Merongmix2 is based on SD1.x(not 2)
NSFW and SFW both available
I have mixed the merongmix++ with some loras and some models.
The art style looks like mixing of merongstelmix and merongmix. (or not?)
I highly recommend using
highres.fix(or generation with high-resolution)
I usually upscale 640*960 to 1024*1536(or higher)
higher sampling step >40 (low sampling step for the second pass is OK)
Negative prompts "(low quality, worst quality:1.4)" or your negative prompt
