$decaltexture

Template:Shaderparam It allows for a second UV channel to be defined for a model, allowing a decal texture to be placed on top of the base material. To use the parameter, the MDL must have been compiled from an FBX file and have a second UV channel defined.

Bug:Using VBSP's -StaticPropCombine parameter appears to break this effect on autocombined models in some cases.  [todo tested in ?]

Here, each label on the crates is laid out on a separate UV channel to that of the main texture – this allows easy and efficient reuse of the same labels/decals on many different props without losing texture resolution.

Parameters and Effects

$decaltexture $decalblendmode

* 0 = Alpha Masked

* 1 = Multiplied

* 2 = Modulate (functions like DecalModulate, or Photoshop's Overlay blend mode)

* 3 = Additive

Note:Mode 2 expects sRGB input, not linear. This means ~0.73 gray acts as the mid point, instead of 0.5

Note:If set to 1, $phong will not function on the material.

Bug:Mode 0 and 1 will not render in Hammer, however the basetexture will still render. Mode 2 and 3 will cause the model to render completely black in Hammer. It will still appear correctly in game though.  [todo tested in ?]
