http://geck.gamesas.com/index.php/Base_Effect that are Value Modifiers will cause a '+' or '-' to show in the PipBoy stats screens next to the corresponding actor values (SPECIAL or Skills) while the effect is applied (these are mainly from effects on Chems and other Ingestibles). I had been hoping that when I used a Script effect instead of a Value Modifier, I might get the same result when using http://geck.gamesas.com/index.php/ModActorValue, but that's not the case. From what I've seen now, it seems that a visible +/- on the stats screen means a true Temp AV modifier, and the only way to get a Temp AV modifier is with a Value Modifier Base Effect. Does anyone know for sure if that's the case, or if there's another way to apply Temp modifiers?
Also a question to any familiar with Oblivion modding, I'm just curious if this is different in Oblivion because on the http://cs.elderscrolls.com/constwiki/index.php/ModActorValue it states
"the changed stat is red or green to show a temporary modification". I assumed this would be anologous to the +/- in the PipBoy. So does ModAV work a little differently in Oblivion, does the UI indicate more than Temp AV modifiers, or is that note on the wiki wrong?
