Nope, won’t hurt it. The project folders don’t know about each other and all the data in them is separate except for compiled shaders. I have the same project on different drives - one on 4.26 and the other on 4.27 compiled from source for plugin development.
iTween : Free, smooth, procedural object animation
easyCSV : Read data from any CSV and put them in an easy-to-access string map!
Runtime DataTable : Import and export game data to and from CSV or Google Sheets while your game is running!
