Animations
Bake Animations	Enable this when using IK or simulation in your animation package. Unity will convert to forward kinematics on import. This option is available only for Maya, 3dsMax and Cinema4D files. 当你的动画包中有IK或者simulation时选择这个选项。Unity将转换为前向动力学导入，注意这个选项只对Maya, 3dsMax and Cinema4D文件起作用。
Anim. Compression 动画压缩	The type of compression that will be applied to this mesh's animation(s) 选定网格体动画的压缩方式     来自 <>
Off	Disables animation compression. This means that Unity doesn't reduce keyframe count on import, which leads to the highest precision animations, but slower performance and bigger file and runtime memory size. It is generally not advisable to use this option - if you need higher precision animation, you should enable keyframe reduction and lower allowed Animation Compression Error values instead. 关闭动画压缩。Unity将不减少导入的动画帧，意味着最高的精确度。但同时意味着低的执行效率和更高的文件体积以及内存占用。一般情况下不建议这么做 - -如果你想得到更高的精确度，可以这么做：打开Keyframe Reduction、降低Animation Compression Error值
Keyframe Reduction 减少关键帧	Reduces keyframes on import. If selected, the Animation Compression Errors options are displayed. 导入时打开关键帧压缩，如果选择，Animation Compression Errors将不可用
Keyframe Reduction and Compression 减少关键帧并压缩	Reduces keyframes on import and compresses keyframes when storing animations in files. This affects only file size - the runtime memory size is the same as Keyframe Reduction. If selected, the Animation Compression Errors options are displayed. 导入时打开关键帧压缩、并且再次存储为文件时又压缩关键帧。这个选项之和文件体积有关 – 执行时内存与单独打开Keyframe Reduction时不变化。如果选择，Animation Compression Errors将不可用
Optimal	Used for generic and humanoid rig.
Animation Compression Errors 动画压缩误差	These options are available only when keyframe reduction or Optimal compression is enabled. 这些选项只有在"keyframe reduction"打开时才可用
Rotation Error	Defines how much rotation curves should be reduced. The smaller value you use - the higher precision you get. 定义有多少旋转轨迹将被去除。值越小，精确度越高
Position Error	Defines how much position curves should be reduced. The smaller value you use - the higher precision you get. 定义有多少位置轨迹将被去除。值越小，精确度越高
Scale Error	Defines how much scale curves should be reduced. The smaller value you use - the higher precision you get. 定义有多少缩放轨迹将被去除。值越小，精确度越高
