Valve's SteamVR Input Plugin

@anti_zer0

Thank you for the fast reply. I tried this and it didn’t help though

edit 1: I also tried re creating the anim BP from scratch. I noticed that the errors only occur if the anim BP is used by the hands mesh in my BP_MotionController. If I remove any reference to it the errors go away, which is strange.

edit 2: I just created a new blank VR project and the error isn’t happening.

edit 3: After deleting binaries, build, intermediate and saved, rebuilding the project in VS and fixing up redirectors some of the errors disappeared, but the nodes were still disappearing. I managed to create a new BP_MotionController and add a hand mesh with the Anim BP with no problems. I then tried to spawn this BP_MotionController from my VR pawn and now I get these errors:

edit 4: I have the project synced with my laptop (source control) so tried to implement it on there - same problem.

edit 5!!!: I tried spawning the BP_MotionController_2 from the level BP instead of from the VR Pawn and there’s no errors and no disappearing nodes. What on earth is going on??

Hi @anti_zero

Is SteamVR running properly during your editor sessions? A good indicator is if UE and SteamVR are communicating is the presence of the SteamVR logo in the toolbar.

Also, can you try the sample 4.24 project here: https://github.com/ValveSoftware/steamvr_unreal_plugin/wiki/sample/SteamVRInputPlugin_UEIntegrated.7z

BTW, I neglected to ask, are you upgrading a project or is this a new project in UE4.24?

Cheers,
