Hey,
I'm very happy to get in touch and also hopefully get some feedback/help. We are currently experiencing couple of issues when porting our application to Focus 3 using the WaveVR plugin for Unreal Engine. We might be able to workaround some of them but it would be great to know if they are known, solved or any thoughts on the matter. Setup
Unreal Engine 4.26 - WaveVR Plugin 4.1.1-r.3.1 - OpenGL ES rendering backend
VIVE Focus 3 Devkit - system 2.0.999.132 kernel 4.19.81-perf-dirty Issues
Whenever a Text Input field is focused an overlay input box appears and the screen darkens even though we have our virtual keyboard input system in place. Also this overlay is not properly stereoscopically rendered, appears in both eyes separately and is flipped upside down. We could never see it whole but it looks like some blank default with just an Input field and OK/Cancel Buttons.
I struggled to connect our DevKit to the PC correctly only to find out that some of USB ports don't interface with the device at all. There is a post on this forums that mentions that system version 3.+ would solve this issue and should be already release. The post was quite old and my device is still telling me that it is running the latest version of the system which is 2.0.999.132. Do I have an outdated device?
Changing WorldToMeters setting in the WorldSettings does not update the HMD transformation. We are using this value on other platforms to scale the world around the player up or down appropriately to his needs.
Is there a way to debug running application on the device?
Our shipping builds are randomly crashing in the OpenGL ES rendering backend. This is the issue we might not be able to workaround and I'm struggling to find out what is causing it. It looks like texture streaming code might suffer some race condition? Our project doesn't use anything fancy, no complex materials, only simple opaque and masked, no crazy texture swapping or custom render passes. The engine is clean without modifications. Any clue or idea is very welcome.
