VRDisplayCapabilities: maxLayers property
The maxLayers read-only property of the VRDisplayCapabilities interface returns a number indicating the maximum number of VRLayerInits that the VR display can present at once (e.g., the maximum length of the array that requestPresent() can accept.)
[!NOTE] This property was part of the old WebVR API. It has been superseded by the WebXR Device API.
Value
A number, which must be 1 if canPresent is true, or 0 otherwise.
Examples
See VRDisplayCapabilities for example code.
Specifications
This property was part of the old WebVR API that has been superseded by the WebXR Device API. It is no longer on track to becoming a standard.
Until all browsers have implemented the new WebXR APIs, it is recommended to rely on frameworks, like A-Frame, Babylon.js, or Three.js, or a polyfill, to develop WebXR applications that will work across all browsers. Read Meta’s Porting from WebVR to WebXR guide for more information.
