Signature:

Arguments:

• mode - Blend mode of the texture (string)
  • ADD - Adds texture color values to the underlying color values, using the alpha channel; light areas in the texture lighten the background while dark areas are more transparent
  • ALPHAKEY - One-bit transparency; pixels with alpha values greater than ~0.8 are treated as fully opaque and all other pixels are treated as fully transparent
  • BLEND - Normal color blending, using any alpha channel in the texture image
  • DISABLE - Ignores any alpha channel, displaying the texture as fully opaque
  • MOD - Ignores any alpha channel in the texture and multiplies texture color values by background color values; dark areas in the texture darken the background while light areas are more transparent
