Situation: I have a project with 20+ scenes and hundreds of text objects in random places (a song).
Is it possible to put the text object data (text itself) into a text file(s), to edit externally without the need of searching the object inside blender? So that edited and saved text file will update the objects in project on restart of blender?
PS: text objects aren't keyframed (if that makes a change).
This is an addon for writing text objects to .xml file and reading them back from the text file.
How to use:
install: from the addons tab click install from file and select this txt_xml.py file check the check-box to activate
UPDATE the addon file txt_xml.py
