Now go back to the Modify tab, right-click on "Loft" and choose the Convert to: Editable Poly option (Fig.09).
Go to the Modifiers drop-down menu, scroll down and pick Unwrap UVW from the list (Fig.10).
Expand the + and choose Face. Scroll down and click the Point to Point Seam button (Fig.11).
Click on one end of a long edge, then on the other, and it'll highlight all the connecting edges between (Fig.12 - 13). We are creating a seam for the pelt mapper to use in a minute.
Select any one face on the tube and click the Exp. Face Sel To Pelt Seams button (Fig.14). Weee! That's so much faster than selecting it manually. Nice button!
Click the Pelt Button (Fig.15). You can adjust the initial planar map that it throws on by clicking on the Align X, Y and Z buttons, but it's not totally necessary. Then click the Edit Pelt Map button.
