The latest template on 0.4.5 still has the warnings (and includes line traces for line of sight interaction).
Other BP warnings are:
VRPlayerController
Warning InputAction Event references unknown Action ‘ResetHMD’ for InputAction ResetHMD
Warning InputAction Event references unknown Action ‘OpenMenu’ for InputAction OpenMenu
Info The execution path doesn’t end with a return node. False
Warning [0304.61] Compile of VRPlayerController successful, but with 2 Warning(s) [in 1,282 ms]
ExplorationCharacter
Warning InputAction Event references unknown Action ‘Sprint’ for InputAction Sprint
Warning Function ’ Set Master Pose Component ’ is unsafe to call in a construction script.
Warning [0367.79] Compile of ExplorationCharacter successful, but with 2 Warning(s) [in 579 ms]
There were also some depreciated SetStrings which can easily be replaced.
Also, on my rift, when I am sat down and looking in the game mirror the character pose is bent over and looking to the side slightly. If you start a game with the rift next to you on a table it also uses that pose as its starting pose so make sure you have it on your head before starting a game.
Saying all that, I love the template. Hope it is kept maintained.
