Description

Hi,
Do you know how to load Qwen-Image-Lightning's acceleration lora in qwen-image-eidt-2509? In DiffSynth-Studio I loaded the acceleration lora and it shows 720 tensors are uploaded by LoRA, but the results were not right. if I set alpha=8, the results are all black, if I set alpha=1, the results are covered by heavy grids.
I use lora in "https://huggingface.co/lightx2v/Qwen-Image-Lightning/tree/main/Qwen-Image-Edit-2509", I've tried Qwen-Image-Edit-2509-Lightning-8steps-V1.0-bf16.safetensors、Qwen-Image-Edit-2509-Lightning-8steps-V1.0-fp32.safetensors, all wrong.
Do you know how to use it correctly? thx!

Research direction

Start by reproducing the reported Qwen-Image-Edit-2509 run in DiffSynth-Studio with the two named Qwen-Image-Edit-2509-Lightning safetensors files and alpha values 8 and 1. Compare the 720 loaded LoRA tensors and generated outputs; done means establishing a correct loading procedure that avoids black results and heavy grids.
