  • Use in conjunction with $bumpmap to specify a second Normalmap VTF for blending materials on Displacement surfaces with the WorldTwoTextureBlend shader.
  • The percentage blend of each of the two textures is defined by alpha painting in Hammer.
  • This is the Normalmap equivalent of $basetexture2.
  • See Displacement for further information.

Available values


"$bumpmap2" "Path/NormalmapB" 
  • Specifies the VTF to use as the second Normalmap; eg NormalmapB.vtf
  • dx9


"$bumpmapframe2" ?
