I’ve got a VR project that works fine in the editor but when I launch the packaged version then the motion controllers don’t appear (they still work because I can bring up the Steam interface and see the motion controller there). If I restart my level using a custom shortcut then the controllers appear fine and I can use my app. I’ve tried adding a delay for spawning the motion controllers but it makes no difference.

This is using the VR BP template Pawn and motion controller classes BTW.

Hello mr_pinc,

I have a few questions for you that will help narrow down what issue it is that you are experiencing.

Quick questions:

  1. Can you reproduce this issue in a clean project?
  2. If so, could you provide a detailed list of steps to reproduce this issue on our end?
  3. Could you provide screen shots of any blueprints/settings that may be involved with this issue?

I can reproduce the problem but it’s a bit different than I originally described.

If you set your Game Mode default pawn to be the MotionControllerPawn from the VR template level everything works fine.

If you have a different pawn (say spectator pawn) as your default but in your PlayerController you instantiate the MotionControllerPawn and make that the new pawn the motion controllers will not appear until you restart the level as I originally mentioned.

I am unable to reproduce this issue on our end with the information provided. Could you provide the example project that you used to reproduce this issue on your end?

I am having this issue. In the editor everything works fine. In the packaged build, it looks like the pawn never initializes. My pawn class never creates the controllers, but that is the very first thing it is scripted to do. Also, my HMD origin is well below the intended start position, and my orientation is flipped 180.

I have my BP_Pawn set as the default player pawn class, but I’m fairly certain it is not being created (or possibly just skipping BeginPlay?)

Any suggestions on what else I need to check?
