Unstable Holograms during remoting (VR Preview in editor) when a blueprint window is open. #27

Open shukenmg opened 2 years ago

shukenmg commented 2 years ago

Steps to reproduce.

  1. Download the repo at e7a21e859e2797d5881f3e5b383a22c0d960ec10 with UE4 4.27.1
  2. Setup remoting (HL2 using Holographic Remoting Player v2.7.0.0)
  3. Play the level in VR Preview, the holograms should be stable
  4. Open any blueprint (Either tabbed with the viewport or in a separate window, it doesn't seem to make a diference.)
  5. Play the level again, now the holograms are unstable and drift.

Probably because you lost focus on the VR Preview window and UE is conserving CPU cycles. Try switching to any other application and you will see the same thing.

If you uncheck this in Editor Preferences, it may stop that from happening: image

I have that option unchecked by default (And confirmed unchecked in the test project) so that can't be the issue.

In fact, opening a blueprint tabbed with the view port has the same issue, I forgot to add this detail in the post (I updated the repro steps). Like so: image
