5.4 static mesh instantiation broken on quest 2 (or Android) ?

My project uses mesh instantiation to build a large cylinder on the fly with hexagons. Was fine in 5.3 but in 5.4, I get this results (started a new project VR, and instantiating the small cube a couple of times) shown in this video

using this blueprint:

Seems to work well in the editor. Anyone else has this issue or instantiation changed? Is it a packaging issue? Cheers.

Thank you for reporting! When you’re saying that it works well in the editor, do you mean using Mobile Preview or just regular SM5/SM6 rendering? Also, would you mind sharing if your project has MMV (Mobile MultiView) enabled? (This all helps narrowing down which code path has issues).

Oh! Why wasn’t I notify of the reply?? Sorry, for the late reply @RCL.

“When you’re saying that it works well in the editor, do you mean using Mobile Preview or just regular SM5/SM6 rendering?” Good question! Regular SM5/SM6 works well. Just tested with Vulkan and UE 5.4.2 and works well in editor as well. I repackaged with 5.4.2 for android (quest 2) and still have the issue.

My MMV setting is checked.

Thanks!
