This branch adds support for the lightx2v loras. https://huggingface.co/lightx2v/Wan2.2-Lightning is their repo, thanks to the lightx2v team.
Download normal wan2.2 models, ie:

And put them in the wan subfolder. If you already have them you could try inputting the location into the gui, it might work.
I have verified that these loras work with the i2v models so far.

This is the old lora, use it for high and low noise.
Use them in the wan2.2 tab and set sampling steps to like 4-8, Guidance Scale to 1 and use step_distill as the Sample Solver for old lora(single lora) or euler for the new lora(2 loras).
It seems like higher weights work better, 1.4-2 seems good for the old lora, 1.4High 1.0Low seems good for new one.
put the loras in the lora subfolder.
