Classes

CreateAnimationClipNode

This node will create an animation clip containing all the passed animation data.

CreateTextureGenerationSettingsNode.Inputs

The list of TextureGenerationSettings that can be driven from this graph node.

CreateTextureGenerationSettingsNode.Outputs

The output of the node.

This node will create Unity Texture from the texture paths provided (usually extracted from material usage in the usd file). It currently supports extracting textures from pgn, jpg, and exr file formats.

CreateTextureNode.InputPort

Input ports of the CreateTextureNode.

CreateTextureNode.OutputPort

Output ports of the CreateTextureNode.

DefaultUSD

Empty class used by non-imported USD files.

ReadBlendShapeWeightAnimationNode

This node will read skeletal blend shape weight animation The node has a single output: all the found animation for animated blend shape weights

ReadBlendShapeWeightAnimationNode.InputPort

Input ports of the ReadBlendShapeWeightAnimationNode.

ReadBlendShapeWeightAnimationNode.OutputPort

Output ports of the ReadBlendShapeWeightAnimationNode.

ReadCameraAnimationNode

This node will read transform animation data from UsdGeomCamera prims in the USD stage.

ReadCameraAnimationNode.InputPort

Input ports of the ReadCameraAnimationNode.

ReadCameraAnimationNode.OutputPort

Output ports of the ReadCameraAnimationNode.

ReadJointXformAnimationNode

This node will read skeletal joint xform animation from given bindings of UsdSkelAnimation to UsdSkelSkeletons The node has a single output: all the found animation for animated joints

ReadJointXformAnimationNode.InputPort

Input ports of the ReadJointXformAnimationNode.

ReadJointXformAnimationNode.OutputPort

Output ports of the ReadJointXformAnimationNode.

ReadXFormAnimationNode

This node will read transform animation data from UsdGeomXformable prims in the USD stage. It does so by asking for the fused local transform at each of the USD timecodes for which keys have been set. It will then convert this animation data into a format closer to what Unity AnimationClips expect.

ReadXFormAnimationNode.InputPort

Input ports of the ReadXFormAnimationNode.

ReadXFormAnimationNode.OutputPort

Output ports of the ReadXFormAnimationNode.

ResolveSkelBindingsNode

This node finds all the skeletons in the stage and populates structures that can be used later in the graph for animating joints and blend shape weights.

It does so by using the UsdSkelCache to discover skeletal bindings first, then going deeper in the stage to analyse the bindings that might not be resolved by the cache. This allows post-import re-binding and re-targeting of skeletal rigs and animation in Unity.

The Output structures are optimized to avoid duplication of the animation data. Skeletons can share the same animation, and so we only want to move one copy of the animation data through the graph

We only output bindings when there is animation.

The Outputted skinning query data are the ones that are under an animated UsdSkelRoot prim (the one that have skeletons that are animated)

The skinless skeletons are skeletons for which the cache was not able to resolve bindings, but for which we want to create game objects and animation for post-import re-binding and re-targeting

ResolveSkelBindingsNode.InputPort

Input ports of the ResolveSkelBindingsNode.

ResolveSkelBindingsNode.OutputPort

Output ports of the ResolveSkelBindingsNode.

SkinningQueryData

Structure encapsulating the skinning query data that is required by animation nodes. UsdSkelSkinningQuery objects have a limited lifetime bound to the UsdSkelCache object they come from We cache their data in order to use it later in the graph without having to move the whole UsdSkelCache object around

TrimTransformPathNode

This node trims the editor curve binding paths. When there is only one default prim and preserve scene root is disabled, no additional root is created, and the game object resulting from the root will be renamed by the prefab system, breaking the animation. Trimming the root's name from the paths keeps the animation valid.
