Lists the images which can be used as craters in TS. Must be from the [SmudgeTypes] list and is in order of increasing crater size. This list is used by the Craters= and ForceBigCraters= tags in the ART file (see the ART.INI Guide).
The Craters= list is not used in RA2/YR, it exists solely as a remnant from TS, as such, deleting the line from [CombatDamage] has no effect. In RA2/YR, craters are left as a combination of warhead and damage dealt to the object occupying the cell.
Crater art follows building foundation rules, in that Height= and Width= (or lack thereof) will affect clipping. Valid crater shapes are 1x1, 1x2, 2x1, 2x2.
