TL;DR: Effective upscaling of the Anima anime-style model requires low denoise thresholds and careful selection of non-anime upscale models to avoid visual artifacts.
Summary: Community findings indicate that upscaling the Anima model with USDU is highly sensitive to denoise settings, requiring levels as low as 0.05 to prevent unwanted alterations. Additionally, utilizing general-purpose upscalers like 4xNomos8k rather than dedicated anime upscalers yields better results for painterly or complex styles by reducing artifacts.
Why it matters: It provides practical workflows for creators upscaling high-fidelity anime model generations without losing style integrity. AI artists should test low denoise configurations (0.05 to 0.15) and match their upscale models to the specific art style rather than the model type.
