HolographicSettings SetFocusPointForFrame seems to make things worse [HOLOLENS]

Hey all,

I'm having issues with hologram stability.

I've got an empty unity scene with a plane world anchored 2 metres from the camera.

When SetFocusPointForFrame is not set, the plane is stable from a distance and fairly stable at arm's length.

When SetFocusPointForFrame is set, the plane oscillates at arm's length (1m - 50cm range) and at a distance.

The code is below. Please let me know if I am missing something, but it appears that setting a focus point makes things worse, not better.

Unity version: 2017.3.0p3
Windows SDK: 10.0.16299.0

Many thanks,

Harrison

Sorry, should have replied sooner. Have confirmed this is the same bug. Been told a fix is in the pipeline. Cheers!

 

Hi,
I'm having the same issue with hologram stability plane (using Unity 2017.3.0f3).
What version of Unity should I use which is not affected by this issue?

 

2017.2.0f3 should work for you, although it has some other bugs that could affect your project.
