Resident Evil HD Remaster is giving the classic game a new face with the aid of modern technology, but Capcom isn’t totally playing by the aging GameCube version’s rules. Graphics, lighting, and textures have evolved so much over the past decade or so that Capcom has gone back in and made a few modern adjustments to some of its set pieces.

In this developer diary, Producer Yoshiaki Hirabayashi explains that the development team has taken some liberties with certain rooms in the game. Most of the GameCube Resident Evil’s sets feature pre-rendered backgrounds, and these used repeating video files over them to breath some life and motion into the atmosphere.

Apparently, Hirabayashi wanted some of these rooms to use more modern lighting techniques, and that would have been impossible on the pre-rendered backgrounds. Instead, he and his team completely replaced the original backdrops with faithful recreations thanks to modern high-quality polygons. The effect still looks the same.

Hirabayashi also makes a point that this is done on a case-by-case basis as he didn’t want to stray too far from the game’s original resources. He claims that might have made it a little “soulless,” a sentiment I can get behind. It’s a very interesting way of recreating the game none-the-less, and I admire the loyalty to the source material as well.

Resident Evil HD Remaster will be released in early 2015 for the PlayStation 3, PlayStation 4, Xbox 360, Xbox One, and PC.
