Working in Blender I had to think about the face normals and make sure that they were all facing the right way so that when it came to texture painting, I would paint on the right sides. You can see the direction of the normals by looking at the blue lines protruding from the faces.
I also worked on creating a ‘lip’ on the left-hand side of each of the tube sections, this will help to connect them together and make the painted textures flow more seamlessly.
