I'm pretty new to 3D modeling and Blender and I'm trying to make a modular tileset which includes walls. I'm stumped at exactly how to shape the inside corner where two of my curved walls meet. The current way I've done it obviously causes artifacts and doesn't look quite right. I'm having a hard time wrapping my mind around the geometry in this area so if someone could point me in the right direction it would be greatly appreciated. Even if I have to redo the whole thing.
