Are there still tools that do this automatically? I feel like there used to be quite a few in the early days of LDraw, but they are no longer actively developed/supported. Or maybe there were only tools to do it on your local library copy, not downloading?
If you open a model that uses a missing unofficial part using LDView, by default it will download the part and all missing dependencies into the Unofficial directory inside your LDraw directory. If you need to copy specific files, you could clear the Unofficial directory, then open the model in question, then copy all of the files in Unofficial to wherever is needed for stud.io.
