Which versions are covered?

The following instructions cover the Unreal SteamVR plugin for Unreal Engine versions 4.25 and 4.26.

Before you begin

Before you begin, ensure the following preconditions are met:

Set up Evoke HMD object

In Evoke, create a new Smart Object. Ensure one of the calibrated Smart Object Templates (SOTs) for the HMDs is used.
Assign clusters to the Smart Object slots.
Ensure the Smart Object is tracking in Evoke.
Take note of the Smart Object name.

Tip
A subject is not required.

To set up Live Link, use one of the methods described in Create a Live Link source.

Ensure that the Blueprint from the previous set exists within the current level.
From the World Outliner, locate the Player Start asset.
In the Details panel, set the Z location to the floor (usually 20 in the default map).
Under Actor, locate Spawn Collision Handling Method.
Set the dropdown to Always Spawn, Ignore Collisions.
Note: Unwanted collisions with other Actors (e.g. a character) can cause unintended behavior.
In the Toolbar tab, locate the Play button.
Click on the dropdown next to the button and select VR Preview.
Tip: If this option is disabled, ensure that the VR headset is plugged in and the correct plugins have been set as described in Set up the plugin in the editor. You may need to restart the editor for this option to become available.
Put on the HMD and ensure the data is correct.
