Each side keeps on disappearing. It’s there, but when I move on one side, the other half disappears. I’ve tried to copy and paste them to the other side but that didn’t work either. Does anyone know how to fix? And yes, I forgot to anchor the meshes haha.
Mesh faces can only face in one direction, and you’ll have to solidify it so that you can’t see through either side. If you’re using Blender, you can apply the Solidify modifer to the mesh and change the thickness to your liking (very thin in this case).
