OK.. suppose I create a flat sign with an East facing side and a West facing side. The East side has a texture that says EAST. The West side has a different texture that says WEST.
Suppose that when I rez the object (or if the object is inworld I approach it from a distance), I am viewing the EAST side and do not see the WEST side at all.
After a while, if i NEVER look at (move my cam) the WEST side, will the WEST texture load anyway? Or do i actually have to try to see it before the asset is loaded for my viewer?
Second part of this question... is the answer the same if my hidden prim face is loading new textures from scripts (e.g. a slideshow). Does my viewer need to "see" them or will they load even when hidden from cam view?
