Always snap to grid
From Unreal Wiki, The Unreal Engine Documentation Site
This zone kills pawns within it when triggered, and optionally changes their fatness and viewfog.
Some weirdness to note:
- default fatness is 128. Set DieFatness to smaller for thinning, larger for fattening but note that 0 doesn't work.
- viewfog is odd: it's a colour but defined by a vector. AFAIK it's taken as XYZ = RGB, with values 0 to 1.0
- The zone must be triggered before it will affect the players inside it.
See Message Placeholder for information on setting the death message.
