I'm trying to use two cameras at the same time with the ArcGIS SDK for Unity, and I'm getting the following errors:
One camera is rendering to Display 1 and the other one to Display 2. I'm using a Normal project converted to HDRP and Unity 2021.3.4f1. I have tried to create an empty scenery, add the ArcGIS map and add two cameras using the menu ArcGIS offers for it, with the same result.
You can only have one active ArcGISCamera component in the scene at the same time. The ArcGISCamera component controls what we render. So if you want to have 2 cameras you can have one with the ArcGISCamera and the other can be a standard Unity Camera.
That error message can be improved upon so I'll make an issue for us to resolve that.
