Virtual Animation Tools V6




Documentation: (discord has full development progress)

Release Notes: Discord

Are you tired of repetitive manual configuration?

Are you working on tens of thousands of animations?

Do you want bone layer blended for animation?

Do you want a more accurate distance matching curve?

Do you want to generate foot step Pos/Lock/IK curves(notify) automatically?

Do you want a tool that includes all the animation features?

Let “Virtual Animation Tools” help you solve them!


  • Add Bone (Add weapon bones, IK bones, camera bones and other unskinned weight bones)
  • Remove Bone ( Remove unskinned weight bones)
  • Add Animation Bone Data (Add or fix the bone data on the animation, such as adding the initial data of the fixed camera)
  • Modify Animation Bone Data (You can modify each frame of animation data, such as repairing animation jumping caused by too much value change)
  • Remove Animation Bone Data
  • Baking Bone Data

<1> Bake animation attack frame for low frame rate client or server

<2> Bake the specified bones. On the server, we can use this data to simulate the head and torso positions of crouching, crawling, etc.

  • Blend Animation Bone Layer (Similar to the animation node Layered Blend Per Bone)

<1> Convert arm animation to full body animation (FPS to TPS)

<2> Blend with other animations, such as repairing missing hand animations in motion capture animations, etc.

  • Constraint

<1> Constraining IK and FK bones.

<2> Copy the data on the IK weapon bone to the hand weapon bone.


  • Motion Curve (Distance matching curve, sample per-axis data on the root bone for distance matching)
  • Bone Curve (Support vector, transform curves)
  • Copy Curves
  • Transfer Curves
  • Sort Curve (Sort the curves in the initial order)
  • Remove Curve (Delete specified or clear all curves)
  • Output Curve (Export the specified animation curves data to an external curve asset,support float curve, vector curve)

Notify Tools:

  • Add Notifies (It is an instantiated data, which means you can modify your custom variable data here)
  • Modify Notifies(You can collect animation notifications used by current animation assets and modify their positions, variable parameters, etc.)
  • Remove Notifies(The specified animation notification class, location, notification track, etc. can be deleted in batches)
  • Add Notify Track
  • Modify Notify Track(You can capture the animation notification track names used by the current animation asset and modify them)
  • Remove Notify Track (it will delete all animation notifications on that track)
  • Generate FootStep Notifies(You can use this feature to automatically generate an animated notification that plays footstep sounds)

Montage Tools:

  • Montage Slot Modifier(Can be added, modified, deleted like the source engine)
  • Montage Loop Section (Set the section marked “Loop” fragment as a loop fragment, if the character is not found, set all fragments as a loop)

Asset Tools:

  • Crop(Can delete any range of frames)
  • Insert(Can insert a specified continuous pose to any frame)
  • Resize(Resize animation sample frame rate and length)
  • Composite(Multiple animation assets can be merged and blended)
  • Replace animation pose frames (which can fix animation assets that do not match the poses of the first and last loops)
  • Rate Modifier: Modify animation play rate and output the one rate asset.
  • Sample Motion Data

<1> Convert the motion capture animation to the root motion animation.

<2> Convert root motion animation to motion capture animation.

<3> Data of motion capture can be sampled and baked into the root motion after secondary adjustment

  • Convert Root Motion Data(Can scale the size of the root motion data, or sample the root motion data curves and perform secondary adjustment)
  • Motion Capture Reset To Zero(The initial position of the motion capture animation can be reset to the origin)
  • Generate LODs

<1> Can generate LOD with deformed data.

<2> Batch generation of LODs for multiple skeletal meshes.

  • Remove LODs(Batches)
  • Export(Export resampled animation assets, refer to the engine recording)

Mirror Tools:

  • Sample

<1> Mirrored bones can be selected, full body/upper body/local body

<2> Can choose to overwrite or create a new asset

  • Bone Tree(Automatically sample bone data to generate a mirrored bone tree, eliminating the need to manually configure bone information)

Retarget Tools:

  • Pose

PoseSearch Tools:

  • Distance(It will generate a unique value for each pose, which is a compressed pose password)
  • Animations(Each frame of animation A will be generated corresponding to the position of animation B)

GameFramework Tools:

  • Foot IK(Generate disabled or enabled footsteps IK alpha curve)
  • Foot Lock(Generate footsteps Lock alpha curve)
  • Foot Offset (which can be used to determine whether the footstep has shifted or not)
  • Foot Weight(Generate footsteps weights curve,Indicates whether it can meet the connection Stop animation, etc.)
  • Foot Position(Generate footsteps position curve,often used to distinguish between left foot or right foot)
