Is there a way to export the entire scanned environment from a Hololens 2? Using the device portal, I can either export the closest 128 blocks as .obj, or what I assume is the entire dataset in .mapx format. I'd like to either export more than 128 blocks, export in sections but with a consistent alignment so I can stitch them together, or convert the .mapx to something else.

It is recommended you using Scene understanding SDK to query a static version of the spatial mapping data and save a serialized scene bytes to disk.
After scanning the room, invoke SceneObserver.ComputeSerializedAsync to serialize the scene as a byte array.
Microsoft.MixedReality.SceneUnderstanding.Samples is a Unity-based sample application that showcases Scene Understanding on HoloLens 2. And it shows up how to save any scene you've captured by saving the output of ComputeSerializedAsync to file: Line1154
Besides, the SaveObjsToDiskAsync function show how to save the Unity Objects from Scene Understanding as Obj files: Line1206
