the best results are obtained by lowering the intensity of the lora (I personally use 0.5 if I want it to appear with other clothes or a value closer to 0.7 if I want it to come out with its game clothes), if the intensity is 1 it can generate images of shenhe as seen in the game unless the checkpoint or other lora prevents it.
in the tests I did it seems that the words "long hair" and "white hair" are necessary to make shenhe appear (although I don't quite understand why)
In the screenshots you can see different types of use examples that you can give to the lora :3
