Key features:

Cracked Skin & Surface: adding the cracked effect to everything that has some sort of skin or surface.

Usage: working nice with all kinds of portraits. Great for horror/halloween and post-apocalypse stuff. Kintsugi also looks very beautiful with it!

Sweet spot  & prompts: For optimal results, a higher strength (0,7-1,0) is recommend.
The LORA tends to realism and nudity, to avoid that some nice prompts and LORA strength ~ 0,3 is the way to go
(cracked skin, cracked surface, fractured, shattered, split, broken, damaged, craquelure...)

Findings: It seems to enhance images with complex patterns, floral-natural overgrown subjects, scaled surfaces, and net-like fabric. I guess it could also be used as a detailer for such specific “line-like stuff”

Combination Recommendation: Highly recommend combining it with Ultimator (0.5 strength on both), example images are all pure flux_cracked.

Let it crack!
