Cloud

Cloud draws a $basetexture without lighting, masked by $cloudalphatexture.
As the name implies its used for rendering Clouds.
It does this by multiplying $basetexture with $cloudalphatexture, including Alpha.
This works similar to $detail's $detailblendmode 8, except the Alpha is also multiplied.
Unlike other Shaders, the RGB Values are not affected by Fog. The Alpha IS however!
By default, this Shader uses Alpha Blending ( $translucent ).
Using $additive, this can be reconfigured to draw additively instead.

Todo: The $cloudalphatexture uses a second Texture Coordinate.

Either this Shader is supposed to be used on Brushes ( utilising the Lightmap Coordinates somehow ),

or it's supposed to be used on planes created via the MeshBuilder.

Supported Parameters

$basetexture $frame $cloudalphatexture $cloudscale $maskscale $additive
