Update: this plugin and goran's Visual Mode Lua Physics are no longer necessary with Visual Mode 3.0. Use that instead!
VML Mute replaces the default monster activation and teleport sounds with silence. You will see the teleport effects, but hear only the ambient noises of the level.
A physics file to use together with visual mode lua. It stops the constant teleporting of enemies. It's universal and works the same on all scenarios. Enjoy a visual mode without distractions.
No sounds or visual appearances are made by monsters.
No slowdowns detected on my machine (2ghz pc, 4gb ram, 256mb graphic card) when I ran through a 1024 polygon solo level and activated all monsters.
