Selecting the outside or inside of the cylinder –

Press F2 (MODE) to select one of the following.
FRONT & BACK: Output both the outside and the inside of the
cylinder.
FRONT: Output the outside of the cylinder only.
BACK: Output the inside of the cylinder only.
Note
When rotating a cylinder and showing the top and bottom open
ends on the monitor, there are restrictions on the rotation angle.
Ensuring smooth unrolling of a cylinder – F3 (ANGLE
RESET)
When unrolling a cylinder, with a rotation of the image applied
about the x- or y-axis, computational limitations of the processor
may cause a discontinuity as the radius of curvature increases, with
the image suddenly jumping in the z-direction to the completely
flat state. This problem can be avoided by using F3 (ANGLE
RESET).
First, with the cylinder unrolled to just before the state where the
discontinuity occurs, press F3 (ANGLE RESET), turning it on,
and create a key frame. Then increase the radius again, and repeat
the procedure as required. This makes it possible to obtain a
completely smooth unrolling effect.
