Aligning Exported Chunk Models in Unity

[Joseph Brady]

Hi All,

I was wondering if anyone has had any experience exporting multiple chunks and lining them up in Unity or something similar?
I've created a large scan of a series of 12 islands.
Each island is a seperate chunk and they are all aligned using drone GPS coordinates.
Ideally I could merge the chunks into a single model and export that, however it is far too large to handle.
I've exported all the chunks separately as OBJs but understandably they have no relationship to each other and are just stand alone models.
Is there a zero point marker or something similar I could add to the chunks so I could align them or is there a different workflow for exporting a model as multiple chunks.
Any knowledge anyone has would be greatly appreciated.

If anyone else is curious a work around I found was to:

1. Add a marker to every chunk and set them to all to the same GPS lat and long
2. Export each chunk as an FBX with the Export Markers checkbox checked.
3. Import chunks into Unity.
4. Add an identical sphere or something solid at position 0,0,0 in each child Marker object.
5. Reposition all the parent chunks so all the child spheres snap together and line up.

A little laborious but effective. I'm sure someone else has a simpler workflow.
