They will generate on random soldiers, but should not generate on civilians.
I'm not sure why/if anyone would/will use this, but there it is.
How do I edit the config to stop these from apearing on crew?
Going on Assassin (Bully Hunter) comment that this mod is dead, can / should someone still use this mod for the other mods that require Invisible Heads as part of the required downloads or just not bother with any mod that requires this mod?
Can you do invisible arms/legs too?
Imagine getting head by this.
Also the empty heads could be added only to a particular race, reducing greatly this effect.
I think, if you compile the mod wit WOTC you can add a slider determining the frequency this parts appear in ramdom soldiers.
I've been using this with no problems my only real annoyance is that it pops up on engineers and scientists which you can't edit and can be seen in the avenger view.
