Here is a typical example of how one might construct
a very nice GUI user interface that did a nice job of
hiding the boolean logic math that is going on behind
the scenes .

Reminds me of other landscape software's materials (is this WCS?)... slope
and altitude are omnipotent. Slope/altitude calculations are no problem for
VSL but things in RS are much less pre-determined than in this specialist
software, which has its pros and cons.
Boolean Logic ?
if A is less than X ... then R .
if A is less than X but greater than Y then G .
if A is less than X and also less than Y, then B .
if A is greater than x but less than Z ...
Well , you get the idea .
However , VSL does not seem to be all that Boolean-
friendly , from what I can gather .
You have a point: for example 'If' doesn't have an 'Else'.
Of course you can perform Booleans in VSL, but complicated stuff is tricky.
It does not seem to
like simple algorithmic formulas , either , from what I
can see although algorithmics are _somehow_ "do-able" .
Aaa-anyway , as we can see , if VSL will allow a simple
"if this slope/height" ..."then this texture/color/density"
suddenly we can envision a gui interface that allows for
user input regarding what color or what .png image will
be used for certain trees , and exactly how certain areas
will have it's bare rock displacement mapped .
Like I posted to Aidan, a single GUI is difficult with multiple materials
that rely on scope. I'll try to put it all into a single material and make
a user-friendly GUI for it with especially slope and altitude control. But
even this would depend on the mesh, the scene scale (bumpheight and
displacement are in 'world units'!) and other stuff.
Attack a mesh with VSL !!!!
