OBJ exported through batch is bigger than normal export

[Triplegangers]

Batch exporting multiple chunks, 7 million polygons each, using Batch Processing "Export Model" results in 900Mb files

If you export chuncks individually through the menu option Export Model files will be 534 Mb.

Used default settings for both options.

Hello Triplegangers,

It would be helpful, if you can specify, what are the export settings used for both cases: are normals, colors options enabled in both of them or not?
