Hey @christopher.menzel
Welcome to the Speckle community! Feel free to Introduce yourself to everyone if you haven’t already and are willing to share.
If the camera position changes, the scene will need to re-render to have an effect. Depending on the surrounding code you may not be triggering that within the async event.
I’m not sure which demo you are looking at, but it could be as simple as adding viewer.needsRender = true for example.
