I have a couple of separate BIM models that I have published as Building Scene Layers from ArcGIS Pro to ArcGIS Online. Individually, these work great.
However, it seems the Scene Viewer in ArcGIS Online doesn't let me display both of these models side by side, even if both layer's visibility is turned on. In the Building Explorer I can only select one (or none) that gets displayed:

I can view them side by side in ArcGIS Pro with no issue prior to publishing. How do I do the same in ArcGIS Online scenes?
