Do preloads nest with each deeper packed scene?

Help

I want to clarify how preloads work in nested packed scenes.

For example, if I have a script for a scene “Scene1” that preloads a packed scene “Scene2” , and Scene2’s script has its own preload to packed scene “Scene3”, does “Scene3” as a packed scene also get preloaded into memory when “Scene1” is parsed?

Probably, yes. Especially if you mean using preload in script (neither ResourcePreloader node), scripts parsed even if not used and preloads happens during parsing

Yes, the preload is only in the script. Thank you for your response.
