Exporting .obj with high vertex count fails

[guzzard]

When trying to export an object as .obj with vertex count 3 424 770 it fails with this error in the console.

When going down one level to 856 194 vertices exporting works fine without any error in the console.

I'm afraid it's a browser memory limitation and I can't do anything about that.

OBJ is a text format, so it's not really performant/memory friendly when exporting.

If you find a browser app that can export a >~3M vertices model (in obj), I'd be interested to see it, maybe there's still room for improvement :)
