Qwen: i'ts highly recomended to use 8 step lighting or more, 4 step can be glitchy.
in some cases, adjust the weight to 0.8 if you have problems with feet.

1.5: someone asked me to bring back the classic and realistic style of shadbase instead the comic ones.

you need the anime vae.

0,9 weight seems ok.

no need for prompt.
