Describe your enhancement suggestion in more detail

Titanfall 2's shader implementation includes support for VScript functions that can be called directly by a VMT file which return a value for use in proxies, as is the case in this particular example from Titan/Pilot cloak variables:

    "Proxies"
    {
        //CHange the alpha base off of script input
        "EntityScript"
        {
            "scriptFuncName" "VMTCallback_GetCloakFactor"
            "resultVar"    "$cloakAlphaScale"
        }
    }

Other examples making use of this feature include weapon ammo counters and in-game HUD elements.

A similar implementation of this feature could potentially be added to Strata.
