The 3D cursor from Blender took me a long time to learn how to use properly; but once I did, it became one of the most powerful tools I had!
There were times when I was working in Unity that I realized how useful the 3D cursor would be in this engine...
So I made it myself!
This tool creates a gizmo completely hidden from your hierarchy so it won't get in the way. From the tool menu you can create, remove, or reset a cursor. From the right click menu, you can move the cursosr to your selection, or move an object to the cursor's location (based on pivots).
Everyone has those days where you can't be bothered to name your objects when sketching a scene, or you just get lost in the sauce and soon realize your hierachy looks like a complete mess and you have no idea where anything is.
This tool helps you quickly rename large lists of objects to more sensible names and keeping the project clean.
