VR大空间资料 02 —— 常用Body IK对比

省流总结：

笔者使用Mimic IK VR Body System，此插件可以整合进VRAF和VREP框架中，能正常打包apk。

DragonIK，动画同事用的多。

BodySync IK，无法打包android。

VR Body in BP (Synced) ，没用过不了解。

Ynnk IK Body，Pico手腕默认折90°，暂时没找到如何修改；UE5.2手指抓握动画Bug；UE5.3、UE5.4缺失关键手指相关的骨骼旋转蓝图节点

Mimic Pro IK Body System（配合VREP网络复制）

整合VRAF框架

可以修复Pico手腕弯折Bug，

BP_VRBodyComponent中偏移量改为000，不用断开Disconnect for VR Expansion Template（修改手碗偏移量）
