Perhaps you've been through Sebastian Lague's videos on procedural land mass generation? In his procedural planet generation series he applies noise to vertices already arranged in a sphere, rather than generating an euclidean space first and then warping it to fit a sphere.

Procedural Planets (E03: layered noise)

so you're just talking about a procedural generated texture map that you want to do in pieces? and you want to regenerate as you fly around the inside of the cylinder?

yes like the video link i share and sorry for the "cylinder" i most like in the video link in the game i can fly into the atmosphere of the ring to enter the world and fly out to a other world so i try to find a way to position my generated mesh into this shape like a big RING
