$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".

Additional Parameters

Adjust overall reflection color & contrast

$envmapcontrast

"$envmapcontrast" <float>

• Controls the contrast (i.e. dynamic range) of the map.
• 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 saturation of the map.
• 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 components) of the map.
• The default is "[1 1 1]".

Specular masking

$envmapmask

"$envmapmask" <texture>

• Masks the map according to the alpha channel of the named <texture>.

$basealphaenvmapmask

"$basealphaenvmapmask" <flag>

• The default value is 1.
• Masks the envmap according to the alpha channel of the $basetexture texture.

$normalmapalphaenvmapmask

"$normalmapalphaenvmapmask" <flag>

• The default value is 1.
• Masks the envmap according to the alpha channel of the $bumpmap texture.

$envmapmasktransform

"$envmapmasktransform" <matrix>

• ?
• The default is "center .5 .5 scale 1 1 rotate 0 translate 0 0".
• DirectX 9 or HDR required. (LightmappedGeneric, VertexlitGeneric, UnlitGeneric)
• Also see $envmapmaskscale.

$envmapmaskscale

"$envmapmaskscale" <float>

• Scales the $envmapmask by the <float> value.
• DirectX 8 required. (LightmappedGeneric, VertexlitGeneric, UnlitGeneric)
• Also see $envmapmasktransform.

$envmapmaskframe

"$envmapmaskframe" <integer>

• ?

Other parameters

$envmapframe

"$envmapframe" <integer>

• ?

$envmapmode

"$envmapmode" <flag>

• Default is 1.

$envmapsphere

"$envmapsphere" <flag>

• Default is 1.

$basetexturenoenvmap

"$basetexturenoenvmap" <boolean>

• Default is 0.
• DirectX 9 required.
• See also $basetexture.

$basetexture2noenvmap

"$basetexture2noenvmap" <boolean>

• Default is 0.
• DirectX 9 required.
• See also $basetexture2.

$envmapoptional

"$envmapoptional" <integer>

• 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) and 90 (DirectX 9.0).
• Default value is 90.
• Requires DirectX 8.

$selfillum_envmapmask_alpha

$selfillum_envmapmask_alpha <float>

• Defines that selfillum value comes from envmap mask alpha.
• Default value is 0.0.
• Requires DirectX 9.
• A new parameter.
