Asset Sync Settings

Properties	Description
Update Transform	updates the position, rotation, and scale of each GameObject.
Cameras	Create: create camera GameObjects. Update: update camera properties.
Use Physical Params	update physical camera properties.
Cameras	Create: create light GameObjects. Update: update light properties.
Meshes	create and update the MeshRenderer or SkinnedMeshRenderer component of applicable GameObjects.
Update Mesh Colliders	create and update MeshCollider properties of GameObjects which have meshes if the meshes are updated.
Visibility	enable/disable relevant components based on the visibility flag in the source data.

Tips: disabling Sync Meshes brings better performance, and is recommended if syncing meshes is not necessary, for example, when editing only the pose/animation.

Import

• Create Materials: finds existing materials based on their names using the Search Mode and applies them to relevant GameObjects.
  If the material is not found, then a new material is created.
  All materials are always added to the material list of the component.

  Search Mode	Description
  Local	search in the local folder of the MeshSync component.
  Recursive-Up	search starting from the local folder of the MeshSync component up to the Assets folder.
  Everywhere	search in all Unity Project folders.

• Overwrite Exported Materials

  Apply changes from dcc tools to exported materials that are referenced in the material list.

  Values	Description
  On	Apply changes to exported materials.
  Off	Do not apply changes to exported materials.

• Default Shader

  Use this shader instead of the default for the current render pipeline when creating materials.

• Animation Interpolation: sets the animation interpolation method.

  Values	Description
  Smooth	smoothly interpolate animation curves.
  Linear	do linear interpolation between neighboring animation keys.
  Constant	disable interpolation.

  For use cases in film productions, "Constant" may be preferable to match the number of animation samples to the target framerate on the DCC side.

• Keyframe Reduction: performs keyframe reduction when importing animations.

  • Threshold: the error tolerance.
    Higher threshold means less number of keys and higher errors, and vice versa.
  • Erase Flat Curves: delete curves that have no change (flat).

• Z-Up Correction
  Specifies how to convert Z-Up to Y-Up for data from DCC tools which have Z-Up coordinate system (3ds Max, Blender, etc).

  Values	Description
  Flip YZ	converts all vertices of Transform and Mesh to Y-Up.
  Rotate X	converts the root object's Transform to a Y-Up by applying a -90 X axis rotation to the root object, leaving the mesh in Z-Up.

  Flip YZ works better in most cases.
  For reference, Unity's standard FBX Importer does the equivalent of Rotate X.

Misc

• Sync Material List
  When enabled, changing an object's material in the Scene view will update the material list, and other objects which use the previous material will be updated to use the new material.

• Progressive Display

  Values	Description
  On	scene updates will be reflected while receiving data in real-time.
  Off	updates will be reflected after all of the scene data is received.

Material List

This material list holds all the materials that are used by this component.
Changing a material in this list will update objects that use the previous material to use the new material.

Import List and Export List buttons are used to load and save material lists.

Export Assets

Export meshes and materials into asset files, in order to reuse them in other scenes or projects.
Normally, meshes and materials hold by this component only exist in the active scene.
