Lines of Material coming off actor.

When I was adding to my walls and floors this started happening.

But only when I look from the side from the front it looks like.

Anyone have any idea of whats happening?

Are you using a translucent material by any chance?

is your material set to “Two Sided”?

Theres a glass wall in the middle of it could that cause the effect?

It not set to two sided.

That’s it then. Open up the glass material and unplug refraction.
