The role of 3D avatars has become increasingly important across digital media, virtual entertainment, social interaction, and immersive applications. Controlling the degree of realism in 3D avatars is therefore essential, particularly when transforming stylized characters into more lifelike representations. However, even when prompted for realism, score-distillation techniques often fail to produce realistic renderings of inherently stylized characters. This paper presents the first empirical investigation of score-distillation priors for controlling realism in 3D avatar generation, using anime-to-realistic transformation as an exploratory case study. We compare three score-distillation diffusion backbones: a baseline diffusion model, a low-rank adaptation tuned for anime aesthetics, and a pruned anime-specialized diffusion model. 3D avatars are generated for four representative anime characters, followed by quantitative and qualitative evaluation of realism enhancement and identity preservation. Experimental results show that the pruned model produces consistent improvements in perceived realism, achieving a 7.4% increase in CLIPScore relative to the baseline. This study offers insight into the role of score-distillation priors in enabling controllable realistic rendering for 3D avatars. |
