Did this so i could pinpoint the center of the map for building.
Due to multiple spawn nodes i had to mark them all (with spheres) and only after that put in the axis cross. Remove nodes/cross as you see fit. Might require the submaterial tool to display colors properly, otherwise nothing needed.
Before you ask, yea i know there's a map light on one of the spawn nodes. It was put there by the map author, can't change it.
