this is a ripoff of my translucent xl lora which i tried to retrain for flux already a few times and always failed.
it seems it works with snakes ;) and now also for a few other things... but dont be surprised if there are scales if you didnt prompt for them. its worse in recreate the subsurface scattering effect than the xl lora and looks overall pretty cgi but the addition of other loras could help ;O.

possible trigger are: sss, translucent, subsurface scattering
