"WebMar 17, 2024 · For a cylinder, you'll more often want to use a cylindrical projection: Here, the U (x) coordinate of our UV is our arc-length around the cylinder, and our V (y) coordinate is the vertical position of the vertex. You can get the arc-length value by multiplying the total angle stepped so far (in radians) by the radius of your cylinder. " - Cylinder texture mapping
