在二次元創作的廣大社群中，「腳控」與「腿控」一直佔有重要且專業的一席之地。對於腳底的褶皺紋理、趾頭的排列美感，以及腿部在不同姿勢下的肌肉線條，愛好者們有著近乎苛求的審美標準。然而，肢體末端——特別是腳部與手指的處理，長期以來一直是 AI 繪圖模型的關鍵挑戰。即便是在 SDXL 時代，當我們嘗試要求模型生成特定的腳底特寫或複雜的抬舉動作時，依然不時會出現多趾、比例失調或肢體錯位等崩壞現象。本次測試我們利用最新的 Anima Preview 3 搭配自訓的「萌芽娘」LoRA 模型，試圖挑戰這個號稱擁有最強自然語言理解力的 2B 參數模型，能否在這些高難度領域交出令老司機們滿意的答卷。
為了測試 Anima Preview 3 的極限，我們特別設計了十組涵蓋「居家、床上、公園、沙灘」等不同場景的姿勢提示詞。這類姿勢最困難的地方在於「主客體的互動邏輯」：當角色用手去抓握自己的腳踝或小腿時，模型必須同時處理手部的精細抓握動作、腿部的拉伸透視，以及從低角度（Low Angle）看過去的腳掌比例。這對傳統標籤堆疊式的模型來說是非常容易出錯的重災區。而 Anima Preview 3 憑藉著 1024 解析度的原生訓練與強大的 Qwen-3 語言編碼器，理論上能更精確地理解「誰在抓誰」以及「從下方觀察」的空間關係。這不僅是美感的測試，更是模型邏輯穩定性的深度壓力測試。
本次實測採取了「五抽一」的嚴格篩選法：針對每一組姿勢，我們連續生成五張圖片，並從中選出肢體比例最穩定、手腳互動最自然的一張作為代表。透過實測可以發現，Anima 對於腳部細節與裸足的細節表現確實相當細膩，尤其是腳趾的形狀與足弓的曲線，在 Preview 3 中展現出了跨世代的純淨度。配合 LoRA 模型對角色特徵的鎖定，即便是如此高難度的肢體動作，模型依然能維持極高的成功率與一致性。接下來，就讓我們透過這十組實測圖，一同鑑賞 Anima 在肢體構造美學上的卓越表現。
