The last Version of Renderman is usually sucks, my opinion, But the mod itself is scary and good.
I hope chrisbot would MAYBE release the older version that displays renderman somewhere around you, ONLY in dark, And some scary noises that are displayed.
The Last version have few bugs:
1: Renderman appears in day, few minutes after spawning when starting a server
2: Renderman is splitting to clones if the support is disabled, and he'll/they will walk after you.
3: The Detector doesn't work, either does the glitch gun, doesn't do any damage, or removes him.
4: The Original scary noises aren't displaying.
