Performance requirements for mobile VR are extremely tight, and as such fullscreen image effects are often undesirable. The VRTunnellingProMobile component^[API] provides the tunnelling effect at much higher performance without using post-processing. To use, add the component to your player Character blueprint.

To achieve this, basic color, skybox and mask modes are available but more advanced features such as blur are not.

TIP: This effect uses the Iris Z-Rejection optimisation (see Background Modes) automatically unless the Mask Mode is enabled.

Platform Support

This version of the effect works on all supported platforms, mobile and non-mobile. It can work very well for desktop or console projects with a tight performance budget.

VRTunnellingProMobile on non-mobile platforms supports single-pass stereo, as does VRTunnellingPro. However it does not support single-pass stereo on mobile platforms. These include GearVR, Cardboard and Daydream.

Furthermore, while VRTP may work with Vulkan on some mobile devices, this is not yet officially supported and in general may not work.
