Basic VMT syntax

"$translucent" 1

Additional Parameters

$additive

"$additive" 1
  • Renders the texture additively (Its colors are added to, instead of replacing, what is displayed behind it).

$alpha

"$alpha" <float>
  • Scales material opacity by the 'float' number.
  • Every pixel with an alpha value less than 178 will be completely transparent in game. However, values close to this value will confuse the shader at distances.(see $alphatest)
