The $bumpmap shader parameter specifies the VTF texture to use for the 'bump' or normalmap of the material surface.

Basic VMT Syntax

"$bumpmap" "Path/NormalMapA" 
  • where Path is the filepath relative to game_directory/materials folder.
  • where NormalMapA is the filename; ie NormalMap.vtf.
  • Notice the .vtf file extension is not used in VMT texture references.

Additional Parameters

"$bumpmap" "Path/NormalMapA" 
"$bumpmap2" "Path/NormalMapB"
