Is there a vertex limit on AR applications?

Hi All,

I’m having some difficulties with an AR application that I’ve been working on. In the editor, the scene I’ve created appears normal with no apparent defects however when I load the same scene on my device it appears that all meshes have become deformed.

My project uses a “stage” which is comprised of a number of objects created in blender which are imported into UE5 as a single static mesh. When viewing that mesh in the editor it appears normal as seen in the screenshot below, however the in-app view deployed using “Simulate on iPhone” appears totally distorted.

Device: iPhone 11 Pro
UE Build: 5.10

In editor

In AR
Ignore the clipping as that is just the camera clipping through the stage.

Any help with this issue would be greatly appreciated.

Is it that there is some form of vertext limit? Is it a limitation of my mobile device? Is it because I’m using “Simulated” instead of “Build.” Or is it something else?
