You have to use event tick with vinterp to… However this proves difficult somtimes because it has to be set every frame, because it moves to your position over frames. If you just do it once, it will only move it a small amount. For stuff like this i prefer to use the node, Move componenet to.
However if you insist on using vinterp to. You must use it with event tick
also make sure,
over time does not = 0
and delta time does not equal =0
