SparkEdit
From Halo Mod Maps Wiki
Introduction
SparkEdit is the tool we use edit maps. It has a duplicate function to add vehicles (if that vehicle is on the map) and scenery and a teleporter creation feature to create teleporters.
Why we use it
We use SparkEdit because it is a very powerful and easy to use tool for modding our maps.
