Just chiming in to wish you good luck with this - we haven’t had an accessible 3D project for the Star Wars Saga on here before - so this should be cool to see when completed.

All the best with it. 👍

Edit…

Neptune’s Star Wars Saga 3D Conversion Project. (a 2013 thread; password protected files - passwords are unknown…)

and

murdav’s Star Wars: A New Hope (1997SE) - Download the Fan-Made 3D Conversion in 2160p HFR (Released) (ANH only)

^ are the only Star Wars 3D projects on here, IIRC. There is a ‘3D category’ in An Index for Star Wars Preservation (and scroll down)
