Problem with parts and variants after export

[ARBusMods]

Hello,
I am having problems with the variants and their respective parts when exporting a model from blender.
Within the game, some components are distributed randomly towards some of the parts, which breaks the variables (
since some objects of the "base" variable end up in a secondary part). Sometimes models that have the same material are also combined and when some objects overlap (for example a panel with a grid variant) one of the parts is directly eliminated.
I have tried different versions of both blender and the conversion tools and blender tools, duplicating objects, assigning different materials, eliminating the "shadow" flavors that were assigned, applying modifiers manually before exporting and exporting from intermediate files (the pmg that are exported since the blender have the parts and variables correctly assigned, the problem occurs in the conversion from pim/pit to final game format), but the problem always repeats itself (although it almost never repeats itself in the same way, sometimes a model is assigned to the part "A", sometimes the same object appears in part "B")
The problem is the same as what is mentioned in this thread, but I don't understand the solution that is mentioned -> "Problem solved. Reason - own shadow model with "onlyshadow" mat. I delete it, and assign "shadow" in other pieces mats"

The versions that I usually use are Blender 3.1.2, Blender tools 2.3 and conversion tools 2.13, although I tried different more recent versions and the problem persists.

Thanks in advance,
Greetings

Did you ever find the problem? I’ve had this issue on and off and the only way I’ve fixed it is renaming the variant and part names over and over till it worked. It’s ridiculous..
