Why do you need to use xaml island?
Helix toolkit supports WinUI. Have you tried Helix toolkit WinUI package?
Probably it's more easier to just upgrade to winui3 than figuring out the xaml island.
2D controls in helixtoolkit have not been fully tested. Can you use wpf controls?
There's no much differences between mesh node and MeshGeometryModel3D. MeshGeometryModel3D is just a wrapper to provide dependency properties for mesh node properties.
Unless you need to use xaml bindings, otherwise there's no reason to do the cast.
Please upload a sample project. I am not able to reproduce this issue.
You need to calculate the center point yourself by calculating the center point of the geometry vertices loaded from your model.
Currently we don't support shadow for transparent object.
Yes, that's why transparent object shadow is disabled, currently we only cast shadow according to the outer shape of the mesh, not sampling the transparency according to the texture.
