A small page about how to use decals on Spark Editor in Natural Selection 2
Decals[]
Decals can be use with a geometry plane (copy/paste the wall you want to draw a decal)
Also it can be used with the entity "Decals", see Spark_Entity_List
Keep in mind, geo planes will use alpha testing for transparency (eg no intermediate transparency, only opaque or fully transparent, so not so pretty looking).
r_decals[]
r_decals is a tool for ingame but it's currently desactivated in build 327
