Hi, thanks for your comment!
Unfortunately, only the Elgato Cam Link is fully supported at the moment. Elgato seems to automatically block the video signal whenever VGC tries to access resolutions above Full HD (1080p).
Sadly, there is nothing I can do about this right now, as VGC relies on Unity's built-in WebCamTexture class.
To use VGC with your Elgato, I recommend sticking to Full HD. That being said, Elgato's own official software is actually great and works really well if you need higher resolutions! :)
