SD1.5 EpicRealism: the Stubborn 'Default Face'

#NSFW

This post is NSFW 19+ Adult content. Viewer discretion is advised.


EpicRealism, an early and excellent checkpoint model for SD1.5, tends to frequently generate a specific face type (primarily of Western Latin descent), characterized by thick eyebrows, sharp jawlines, or particular nose shapes, as a 'default' appearance. Even when strong positive prompts specifying other ethnicities or negative prompts are applied, the characteristics of this 'default face' subtly persist and often cannot be fully eliminated. In essence, it becomes difficult to use the model effectively for diverse facial generation.
