[ARKit] 3D objects float above table


I’m slowly getting into AR development, and I started using Unreal with ARKit recently to give it a try, the first thing I did was load up the Handheld AR-demo scene. It works great, the cubes, spheres, and cones drop perfectly on tables and walls and all that, BUT, as soon as I replace those objects with 3D geometry, they consistently drop with about a foot of offset from the ground plane. Even with Unreals starter content geos (the yellow/chrome chair and those classics). The shadow still drops in the correct place, but the models are always offset. I’ve been looking around in every blueprint and tried tons of different models but they all end up doing the same, even though nothing has changed since using the original demo meshes.

Any ideas on this? I googled but could not find anything.
