I’ve been building a game over the past few days, purely using the new UI tools - Canvas, nested images/sprites etc.
With my game viewport set to 1280x720, everything went great - until I exported at 1080p to see how it looked.
Unfortunately, it seems as though Unity does not scale the UI; at 1080p, it simply scales down the 1280x720 content… and expands the viewport to fill the rest of the area. Which basically leaves around 1/3 of the screen completely blank.
Worse still, if I lower the resolution, it just cuts off everything that doesn’t fit; so for exporting at 800x450 (standard 16:9 res for portals like Kongregate), around 1/3 of the game window vanishes completely. Further to this, if you edit the html, you can manually scale how large of a viewport you want.
I’m guessing this is something really mundane, as I’d be fairly surprised if Unity lost the ability to scale content 
unfortunately, I can’t see anything glaringly obvious - but I’ve noticed that the root Canvas’ width/height is matching whatever camera settings I input. Would someone be able to point me in the right direction of getting the canvas to scale appropriately?
edit: Seems I’ve gotton it fixed up for 16:9 resolutions by setting the canvas scaler to “expand” - however, if I leave the 16:9 resolution set, the viewport again expands/contracts and either reveals blank content, or cuts off content.
