Methods

BuildMesh(String, SanitizedMeshSample, MeshImporter.GeometrySubsets, GameObject, SceneImportOptions, Boolean, UsdSkelSkinningQuery)

Copy mesh data from USD to Unity with the given import options.

Declaration
public static void BuildMesh(string path, SanitizedMeshSample usdMesh, MeshImporter.GeometrySubsets geomSubsets, GameObject go, SceneImportOptions options, bool isDynamic, UsdSkelSkinningQuery skinQuery = null)
Parameters
Type Name Description
String path
SanitizedMeshSample usdMesh
MeshImporter.GeometrySubsets geomSubsets
GameObject go
SceneImportOptions options
Boolean isDynamic
UsdSkelSkinningQuery skinQuery

BuildSkinnedMesh(String, SanitizedMeshSample, MeshImporter.GeometrySubsets, GameObject, SceneImportOptions, Boolean, UsdSkelSkinningQuery)

Copy mesh data from USD to Unity with the given import options, setup for skinning.

Declaration
public static void BuildSkinnedMesh(string path, SanitizedMeshSample usdMesh, MeshImporter.GeometrySubsets geomSubsets, GameObject go, SceneImportOptions options, bool isDynamic, UsdSkelSkinningQuery skinningQuery = null)
Parameters
Type Name Description
String path
SanitizedMeshSample usdMesh
MeshImporter.GeometrySubsets geomSubsets
GameObject go
SceneImportOptions options
Boolean isDynamic
UsdSkelSkinningQuery skinningQuery

ImportSkinning(String, SanitizedMeshSample, Mesh, UsdSkelSkinningQuery)

Import skin weights and joint indices from USD.

Declaration
public static void ImportSkinning(string path, SanitizedMeshSample usdMesh, Mesh unityMesh, UsdSkelSkinningQuery skinningQuery)
Parameters
Type Name Description
String path
SanitizedMeshSample usdMesh
Mesh unityMesh
UsdSkelSkinningQuery skinningQuery
Remarks

JointWeights and JointIndices attribute should probably go into the MeshSample but we might not want to pay the deserialization cost if we don't care about skinning info. Although sanitizing the data would be easier if done by SanitizedMeshSample.Sanitize

ReadGeomSubsets(Scene, String)
