UX Components (Non-Canvas) — MRTK3

This package contains a library of UX components implementing the Mixed Reality Design Language using non-Canvas, non-RectTransform components.

You should decide carefully when choosing to use non-Canvas prefabs for your project. In the majority of cases, the Canvas prefab library will be more flexible, reusable, and maintainable, especially when you're building large applications with a large number of engineers and designers. In addition, the Canvas-based components offer modern design tooling that most designers expect to be able to use.. There are performance considerations as well, however: the flexibility and feature set of Canvas components can come at a higher cost. If you're building especially large UIs with several hundreds of elements visible at once, you may wish to choose non-Canvas prefabs for improved batching and draw-call efficiency.

The following table outlines a set of criteria you may wish to consider when choosing which components to use for your application. In addition, see the documentation for a detailed breakdown of how the hybrid Canvas UI systems work, with explanations on the corresponding advantages and drawbacks.
