Great break down. The UI material lab has some great UI material examples. Saved me a ton of time remaking a performant better UI

Did this with very complex widget (with hundreds instances) over a year ago and performance boost was big. Also, object count should be lower if using a single image inside a User Widget.

Also, performance widgets like invalidation boxes (including Cache Relative Transforms) can make a massive saving by controlling render rates.

Question, Do I need to worry about having a deep hierarchy if there's only 1 instance of the widget created when the game first loads ? For example in the pause menu thats never destroyed only collapsed and shown ? I'm wondering this because the way I have things now my pause menu is pulling in my settings menu which has dozens of nested widgets and a very deep hierarchy ... But if my understanding is correct this is only a concern when creating the widget to prevent stutters ? Thanks for the help. EDIT : The settings menu also pauses the game so in theory that would free up alot of performance when it is displayed I would think or am I wrong there ?

Where is the link for the Epic talk you mentioned at the beginning of the video? Thanks

So it's all about the drawcall count, caused by a simpler hierarchy? Or am I wrong

Got a tutorial on how you made that thruster?
