Custom Vertex Attributes

Support for GLTF custom vertex attributes has been added. The following code snippet demonstrates how to export custom data to glTF:

public struct Vertex
public FVector3 position;
public FVector3 normal;
public FVector2 texcoord;

//Specify the Alias of this field to "_BATCH_ID"
[Semantic(VertexFieldSemantic.UserData, "_BATCH_ID")]
public float batchId;

  public Vertex(FVector3 position, FVector3 normal ,FVector2 texcoord, float batchId)
    this.position = position;
    this.normal = normal;
    this.texcoord = texcoord;
    this.batchId = batchId;

private unsafe static void ExportCustomFieldToGLTF()
//Prepare the vertices and indices:
  var vertices = new Vertex[]
    new Vertex(new FVector3(1, 0, 0), new FVector3(0, 1, 0), new FVector2(0, 0), 1),
    new Vertex(new FVector3(1, 1, 0), new FVector3(0, 1, 0), new FVector2(0, 1), 2),
    new Vertex(new FVector3(0, 1, 0), new FVector3(0, 1, 0), new FVector2(1, 0), 3),
    new Vertex(new FVector3(0, 1, 1), new FVector3(0, 1, 0), new FVector2(1, 1), 4),
  var indices = new int[]
    0, 1, 2,
    1, 2, 3
  //Convert the vertices into raw bytes
  var verticesInBytes = new byte[vertices.Length * sizeof(Vertex)];
  fixed(Vertex* pSrc = vertices)
    Marshal.Copy(new IntPtr(pSrc), verticesInBytes, 0, vertices.Length);
  //Create a vertex declaration from reflection:
  var vd = VertexDeclaration.FromType<Vertex>();
  //construct a TriMesh from raw bytes of vertices and indices
  var mesh = TriMesh.FromRawData(vd, verticesInBytes, indices, false);
  //create a scene with the mesh
  var scene = new Scene(mesh);
  //export the scene to a binary glTF file
  scene.Save("test.glb", FileFormat.GLTF2_Binary);

  // The GLTF primitive generated in the test.glb will be:
  // {"attributes" : {"POSITION" : 0, "NORMAL" : 1, "TEXCOORD_0" : 2, "_BATCH_ID" : 3}, "mode" : 4}

Improved GLB to U3D Conversion

Previously while converting GLB to U3D it resulted in wrong orientation. This issue has now been resolved.

Point Cloud Import

Added the Point cloud import support in USD/USDZ.

Point Cloud Export

Added the Point cloud export support in USD/USDZ.
