This LoRA helps with faceless concept. Illustrious checkpoints can do this by themselves but oftentimes they produce shadowed anime style faces. LoRA was trained mostly on images generated with Pony of standard metal faceless robots, so grey color surface is default in this LoRA. Also some training images included twin from Atomic Heart(twin) and Tali'Zorah(tali) so their notable features pop up sometimes but those characters were not the main purpose of this LoRA, I just had a bunch of cool images with them. Oh, also you could use it with Adetailer to "erase" faces.
