Skin Rendering Lines

Hello,

I have a problem in my game where the skin of my character will show some sort of white lines atop of it. This bug seem to be recent as I didn’t have it before and I rarely touch the texture of my game as Im more of a programmer than of an artist.

For the game, I am using Mega-Fiers (On the asset store) to render the character with the SkinnedMeshRender.

Let me show you some screen shot of the said lines. So you can help me find a solution.

It seem to be like cutting in line over the body. It goes around the body, between the shapes and draw line like it is splitting the character in 2 entities. Is it some sort of bleeding? Im quite unsure. I have checked the texture themselves and it seem to be no problem.

For further question, the project was in Unity 5 at first and then moved to Unity 2018 for a while. But when we moved to 2018 we didn’t have that problem either, so it seem to be recent maybe of an update?

If someone can help me, would be appreciated. Thanks you for your time.

It’s mipmap generation artifact, you should bleed UV islands border pixels to the empty space(solidify from Flaming pear do the job)
