It shouldnt matter at all what sampler, vae, checkpoint etc you use. It aslo doesn't need a trigger.

I use CFG 7, I set the weirght to 0.8 because thats a good weight for any lora for a person, i use clearvae, SDE karras, and i tested it on a couple differnt checkpoints and it seemed fine.

If thats not enough info I dunno what to tell you other than download it try it and if you like it cool if not cool, i dont really care and im sharing it only because others might like it, fame, fortune, whatever, i give Zeros about. Use it, dont use it, download, dont 0's
