WindowImposter
WindowImposter
accepts only $envmap which is force drawn no matter the user settings or console commands used, like mat_specular 0
.
Note:Does accept some parameters in Garry's Mod, such as $alpha
Todo: Which parameters? Other branches?
The faces' orientation isn't taken into account when reflecting the cubemap, which makes it very convenient for making multiple fake skyboxes.
In Half-Life 2, WindowImposter is used by the material dev/dev_windowportal.vmt
, and used extensively on func_illusionary or func_brush entities in conjunction with func_areaportalwindow.
Warning:This shader only works on brushes.
Example VMT
WindowImposter
{
"$envmap" "space/space_envmap"
}
