Adding ObjectModel3D object to SciChart3DSurface.SceneObjects in codebehind

I had great success using ObjectModel3D objects in my XAML file. However, I would like to dynamically add and remove objects based on user input. For this reason, I’ve switched to using codebehind.

private void PopulateScene()
      {
          List<Uri> bitmapImages = DataProcessor.bitmapImages();
          Uri textureSource = new Uri(@"C:\Users\Will\Desktop\lemon_yellow__85006.webp");
  
          var rotation = new Rotation3D()
          {
              Angle = 45,
              Axis = SciChart.Charting3D.Axis.Axis3D.YAxis
          };
  
          foreach(Uri bitmapImage in bitmapImages)
          {
              ObjectModel3D objectModel = new ObjectModel3D()
              {
                  TextureSource = new TextureSource(textureSource),
                  Source = new ObjectModelSource(new Uri(@"C:\Users\Will\Desktop\EarthTile.obj")),
                  Position = new Vector3(1, 0, 1),
                  CoordinateMode = ObjectCoordinateMode.Relative,
                  Scale = new Vector3(2, 1, 1),
                  Rotation = rotation
              };
  
              using (sciChart.SuspendUpdates())
              {
                  sciChart.SceneObjects.Add(objectModel);
              }
          }
      }

I get the correct model with the correct texture. However, setting the position, scale or rotation doesn’t seem to work. All objects are in the same place ((0, 0, 0), no matter the coordinate mode), at the same (1, ,1 ,1) scale, and facing the same direction. How

I also have this function;

private void ClearScene()
{
using (sciChart.SuspendUpdates())
{
sciChart.SceneObjects.Clear();
}
}

Even after the object is cleared from SceneObjects, it persists in the chart.

This leads me to my 2 questions;

How do I get the objects I add to the chart to observe the
transformational parameters I give it? I don’t need to change the
parameters of objects after they’ve been added to the scene, just
before.
How do I remove objects from a scene?

I wonder how to bind SceneObject.

WPF ObjectModel3D SceneObject

I created an ObjectModel3D object in ViewModel and bound it to View, but the Scale and Position values are not applicable.
What’s wrong with my code?

View:

How does scichart add obj files to 3D interface

WPF ObjectModel3D

I followed the official example (SciChart_AddObjectsToa3DChart), created a simplest test program, copied the “King_Low.obj” file from the official sample program into my test program, but “King_Low.obj” did not show up, what is the problem?

Setting Opacity for ObjectModel3D

WPF ObjectModel3D SciChartSurface3D

I have a 3D chart where we are loading .obj files. If I set the opacity on the element in Xaml it works. However, we want to be able to adjust the opacity with a slider. When we bind the opacity to the value of the slider the opacity does not change. Is there something else we need to do to get the opacity to change when the slider value changes? The slider has a minimum of 0 and a maximum of 1.
