ROTATION not working on IconSymbol3DLayer

[MichaelK1]

I want to rotate the icon symbol like (in SceneView): 

symbol: {
    type: 'point-3d', // autocasts as new PointSymbol3D()
    symbolLayers: [
        {
            type: 'icon',
            size: 8,
            resource: {
                href: './assets/images/triangle.png',
            }
        },
    ],
},
visualVariables: [
    {
        type: 'rotation',
        field: 'heading',
        rotationType: 'geographic',
    }
]

My Feature layer elevationInfo mode is : on-the-ground

But it's not working, is it possible to rotate an icon based on visual variable?

If not how am I supposed to do this?

Thanks

Hi Michael
This is a known limitation and mentioned here: https://developers.arcgis.com/javascript/latest/api-reference/esri-renderers-visualVariables-Rotatio...

"In a SceneView rotation visual variables are not currently supported with marker symbols, text symbols, 3D icon symbol layers and 3D text symbol layers."

You could use ObjectSymbol3DLayer . See also the sample:
https://developers.arcgis.com/javascript/latest/sample-code/layers-featurelayer-labeling-3d/

Would that work for your use case? Otherwise can you let us know what your use case is.

Thanks.

Hi Sascha

Thanks 

I could use ObjectSymbol3D objects for displaying 'my triangles' (with the correct rotation). But these 3d objects have a fixed size based on the map. Is it possible to scale those like markers?
