$envmap

The $envmap VMT parameter defines the environment map of a material, normally reflecting the nearest env_cubemap.

Basic VMT Syntax

"$envmap" <texture>

• This is the texture to use as the environment map (envmap).
• Normally <texture> is set to "env_cubemap".
• See also $envmapmask.

Additional Parameters

$envmapcontrast

"$envmapcontrast" <float>

• Controls the contrast (i.e. dynamic range) of the reflected $envmap.
• The parameter accepts a value between 0 and 1, where 0 is the normal contrast, and 1 is the full squaring of the color (color*color).
• Use higher contrasts to diminish relatively darker areas and increase "hot spots".

$envmapsaturation

"$envmapsaturation" <float>

• Controls the colour saturation of the reflected $envmap.
• The parameter accepts a value between 0 and 1, where 0 is 100% greyscale, and 1 is normal saturation.

$envmaptint

"$envmaptint" "[<float> <float> <float>]"

• Controls the tint (red, green and blue channels) of the reflected $envmap.
• The default is "[1 1 1]".

$envmapframe

"$envmapframe" <integer>

• Todo: ?

$envmapmode

"$envmapmode" 1

• Todo: ?

$envmapsphere

"$envmapsphere" 1

• Todo: ?

$basetexturenoenvmap

• Requires DirectX 9.

"$basetexturenoenvmap" <boolean>

• Todo: what does it do?
• Default is 0.
• See also $basetexture.

$basetexture2noenvmap

• Requires DirectX 9.

"$basetexture2noenvmap" <boolean>

• Todo: what does it do?
• Default is 0.
• See also $basetexture2.

$envmapoptional

• Requires DirectX 8.

"$envmapoptional" <choices>

• Sets the oldest DirectX version required for the shader to do a specular pass.
• Valid values are:
  • 80 (DirectX 8.0)
  • 81 (DirectX 8.1)
  • 90 (DirectX 9.0)
• Default value is 90.
