View source for UnlitTwoTexture

* Two base textures are multiplied together and can be [[Material proxies|transformed]] independently. (Just like the [http://en.wikipedia.org/wiki/Blend_modes#Multiply Multiply] blending mode in typical image editors.)
* Unrelated to [[WorldVertexTransition]], which is used for making alpha fading transitions between two base textures on displacements.<br>

== Parameters ==
{{MatParam|$basetexture|texture|}}
The first Texture that is used, how it is used depends on the effects which are enabled.
By default <code>$basetexture</code> will be multiplied with <code>$texture2</code>.<br>
{{MatParam|$frame|int|The frame to start an animated <code>$texture2</code> on.}}
{{MatParam|$basetexturetransform|matrix|Transforms the texture before use in the material. {{VMT UVtransform}} }}
<br>
{{MatParam|$texture2|texture|}}
Second Texture that is used in different ways depending on which effects are used.<br>
By default <code>$basetexture</code> will be multiplied with <code>$texture2</code>.<br>
{{note|First texture is applied via {{ent|$basetexture}}.}}
{{MatParam|$frame2|int|The frame to start an animated <code>$texture2</code> on.}}
{{MatParam|$texture2transform|matrix|Transforms the texture before use in the material. {{VMT UVtransform}} }}
<br>
{{MatParam|$color|RGB matrix|tints the result, on brushes.}}
{{MatParam|$color2|RGB matrix|tints the result, on models.}}
<br>
{{MatParam|$beachfoam|bool|Introduced with Dangerzone, adds animated wave-like effects using a special texture|only={{csgo}}}}
{{important|This parameter is intended to be used with {{ent|$additive}}.}}
On the Dangerzone Wave Model, both <code>$texture2</code> and <code>$basetexture</code> use the 'Beachwaves' Texture.
{{todo|Do both Parameters need to use the same Texture?}}
The 'Beachwaves' Texture uses the RGB channels for different purposes.
<small>{{todo|Find a better Name for the Texture...}}</small>
* Red Channel : Waves Albedo Texture
{{todo|Can this be tinted using $color/$color2?}}
* Green Channel : Distortion/Noise for the Red Channel
* Blue Channel : Distortion/Noise for the Red Channel
{{todo|Further documentation required.}}
<br>
<br>
{{MatParam|$CrosshairMode|bool| Enables "Crosshair mode" using <code>$basetexture</code> for the Crosshair|only={{csgo}}}}
<code>$texture2</code> is used for a framebuffer texture.<br>
The result will be blended between <code>Crosshair Texture + CrosshairTint</code> and <code>Crosshair Texture * CrosshairTint</code> using <code>Average Luminance of $texture2 * $CrosshairColorAdapt</code>
{{MatParam|$CrosshairTint|RGB matrix| Tints the <code>$basetexture</code> when using <code>$CrosshairMode</code>|only={{csgo}}}}
{{MatParam|$CrosshairColorAdapt|float|Used for multiplying the average Luminance of <code>$texture2</code> <br>{{note|Default Value <code>"0.4"</code>}}|only={{csgo}}}}
