 In this way, Fooocus 2.1.782 can benefit from all models and loras from CivitAI with both SDXL and SD1.5 ecosystem, using the unique Fooocus swap algorithm, to achieve extremely high quality results (although the default setting is already very high quality), especially in some anime use cases, if users really want to play with all these things.
 
-Recently the community also developed LCM loras. Users can use it by setting the sampler as 'LCM', sceduler as 'sgm_uniform', the forced overwrite of step as 4 to 8, and CFG guidance as 1.0, in dev tools. If LCM's feedback in the artists community is good (not the feedback in the programmer community of Stable Diffusion), Fooocus may add some other shortcuts in the future.

Do not forget to change the LCM lora weight to 1.0 (many people forget this and report failure cases). Also, set refiner to None.
