Spring RTS Engine

Hi, it would be cool, if you could specify a Mapdecal were a Unit marched over or a tanktrack rolled over the Map. For example On Ice or Crystall a crushedcrystall and blindglasTexture, that is copied inside the Footstep or Track. This way it would be possible to have the Ilusion of wet Earth benath a dry crust (important for Maps with many beachy Ilands...) or lava beneath thin Stone..
Or how about green gras, getting darker after a tank drove over it ?

LUA doable (pretty sure) with trepan's new tools.
I suspect people will be forced to start using LUA more and more for some effects.

For example I was looking at Panties' awesome new fx for weapons fire - its esentially a good-looking big dirt cloud. however it seems to only look good on brownish/greenish maps, so I am wondering if he'll have to hax some scriptz for it to look good on *all* maps, to perhaps taint the fx based on the main color fo the map.

maybe add a lua function that hooks into particle fx to get average color of the current area the particle is in?
