after a few hours of hairpulling trial end error I ended up more confused than before. I am not extremely familiar with all that blender has to offer, however I decided to take the task of modelling something for my game. I am trying to make a spaceship corridor, but whenever I try to paint on the walls that are extruded from the floor plane, Blender paints weird angles and artifacts, and I have no clue what is wrong. If there is anyone who knows what causes this, help would be greatly appreciated. I even considered separately painting every part and then combining the textures, but I refuse to think that there is not an option I am missing that has to do with my issue.
