External Game View (EGV) is a workflow extension for the Unity editor which allows seamless powerful control of rendering content to external monitors.
We made this extension to:
Improve the in-editor creative feedback process by allowing fullscreen multi-display content rendering, which allows final designs to be tweaked accurately without having to make a build or squint into a scaled-down window.
Throw content up on large public screens (using multi-display pinning) in-editor without showing any signs of editor toolbars menus etc, so only the final canvas gets rendered.
Display very high resolution (more than 8K) content rendered 1:1 (without scaling) for better client preview.
To do this we had to get around some limitations of the Unity editor, and while there were a couple of good plugins for Unity that also allow fullscreen game view in some ways, these did not fit our requirements and thus External Game View was created.
At RenderHeads we use External Game View on a wide range of Unity projects, and believe we have made it easy to use, light on resources and seamless to integrate. We hope you will find it as useful as we have.
