$alpha is a material shader parameter. It scales the opacity of an entire material by the given value. 1 is entirely opaque, 0 is invisible.
If any material on a brush has $alpha, the brush will stop affecting VVIS and become entirely transparent to NPCs from every angle.
This may be used with $translucent, although using $translucent here is redundant, as any $alpha different than 1 will already apply the $translucent parameter.
This cannot be used with $alphatest. If used, the material will be invisible.
