I used this back in 2019 for my first commercial mobile game, and it worked like a charm.

It works really well. If you need to use it for Canvas, you must switch from Screen Space - Overlay to Screen Space - Camera.

Easy to adapt into newer versions of Unity and fixes sooooo many screen compatibily issues

Easy to use, compact script that maintains a fixed aspect ratio even when Unity doesn't wanna. It's never been possible to enforce a fixed aspect ratio in Unity out of the box, and I've always had to resort to writing my own scripts to handle this. This asset does a better job with the math than I could have, adjusting for any situation you can throw at it. I may be using it incorrectly, but it appears to be changing the resolution every single frame, which is not ideal for performance, so it's worth swapping out the Update() function for OnRectTransformDimensionsChange().

I was not expecting it to work so easily and so well! Just add the object to your scene and done. Works for 3D. Note that if you have some hidden cameras, you should unhide them all and click "Find All Cameras in scene" from the script UI. You can hide them again after, and they will be letterboxed when activated in the game. This script should be built into Unity!

Works exactly as described, comes with example scenes that help you set it up. Can only recommend. Honestly don't know why this isn't something Unity can do out of the box...

Easy to use, works as shown, very nice!

Thank you so much, this is exactly what I needed so my game looks nice both in phones and tablets. In my cas I just needed to limit the vertial aspec ratio, so I modified the code slightly so only top/bottom bars ar added if needed, not lateral ones. ¡Thank you so much!

thx

As easy as creating one GameObject and you're done. Been using this since I started about 5 years ago, decided to leave a review because I owe the developer my carrer.
