Why do I get temporary seams on my characters?

So, as the image shows, I’m getting some weird seams on my characters in my packaged game. Thing thing is that these seams go away after my camera gets closer to the character. I’m guessing the issue is something obvious but I really have no idea what to look for. If anyone could let me know what to change to make these seams go away at the start, it would be much appreciated.

Thank you

My guess is that it’s related to mipmaps. Try this to see if it helps isolate the problem:

Find the textures used by your character’s material. Open the texture editor for each of them (albedo/diffuse, normal, etc) and disable mipmaps. Do you still see the problem?
