Composition layers allow 2D viewports to be displayed inside of the headset by the XR compositor through special projections that retain their quality. This allows for rendering clear text while keeping the layer at a native resolution.
|
||
|
|
[b]Note:[/b] If the OpenXR runtime doesn't support the given composition layer type, a fallback mesh can be generated with a [ViewportTexture], in order to emulate the composition layer.

The sort order for this composition layer. Higher numbers will be shown in front of lower numbers.
|

|
|
[b]Note:[/b] This will have no effect if a fallback mesh is being used.
