    Hello everyone!

    I have a graph that has to be in local space for reasons. I'm calculating the distance between the player (represented here by a sphere) and any given particle in world space and send the result to a color lerp to light up the particle closest to the player:

    That's working fine as long as the graph sits at 0/0/0. Since the distance is calculated in world space, expected behaviour would be for the highlight to disappear as soon as I move the VFX graph out of range. But the highlight stays with the graph when moved, as if calculation would actually use local coordinates (also see attached gif).

    What am I missing here?

    Hello. I guess your player position is already in world space, so converting it from local to world space seems indeed wrong.
