Traditionally, we have a ton of components for 2D UI, but the UX still sucks for the most part. I am not even sure what it will look like to create the 3D UX for anything other than the Games. For example, nobody uses Unity for desktop or mobile apps, because the freedom of a 3D environment isn't suited to regular UI tasks.
Vibe Coding is very convenient for creating this kind of content, especially in Gemini 3 Pro mode.
I think you could have the Agent add some color adjustment sliders to the tool, and then add a "Download" button so that others can export the content from the canvas with one click.
Sharing this in case others are waiting with this update like me.
