FBX Importer - Animations Tab

Animations
Generation	Controls how animations are imported:
Don't Import	No animation or skinning is imported.
Store in Original Roots	Animations are stored in the root objects of your animation package (these might be different from the root objects in Unity).
Store in Nodes	Animations are stored together with the objects they animate. Use this when you have a complex animation setup and want full scripting control.
Store in Root	Animations are stored in the scene's transform root objects. Use this when animating anything that has a hierarchy.
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.
Animation Wrap mode	The default Wrap Mode for the animation in the mesh being imported
Default	The animation plays as specified in the animation splitting options below.
Once	The animation plays through to the end once and then stops.
Loop	The animation plays through and then restarts when the end is reached.
PingPong	The animation plays through and then plays in reverse from the end to the start, and so on.
ClampForever	The animation plays through but the last frame is repeated indefinitely. This is not the same as Once mode because playback does not technically stop at the last frame (which is useful when blending animations).
Split Animations	If you have multiple animations in a single file, you can split it into multiple clips.
Name	The name of the split animation clip
Start	The first frame of this clip in the model file
End	The last frame of this clip in the model file
WrapMode	What the split clip does when the end of the animation is reached (this is identical to the wrap mode option described above).
Loop	Depending on how the animation was created, one extra frame of animation may be required for the split clip to loop properly. If your looping animation doesn't look correct, try enabling this option.
Animation Compression
Anim. Compression	The type of compression that will be applied to this mesh's animation(s)
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.
Keyframe Reduction	Reduces keyframes on import. If selected, the Animation Compression Errors options are displayed.
Keyframe Reduction and Compression	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.
Animation Compression Errors	These options are available only when keyframe reduction is enabled.
Rotation Error	Defines how much rotation curves should be reduced. The smaller value you use - the higher precision you get.
Position Error	Defines how much position curves should be reduced. The smaller value you use - the higher precision you get.
Scale Error	Defines how much scale curves should be reduced. The smaller value you use - the higher precision you get.
