that are used?

the blue arrows shows the metal part in the picture and the red arrow shows the paint part , the cuts are not as visible in the paint parts
