I'm still just getting started, but already I can tell this is amazing. I've taken one scene that was flooded with in-world UIButtons and replaced it with a handful of these CanvasButton menus, which easily toggle contextually.
I haven't yet tried it out in VR, so I'm not sure how that works, but I see that it's supposed to be supported. How well that works for me may be a deciding factor whether I keep using this, but so far it's very promising.
As I mentioned in the Discussion area, my only main feedback so far is that I'd love support for UIButtonImage, to allow for condensed small buttons with just an icon, rather than solely relying on full text descriptions.
I'm not deep VR player so I just test in VR(quest2) and it's work
Yes, I also think image button is very great experience in scene. But I have some things that need to be dealt with recently, and the new version may take a while to be developed
