Export .orbx vs export as .obj (missmatch) why?

[glimpse]

ok, Latelly I've noticed an issue & I'm not so sure what is "right" anymore..

I've exported .orbx from 3dsMax (1.55) to opened in Standalone (2.14). Works flawless - at least I don't see anything different, but..
Then then selected & exported some newly created objects as .obj (scale leaving at 1)
& imported in the same scene that I've exported as .orbx - the scale is off, placement is off..?!

now that messed my head, mess my head 'bout scale & such - so, which scale is right? Exported as .orbx or as .obj?

Usually I model in 3dsMax (or any other app) & piece by piece export all models as I go, aranging scene in Octane Standalone from scratch..
(that worked so far, as I can render with standalone in the background while making mess, crashing modeling apps, etc..)

But how to export partly made scene, so that I could hook other (exported) models so the scale & placing would match?..

I probably miss something obvious or I don't understand some fundamental issue..

any comments would be welcome =)
