Hey fellow LOD-creating vfx peeps!
Alessa (CodeKittah) made a nice tool that shows the distance between a selected actor and the viewport camera! A handy tool to see how far you away from an actor when testing its LOD’s!
Sometimes it can be a rather fiddling thing to move the camera in-and out of a certain LOD distance, especially with UE4 and LOD’s created in Cascade.
Luckily with this tool you can see exactly how far away you are from a selected actor, making it much easier to move in-and-out of a certain LOD’s activated distance.
