Setting up camera and canvas in editor

Unity Engine
1

Hi All

Im brand new to Unity and I’m tearing my hair out trying to get my head around the first step of setting up my project and work space.

I want to set the editor up to work with my full res x4 assets which are designed for the ipad with a resolution of 2048 x 1536 px so I want my editor camera / UI canvas to reflect this, so that when I drag images / sprites from my assets folder, they appear exactly as they would on the device, I figured this would be an intuitive starting point and ensure that I position my UI and game objects correctly from the get go, ie as I see them in photoshop and other Image editing applications.

However After scratching my head for 2 days as to why my canvas was super large and the assets were either tiny or massive when dragged onto the canvas, I finally discovered the obscure wonders of PPU which is currently set to the default of 100

So Ive set my main camera up to

Orthographic

Size (7.68)
Viewport rect (W 4 H 3) (Im assuming this is the aspect ratio as its not very clear)

And my canvas to

Render mode (screenspace - Camera)
Render camera - (Main Camera)

Canvas scaler (scale with screen size)

reference resolution (2048 x 1536)

My Question is will this set up allow my game / UI to scale to other screen sizes when they run on the actual device. or am I stuck with the 2048 x 1536 resolution ?

The whole point of the Canvas Scaler is that your game will scale to other screen sizes, so I think you should be good.

But it’s not hard to test if you can make a standalone build for Win/Mac/Linux. Go to player settings for standalone, in the Resolution and Presentation group, click the box for “Resizable Window”. Then when you make a build, you’ll be able to resize the window while running just by grabbing the corner and dragging. Watch how your UI changes as a result!

Thanks Antistone Thats put my mind at rest a bit, Im having a lot of trouble getting my head around the Unity UI system and recttransform ect, The previous engine I used was simple coordinates relative to parent setup, with 1x 2x and 4x scale system, so I don’t trust anything I do with Unity UI, nothing seems to work as I intuitively think it should
I’ll test it out as you suggested.

Cheers
