QUEST 2 specific : app freeze

Unity Engine
,
1

I’m experiencing an issue with the Quest 2, while the same build works fine in the Quest 1.
The app is starting fine but freezes(crashes) in a given context, then restart after the headset is woken up from sleep mode.

I’m actually trying to track the progress leading to the issue, and I’ve been able to gather this from the logcat :

Latest 2019.4.12f1 LTS, latest Oculus integration, Legacy XR, URP

An interesting thing to note, a ‘not so old’ previous version is working fine so I’m now in the process of downgrading things

Hi - did you manage to solve this issue? Seeing the same on my Quest 2 at the moment, only appears in il2cpp, ARM64 builds.

3

@sfaok if I remember well it was a custom shader+lighting issue

4

edit : I confirm, just found an old note :
“URP Additional pixel lights (+ shaders) = CRASH”

5

@Gruguir I’m experiencing this problem - can you provide a reference? or some more info on this?

nothing much, it’s old. It involved enabling/disabling a light at runtime (on a firearm) in conjunction with a custom shader.
