Greenberg now works as the animation director at Infinity Ward and has fond memories of his time at Squaresoft.
"I was originally hired onto the project as a 3D artist," recalled Greenberg. "One of my main roles was supposed to be to help them with performance issues by reducing the polygon counts on many of the character and creature models." Luckily for the game, though less fortunate for Greenberg, the programmers were able to develop a PC renderer efficient enough to use the PS1's original models, without compromising on polygons. Instead of working as a 3D artist, Greenberg ended up doing touch-up work on the 2D art, increasing the resolution of assets from 320x240 to 640x480.
"Mostly I focused on all the fonts and menu icons, and any textures used in the UI. Doubling the resolution of the Final Fantasy finger icon was actually a pretty cool thing to work on. It's literally iconic. There were no fancy upres-ing algorithms to use back then so I was basically filling in a ton of pixels by hand. You could imagine it wasn't all that creatively challenging and not the best use of my skillset as a 3D artist."
Greenberg also worked on Final Fantasy 7's FMVs, which were compressed for the PC release rather than improved. "Unfortunately we didn't have access to any higher resolution renders and they wouldn't provide the original assets to re-render, so sadly I had compress most of the FMVs from the 320x240 versions.
Making them fit in the disc space required and playback properly was quite a challenge. In the end, I don't think they looked as good as they could have. If only Sqaure had been able to provide higher resolution frames. We had the same issue with many of the backgrounds. These were simply too dense to double resolution and touch up by hand so most of them I think were the direct PS1 versions."
In 1998, you couldn't do the kind of 3D graphics work that went into Final Fantasy 7 on a normal PC. Greenberg had a $30,000 Silicon Graphics workstation on his desk "with probably Ssoftimage and Nichimen Graphics software on it to do the low-poly modeling" he never ended up actually working on, but he did put the hardware to use once. As a big chocobo fan, he created a new Squaresoft logo cinematic for the PC version. That's one bit of Final Fantasy 7's history we can definitively put a name to.
