I'm following this tutorial and I have applied a material to the body mesh and when I apply the material to the faces to the side of the mesh, I can see the top/bottom material is showing on the top and bottom parts of the side faces.
This is the rendered view:
and this is the wireframe showing the selected faces which the side material is applied to: https://i.stack.imgur.com/mD2XI.png
I'm not sure why this is happening, can anyone advise? Thanks
