How to make splats permanent?

[stan0033]

They are called splats right? the temporary textures drawn on the ground when you cast a spell.

Well, i want any effect to have permanent texture on the ground, just like i previously asked for corpses of units.

I see that in Decay - Effects Time 10000000s is not that.

I came up with that by watching YThunder Clap and Land mine explosion effects.
