$envmap

Specular reflections.

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

This creates 'specular' reflections, for use on smooth surfaces.

Basic VMT Syntax

$envmap <texture or "env_cubemap">

env_cubemap is normally used, as it tells VBSP to substitute it for the name of the nearest env_cubemap entity when the map compiles. However, it is also possible to enter the name of a texture directly.

Additional Parameters

$envmapcontrast <normal>

Controls the contrast of the reflection.

0 is the normal contrast, while 1 is the full squaring of the color (i.e. color*color).

Tip:Use higher contrasts to diminish relatively darker areas and increase "hot spots".

$envmapsaturation <normal>

Controls the colour saturation of the reflection.

0 is greyscale, while 1 is normal saturation.

$envmapmask <texture>

See $envmapmask.

$envmaptint "[<red float> <green float> <blue float>]"

Controls the colour tint (red, green and blue channels) of the reflection. Any positive number can be used.

Default value is "[1 1 1]". You must use quotemarks.

Tip:This command is useful for controlling the brightness of a specular reflection without an $envmapmask.

$envmapframe <integer>

The frame of an animated texture to use for reflections.

$envmapmode <int?>

Todo: ?

$envmapsphere <bool>

Todo: Probably related to using spheremaps instead of cubemaps. How is this useful?

$basetexturenoenvmap <bool>

$basetexture2noenvmap <bool>

Todo: What do they do?

Require DirectX 9.

See also $basetexture and $basetexture2.

$envmapoptional <choices>

Sets the oldest DirectX version that should draw the reflection. Choose from:

• 80 (DirectX 8)
• 81 (DirectX 8.1)
• 90 (DirectX 9)
• 95 (DirectX 9 with Shader Model 3)
• 98 (DirectX 9 with DirectX 10 hardware)
