AtomicX ! i have try ! but with animated object the cubic map on the static scene objects don't change
Only update once every X frames. You missed the point of what I said though. Cube maps are generally static, normally in post games, if you approach a cube mapped object, or the scenery changes, it isn't updated. Look at the reflective water in some games, and you'll notice that it doesn't always update to reflect its environment, because that would be processor intensive.
Another option would be to hide as much as possible when rendering the sides for the cube map.
