The second and fourth cylinders seem to be working okay but there is a small problem with the first and third cylinders.
Whats the difference what method would fix it?
btw blender version is slightly outdated (2.69) so i’m not sure if that would make a difference (just playing around with blender at work,not really allowed to download stuff)
