Is there a way to add EffectShader (via script or magic effect) to the body without applying exactly the same, scaled down, shader to the face?

No matter how I setup this thing (EffectShader's CK settings and Photoshop texture positioning) it always appears on actors face.

take a look at the dawngaurd dlc monsters (demons) where the head is just a black void and what I think is supposed to be a swarms of flies. I am guessing it is an effect on a helmet. So you may be able to do the same thing in revers with just body armor.

Thanks, that was really clever suggestion. I have checked it, but unfortunately Keeper's head FX seems to be handled by scripted MGEF with Play.VisualEffect, aka something more andvanced than just simple shader. I checked some other mods using body EffectShader and they are also displaying them on face , makes me wonder if its really hardcoded?
