4.26? i don’t have that installed rn.
pretty sure it could handle a dynamic capture tied to the camera or your player character. update interval could be handled in blueprint. so you don’t recapture too often in static scenes. or you could use 2 captures and blend them. a kinda cheats to not make it “pop” too much on a lower update interval.
also… characters or npcs should have an option to not appear in this reflection capture if you don’t want it. the player should not be in it. but you could capture npcs to get them to appear in the reflection. depends how much detail you need for this armor reflection.
that’s what i can think of.
