which sampler is recommended for this model? I've tried several common ones, but none of them work well.

looking forward to your suggestion
Hi, we use a scheduler with fixed denoising time steps. For the four-step model, we use fixed time steps of 1000, 750, 500, and 250. See lightx2v-run_wan_t2v_distill.sh.

This doesn't answer his question. We all know that LCM is the recommended Sampler, but what is the recommended Scheduler? Normal/Simple/Beta/Sgm_Uniform? This is the question.
Based on WanStepDistillScheduler it seems like you want linear. So for 4 steps (timesteps [1000, 750, 500, 250]) you'd want sigmas [1.0, 0.75, 0.5, 0.25, 0.0].
