<h3>⚔️ CROWN 3D Spatial Crossing &amp; Five-Finger Hilt Grip Master | MiniMax H3</h3>
[English] 
Trained by NineCrowns (<code>[CROWN]</code>) on 100% real-world human martial-arts &amp; dramatic blocking footage using an <code>8×NVIDIA B200</code> cluster (<code>Rank 64 / Alpha 64, Video-Only Blocks 10–49</code> with Ostris De-Distillation Adapter). 
This LoRA solves two of the hardest structural challenges in MiniMax H3 (Ref2VA / I2VA / T2VA):
<ol>
 <li>Five-Finger Bottom-Hilt Grip &amp; Rigid Unbending Blade Physics (<code>crown_grip</code>): Locks all five fingers cleanly around the weapon handle below the crossguard (preventing characters from grabbing the sharp blade edge or floating the hilt) and maintains ruler-straight, unyielding forged-steel blade geometry during linear cuts, thrusts, and edge-to-edge parries.</li>
 <li>Multi-Character 3D Foreground-Background Spatial Crossing Without Identity Swap (<code>crown_spatial</code>): Enables two characters in <code>Ref2VA</code> to charge past each other in an X-shaped foreground-background occlusion swap (Left↔Right position exchange) while 100% preserving each character's individual facial bone structure and outfit without face-swapping or clothes-bleeding.</li>
</ol>
[中文说明] 
由 NineCrowns (<code>[CROWN]</code>) 基于 100% 纯真人实拍武术兵击与双人走位素材，在 <code>8×NVIDIA B200</code> 集群上采用 <code>Video-Only (Blocks 10–49, Rank 64 / Alpha 64)</code> 架构与反蒸馏 Adapter 训练而成。专门解决 MiniMax H3 (Ref2VA / I2VA / T2VA) 的两大核心痛点：
<ol>
 <li>五指标准正握剑柄与刚性笔直剑身锁（<code>crown_grip</code>）：强制五指完整包握护手下方的剑柄（根除手抓剑刃、剑悬浮脱手），并在直线斜劈、刺击与十字格挡中保持刚性冷钢剑身笔直不发软。</li>
 <li>双人三维前景-后景 X 交错换位防串脸（<code>crown_spatial</code>）：支持双角色在 <code>Ref2VA</code> 模式下完成前景遮挡横向交错换位（如左男右女交错后换为左女右男），全程 100% 锁死各自五官与服装，0 串脸、0 换装。</li>
