Ok, it does work with the "group by geometry" option checked, but I need to group it by color as well, because otherwise in Blender the colors are all over the place.

Thank you for reporting the issue. It is fixed now.

Hi, perfect, thank you 😃
I can´t test it, it says: "maximum import allowance reached for day." Is there a limit? I tried it quite often today, to test on which settings it works and on which it does´nt.

There's indeed a daily limit to prevent users from exporting the whole day. Tomorrow, there's a new day... 😃
