Accurate concealment options?

[Keltyrr]

Trying to figure out how to do some better concealment, since not everything is just 20% or 50% but I can't seem to figure out how to do it with the base system, or with any extensions I currently have. Any suggestions on what might allow me to fix this problem?

Within the base system there is only 20 and 50% :) But with the extended automation extension there is the effect VCONC with which you can adjust the percentage, as in VCONC: 30 (I think) :)

EDIT: Oh, Morenu was faster :D
