Incorrect Node.Name after export + import binary FBX introduced in 21.9.0

Aspose.3D Product Family
#1

Noticed this when upgrading from 21.6.0 to 21.10.0. I’ve isolated it to 21.9.0

Following code should show the issue:

[TestFixture]
public class Tests
{
   
    [ OneTimeSetUp ]
    public void Setup()
    {
        var l = new License();
        l.SetLicense(@"<my license file>");
    }


    [Test, Parallelizable(ParallelScope.All)]
    public void SimpleScene_SaveAndOpen_FileStream_Successful([ValueSource(nameof(FBXTestFormats))] FileFormat fileFormat)
    {
        Scene scene = new Scene();
        var cubeNode = scene.RootNode.CreateChildNode("Cube Node");
        cubeNode.Entities.Add(new Box(10, 10, 10).ToMesh());

        string fileName = Path.ChangeExtension(Path.GetRandomFileName(), ".fbx");
        string temporaryFilePath = Path.Combine(TestContext.CurrentContext.WorkDirectory, fileName);

        using (var fs = File.Create(temporaryFilePath))
            scene.Save(fs, fileFormat);

        Scene openScene = new Scene();

        using (var fs = File.OpenRead(temporaryFilePath))
            openScene.Open(fs, fileFormat);

        Node outCube = openScene.RootNode.GetChild("Cube Node");
        Assert.NotNull(outCube);
        Assert.NotNull(outCube.GetEntity<Mesh>());
    }


    public static IEnumerable<FileFormat> FBXTestFormats()
    {
        yield return FileFormat.FBX7500ASCII;
        yield return FileFormat.FBX7500Binary;
        yield return FileFormat.FBX7400ASCII;
        yield return FileFormat.FBX7400Binary;
        yield return FileFormat.FBX7700Binary;
        yield return FileFormat.FBX7700ASCII;
    }
}

Happens for binary formats only. ASCII is fine.

Hi

I noticed there is a 21.11.0 release in the release notes here: https://docs.aspose.com/3d/net/aspose-3d-for-net-21-11-release-notes/

But no package on nuget yet: https://www.nuget.org/packages/Aspose.3D/
21.10.0 is still the latest

Eager to use the latest with the fix! Thanks

The issues you have found earlier (filed as THREEDNET-988) have been fixed in Aspose.3D for .NET 21.11.

@bortos

The latest version would soon be available on NuGet Gallery as well. We will let you know as soon as it is uploaded there.

I have a set of tests setup and 21.11 still has the node name issue with FBX 7.7 Binary

The issues you have found earlier (filed as THREEDNET-1001) have been fixed in Aspose.3D for .NET 21.12.

#10

21.12 doesn’t target netstandard2.0 anymore, is this going to be the case in future?

#11

@bortos

The support for .netstandard 2.0 was replaced with 2.1 and it will stay like this in future. It’s some optimization in RVM. The MemoryExtensions.AsSpan are supported in netstandard2.1, but not netstandard2.0. We will try to add support for both 2.0 and 2.1 in next version.
