How can I properly add a subdivision surface to the side of a model? Eevee Blender 2.82a I am working on a Star Destroyer model. I am at the point where I want to add textures. I want to add a subdivision surface modifier to the side of the ship only. I went into edit mode, selected the side (it has a mirror modifier), unwrapped it, added a texture and compiled some nodes together. I added the subdivision modifier. Firstly, this modifier is affecting the entire ship and not only the selected side. Secondly, I am not seeing the modifier's effect on the sides. I am including an image of my result and one of what I want to achieve. I tried with the discombobulator instead but it isn't working so I am assuming that my side isn't made up of quads. Any assistance would be greatly appreciated. Thanks
you could try going into edit mode, selecting the side of the ship, and in the right-click menu select subdivide
