I have a cylinder that I want to make many loop cuts in so I can reshape it. (Loops cuts are around the perimeter, i.e. rings)

I'm using Blender 2.8.

Every tutorial tells me I can add a loop cut, press Ctrl-R or PgUp/PgDn and this will allow me to multiply the number of cuts.

This does not work for me. When I press Ctrl-R the cursor changes to two short black arrows - when I slide the wheel, the one ring slides up and down the length of the cylinder. (PgUp/PgDn does nothing at all.) Haven't found any combination of keys that will allow me to multiply the loops.

(I guess, failing anything else, I can always add additional cuts manually.)

  • $\begingroup$ Don't "click" after pressing Ctrl+R, then try scrolling the mouse wheel. The two black arrows don't appear until you "set" the loop by clicking the mouse - up until this point, mousewheel scrolling or pgup/pgdn should work fine to increase the number of "rings". $\endgroup$ Sep 29, 2020 at 3:55
  • $\begingroup$ You just press Ctrl+R only and the when the first loop appears just scroll down or up as per your choice of increasing or decreasing loops. $\endgroup$

It never worked like this in Blender 2.8+ (using PGUp/PgDn to adjust loops).
But you can use the pop-up menu, it gives you better control.
