How To Transfer Animation In 3ds Max

Actuate this option to export animation found in the scene and aggrandize this option to access advanced animation options and features.

Actress Options

Aggrandize Extra options to view boosted consign options.

Apply Scene Name

Unremarkably, the 3ds Max FBX plug-in saves the 3ds Max scene animation in the FBX file equally Take 001. Actuate this option if you lot desire the scene animation to be named after the 3ds Max scene instead.

This option is disabled by default.

Remove Single Key

When you activate this setting, the exporter removes keys from objects on export if the plug-in determines that the animation has merely i key. When 2 or more keys exist in the file, the keys are exported.

Note: Rotation keys are not afflicted past this setting.

Disable this option to consign every key to FBX, regardless of how many are found in the animation.

Note: This pick is disabled by default.

Bake Animation

This option lets yous bake (or Plot) animation at export time.

When you lot activate this choice all unsupported constraints and controllers, including the 3ds Max Biped, are resampled into blitheness curves. You can and so import these curves into another application that does not support these 3ds Max constraints.

The plug-in takes the Start and Cease values automatically from the "timeline" current settings of the host application. You tin can alter them by irresolute the values one time you actuate this option.

Note: Bake Animation Start/Cease/Step values cannot be saved in presets. The 3ds Max FBX plug-in always derives these values from the scene existence exported. For more, see Preset Broil Animation settings.

The Pace value defines how many keys are created per frame, and has a value of ane past default. Setting a Stride of 2 for instance, only bakes and exports a key every other frame.

Notation: The FBX Exporter will bake blitheness on any objects that have keys on FBX unsupported channels such as constraints, controllers, and and so on.

Resample All

Utilise the Resample all option to bake even supported blithe elements. This is dissimilar the Bake Animation option which selectively bakes unsupported elements only.

Note: The Resample all choice resamples animation using the frame rate of the host application. If y'all want the Resample all selection to utilise a different frame rate for sampling, yous must specify another frame rate setting in 3ds Max.

The Resample all option reacts to the state of the Bake animation option. If the Bake Animation pick is disabled, the Resample all choice is unavailable.

Deformations

Activate the Deformations choice to access the Skin and Morph deformation options.

Option	Description
Morphs	Activate this option to export all geometry Morphs used in your scene.
Skins	Actuate this pick to export all Skin deformations used in your scene.

Activate the Deformations option to admission the Skin and Morph deformation options.

Bend Filters

The Curve filters let y'all apply animation filters to function curves during the export process.

Constant Key Reducer

Actuate the Constant Primal Reducer filter to remove redundant keys. Redundant keys are keys that have the same value, which are equivalent to flat horizontal interpolations on a bend. Redundant keys are often a result of a resampled curve.

Before:

Afterward:

You lot tin ready specific thresholds for each type of transform (Transformation, Rotation, Scaling, and Other. Other includes Morph and custom attribute curves, for instance).

The default values are:

Values represent generic units. This is why you might demand to modify threshold values in relation to the world scale of your scene. This is true for very large or pocket-size calibration scenes.

If keys are numerically identical, use very modest values to ensure that no animation is lost.

If you use this filter to eliminate noise, for example, from move capture data, then you might need to modify values.

Setting	Clarification
Translation precision	Threshold for translation curves in generic units.
Rotation precision	Threshold for rotation curves in generic units.
Scaling precision	Threshold for scaling curves in generic units.
Other precision	Threshold for other curves in generic units.
Auto tangents but	This option ensures that but "auto" key types are filtered. Otherwise, keys with interpolation values greater than a certain threshold might be deleted.

Unroll Rotations

This filter re-evaluates rotation curves to reduce the number of 180' degree rotation jumps for a specified component. Y'all tin can modify or readapt these rotation jumps and/or Gimbal lock with this filter, and not affect the resulting animation visually.

Before:

Subsequently:

Note: The Unroll Rotations filter must resample the entire vector of a rotation bend (X, Y & Z components). This resampling lets the plug-in detect a new path of values that stand for the same rotation.

Setting	Description
Filter precision	The precision value affects how the plug-in re-evaluates the bend and defines the importance given to the unrolled curve. Actuate the Unroll Rotations filter to resample rotation curves and requite unroll priority and filter intensity to a specific component, X, Y, or Z.
Follow Y-up	Activate this selection to give priority to the Y component, normally used for Y-upward scenes.

Key Reducer

Activate the Key Reducer to reduce the numbers of keys on blitheness curves on consign. The Central Reducer reduces keys past automatically replacing them with tangents, which maintains the prevision of the animation while reducing the number of keys to speed processing.

You too can utilise this filter to reduce the number of keys on resampled curves, which lets yous edit keys, non dense data.

Earlier:

After:

Note: At that place is always a trade-off between the number of keys needed versus the precision of the animation. The more keys you take, the more precise the animation. The fewer keys you have, the easier it is to edit the keys, simply at that place is less precision.

Setting	Clarification
Filter intensity	Generic value. In about cases, the default value (1) is plenty to streamline the number of keys and proceed to remain faithful to the original visual issue. Note: Increasing filter intensity, for example to 4.0, removes more than keys, which speeds processing, merely results in much less accurate animation.
XYZ Curve Synchronization	This option adds keys to the other curves (10,Y, or Z) at every added key so that a key always exists on all three curves (Ten, Y, and Z) at the same vector for each fundamental over time. Note: This setting increases the number of keys, but is useful if you want to select a key on all curves at the same time. Game engines frequently crave this for real-fourth dimension animation playback.

The default values for the Key Reducer filter are a precision value of one.0 and the XYZ Curve Synchronization option disabled.

Point Cache File(s)

Activate this selection to create a cache file of a called choice set then you can retain vertex animation information during consign. To utilise this option, y'all must start create a pick gear up of the objects for which y'all want to retain the vertex blitheness in 3ds Max. Utilise the Selection Set menu to select an appropriate fix to consign the cache file.

The stored vertex animation data is stored in a folder in the same location as the FBX file.

Annotation: You must place the folder wherever the FBX file is placed, so that when an importer processes the FBX file, it will observe the Signal Cache data.

By default, any Point Cache files created are in .MC format. When you activate this option, three files are generated:

an FBX file
an XML file
an MC file

The 3ds Max FBX plug-in stores the XML and MC files in a subfolder named later on the FBX file and has the suffix FPC (_fpc).

For example, if you export a scene containing a cube named box01 to the FBX file myTest.fbx, you create the following files and folders:

myTest.fbx
myTest_fpc
box01.xml
box01.mc

The plug-in keeps whatever PC2 or MC Betoken Cache files that are already recorded (within the selection set).

What is Vertex Animation?

Object animation occurs when you motion a sphere from ane place to another. If you rotate or scale this object, it is nonetheless considered object animation; Any TRS animation on the object is considered standard object animation and is what is kept on regular exports.

Vertex animation occurs at the sub-object (vertex) level. For example, if you were to move 4 vertices on a sphere, this animation is lost on export unless you create a Bespeak Enshroud file for this blitheness.

What is a Indicate Enshroud?

A Point Cache is a local sub-object animation of an object. To export this local sub-object animation from a plan like 3ds Max, every vertex position must be evaluated and stored in a file or series of files chosen Point Cache files. Y'all must brand a choice set of the object(south) for which to store Point Cache information considering the exporter needs to know for which objects you want the vertex animation evaluated.

In 3ds Max, you lot create a Indicate Enshroud for your object(s) so you lot can have amend playback for complex animating. If, for instance, you had a scene with 20 controllers driving the animation of 500 different characters, creating a Signal Cache file would allow you store all the vertex animation and play information technology back on all 500 characters, so that 3ds Max does not evaluate the animation controllers for each character. This in plough, creates a more smoothen playback.

Characters

The Characters options let you specify how the 3ds Max FBX plug-in treats character and HumanIK information when you export.

True cat Characters as HIK

Activate the CAT Characters as HIK option when you want export your CAT rig every bit an HIK Skeleton Definition to an FBX file.

If this option is disabled, the CAT rig is exported as a skeleton with standard bones.
