How can I create illusion of moving skyboxes? I see this in Genesis of Descent wad. I need this to make illusion of move in my train. I try to move skybox viewpoint with action 229 and interpolation points, but when I change tag of skybox viewpoint from 0 to 1, skybox don't work.

Perhaps this old example from Gooberman might give you come clues:
