"Adjacency information not built for static mesh" error but for Decals from Megascan

Hi, I’m building a game for Oculus Quest 2 (~ Android), the Megascan decals I placed in the scene don’t show up on the device.

I’m getting a lot of warnings like this:

Material: /Game/MSPresets/Decal_MasterMaterial/Decal_MasterMaterial.Decal_MasterMaterial
StaticMesh:/Engine/EditorMeshes/EditorSphere.EditorSphere
LogStaticMesh: Warning: Adjacency information not built for static mesh with a material that requires it. Using default material instead.

However, I’m using DecalActors and the only static mesh of a decal is the engine’s default sphere, and I’ve double checked it has Build Adjacency Buffer ticked.
In fact, I’ve checked literally every static mesh in my scene, all of them have Build Adjacency Buffer ticked.

I’ve also tried enabling/disabling Forward Rendering, and I’ve tried to set the master decal material (from Megascans) to Translucent and DBuffer Translucent Color (+/ Normal), none of which made a difference.

Anyone else encountered a similar issue?

Just happened too me. All meshes have BuildAdjecencyBuffer ticked. Trying to solve it now.
