## IdolAnimInstance
UpdateAnimation每帧执行PrepareMocapParameters()，会获取TsMotionRetargetComponent的引用（正常情况会获取IdolActor的Controller中的TsMotionRetargetComponent。
TsMotionRetargetComponent，包含TsChingmuMocapReceiverActor => ChingmuMocapReceiverActor 。

1. 实现[[#Encode/Decode函数]]
2. HasCustomGBufferData()函数添加对应的ToonShadingModel宏判断
3. [[#FGBufferData新增变量]]
4. 在Encode/Decode GBufferData中新增逻辑。

1. Metallic/Specualr/Roughness => ToonShadowLocation/ToonForceShadow/ToonShadowSmoothness
2. AO => ToonSecondaryShadowLocation

4. PrecomputedShadowFactors => ToonSecondaryShadowColor
### Encode/Decode函数
RGB655 to 8-bit RGB。
将R 256 => 64 ,GB 256 => 32。之后使用2个8bit浮点来存储：通道1存储R与G的头两位；通道2存储G的后3位与B。
