I created a lens mesh and applied a material to it. When I look through the lens mesh, I can see the world, but I also see the interior of the optics mesh itself. How can I mask or hide the weapon mesh and the optics mesh inside the lens material, so that only the world is visible through it?
So, could you describe in a different way, your desired outcome?
That geometry poking in through the interior seems like an issue with the mesh construction, although it almost looks like a nanite proxy mesh?
