UE 5.5.1 v74 - Oculus Quest 3 not generating the PSO .upipelinecache file
We are using the Meta Fork of UE, 5.5.1 v74. I've followed through every single piece of online documentation I could find on how to get the PSO cache to work on the Quest 3. Nothing works. No pip...
After much digging, I've figured it out. There is an Vulkan setting that needs to be turned on to enable the legacy bundling method.
r.Vulkan.EnablePSOFileCacheWhenPrecachingActive=1
With this on, the CollectedPSOs folder does get created along with the upipelinecache file. This flag works in both 5.5.3 as well as 5.5.1.
I had setup and bundled PSOs on a PC based UE 5.1 project last year, so I was hoping it would still work even though it is now 'legacy'.
I was following the steps for an Android build contained within:
For me, using the Project Launcher never loaded past the initial splash screen with either ASTC or ETC2 cooked builds.
I was able to use the UnrealAndroidFileTool to modify the UECommandLine.txt to add the -logPSO to an installed build that had all of the required project settings. Upon running this build, no CollectedPSOs directory was created.
I'll be trying the new method today:
I'll update this thread with my results.
I would also try to launch a game via command line:
1. Make sure headset is connected in debug mode
2. Modify this command to your your project name, company name
adb shell am start -n com.YourCompany.YourProject/com.epicgames.unreal.GameActivity --es "cmd" "-logpso" this should start you latest packaged build, with pso logging enabled, in theory.
Generated pso file will be in your saved folder on quest
