Overview

The Material Editor is an engine tool available in Source 2007 and later. This tool allows you to edit VMT properties while in-game with via a simplified interface that is both user friendly and real time. This heavily simplifies the material editing process as well. Previously users would have to edit the vmt outside of the engine, then go back in-game and reload all materials, or the current vmt. To use it, run your game or mod with -tools -nop4 on the command line and select 'Material Editor' from the Tools menu. This tool is used to edit the material properties with the added advantage of a preview.

Note:This editor supports custom shaders, including ones from the Source Shader Editor !

Note: Make sure that sv_lan is set to 1 in the console located in the lower-left corner (sv_lan 1) if your game is MP based.

Warning:you need to use the command: "toolload vmt" in console for Alien Swarm to load
