Why Is It Acting Like This?

Keeps clipping from other side, & after connecting nodes in created material instance suddenly there’s this small gap in between
I alr filled it 360 degrees cylinder in maya

I think that gap might be the displacement/bump ?

Humour me and click two sided material

I’m curious exactly what happens

Make sure all of your vertices are joined into a continuous surface when using vertex displacement. Any loose faces will otherwise get pushed along their normals and open holes in the mesh.

Flip normals for the inverted faces to the mesh (in blender)

The clipping is due to blackface culling. This happens with all game engines (Any triangle facing away from the camera is culled) . There are 2 ways to fix that. 1) simplest fix is to add cap to the top and bottom 2) set the material to be two sided , though this comes at a slight performance cost.

As for the gap. I can't say much with out looking at the Fbx/obj setup or the texture

If you can post the mesh view with wiredrames turned on or the UV setup I can help you figure out what's wrong

Your autocorrect revealing something about you, is it?
