UV unwrapping the exterior of a hollow cylinder I'm pretty new to blender, and only have some idea of what I'm doing when it comes to UV unwrapping. Basically I'm trying to add a texture to the exterior of a hollow cylinder, but every time I unwrap it it also unwraps the interior which is not what I want.

Could the solidify modifier I put on the cylinder be causing this issue?
Apply your Solidify modifier so that the inner side will is different, now you are able to give it another texture.
