> But if my ViewportLeft has a negative value, it doesn't work.
It works to me
Could you show a screenshot?
What works for you?
So, I can't rebuild the negative ViewportLeft value, but here is a screenshot...
In this case, I have a screen with 1000 pixel width and 1600 pixel height. But the ViewportRight value is 1080 pixel and the ViewportBottom is 1824 pixel. That's make not sense for me. In this case, how can I calculate the position of the right edge?
Check out the Anchor behavior to use with the scale outer, as well as double check the layer the ViewportLeft("layer") is using?
I'm not using the anchor behavior. I use ViewportLeft("Layer"),that's correct.
in my games I always use this I have no loss of image quality, the game is lighter and the components are always on the screen
That's working only if you have a 16:9 ratio. Samsung S9+ and Mate 20 Pro dosen't have this ratio. The Black bars appears. I think "letterbox scale" is not the solution, because the name says it all.
