Current questions and answers regarding the map editor.

Hmm, I was interested in this myself once, but all I could find was in the script for the 2nd mission of Wolfenstein from Lords, where it showed neutral mine/dwelling structures around a warrior's grave. The effect itself was activated through PlayVisualEffect, and the name of the effect was: "/Effects/_(Effect)/Buildings/Capture/_BuildingFree_S.xdb#xpointer(/Effect)". Maybe you can find specific models with colors and faction icons in the data folder at that address.

UPD: I just checked the data.pak archive and found folders with faction names at the address /Effects/_(Effect)/Buildings/Capture/. And in each one, there are subfolders with different color variations of the effects (from red to brown). So, there shouldn't be any difficulties in applying them to an object.

Thank you for sharing your experience :)
I will definitely test it.
I always want to say "I'll report the results," but I realized it's better to finish the map first so I can simply refer to the developed materials.
And another question, maybe you know (or someone else who is as smart and experienced): Are the descriptions and tooltips for objects unique to the player, or are they common for everyone? I'm creating a map that is bilingual in terms of text (there are reasons to write them in English as well),
but the descriptions of custom objects are not dynamic, in the sense that it's not just a text box, but a fully-fledged text that is always available to read. And it turns out that I only specify the English versions everywhere,
because if an English speaker understands Russian, the opposite is not true.
