First, thanks for the bug report.
The VFX Demo project includes a uEye camera box and it seems the driver for the uEye camera is not installed on your computer. It is normal. They are third parties, they are not included in the installer. But the driver should be installed if you want to use that box.
We recommend installing the IDS uEye Cockpit (https://en.ids-imaging.com/ueye-cockpit.html) and the IDS Camera manager (https://en.ids-imaging.com/ids-camera-manager.html). Both are installed by default on the RealMotion servers.
However, if you don't have an uEye camera or if you don't want to install the drivers, you may simply override the box by doing these modifications on the graph:
In this example, I removed both the uEye and the SICK laser, but you may choose to kept the SICK device if needed.
