It should :)
We tested a lot on ultrawide, but if not, please send a feedback back!

Have a stable flow of demon to kill

And there we have it, the texture size went from 4096kbyte to 85kbyte, so it has waaaay nicer memory footprint now.

The widget is a full screen one, and on 4K screen that resolution was kind of justificable, but it literally had the same ornament in the corner, so why not crop one of it, and solve the rest in the material? Fortunately the UV math for a 90 degree rotation was really simple and cheap.

Extra tip to end :
UI Materials are a bit funky Time-wise, and it is not using GameTime in the Editor. We had good results with that setup in the WBP

With these the UMG BP just sets two parameters and GPU solves all the rest.

I introduced a parameter for the play direction. It is 1 if Fade In, and 0 if Fade out.
For Fade I used a Lerp and OneMinus for switching the play direction.
For disabling the Rotation I just multiplied its local param with the IsActionVisible, effectively zeroing it if we are playing backwards.

The rotation had a specific curve originally that I replaced with some math.

Both features had different animation length: 350ms for the rotation sequence, and 100ms for the fadein/out.

The curves were simple enough to use simple math fortunately. That was the most complex one. But I am sure if it would get more complicated than that, I would go for curve atlases.

Last week I blew a dev's mind with that technique as we moved multiple animations to the GPU instead of having these as animation tracks in UMG on the CPU side.
