Cybernetic eyes really aren't something any base models I've tried have been able to do. This gives you the ability to stick them on. Currently it has a pronounced swing towards a grimdark 40k style. Not so much an issue with 40k, but I may experiment with eliminating some of that for a future version.

Example images are most un-inpainted, with a few having a few minutes of extra work to show off what you can do if you go the extra mile. Any workflow not in the generation parameters is noted in a comment on the image.

Suggested Weight: 0.7-0.9

(different models are more resistant to the concept. If I go any higher than 0.7 with my model images start getting all John Blanche style stylized and contortion of faces. Brixel Core easily tolerates 0.8 without complaint, and needs it to really pick up the eyes.)

Main keyword is: bionic eye

Useful helper words: cyborg, cable, wires

Useful negatives: grainy

The LoRA is entirely capable of getting crisp eyes with a bit of inpainting, or if you get lucky with highresfix. I get the best results inpainting the eye at high resolution and lowish denoise, with enough padding to get the other eye in frame.
