A Ubisoft insider claims that the new Assassin’s Creed: Unity will fill every megabyte of data on a 50GB Bluray disc on the PS4. But what is filling the entire disc? On an episode of the Giant Bombcast (10/14/2014) at the 2 hour and 27 minute mark an insider writes in to talk about the game. Mentioning both the issues they had with the resolution and the frame rate of the game. He or she also comments on the issues they faced in order to get the game to the 900p with a locked frame rate of 30 frames per second.
But what fills up the disc? Turns out it was all due to baking in Global Illumination data.
So what does that mean? Global illumination is the addition of light to a 3D scene that is then bounced of many surfaces to produce a more realistic look. This light can pick up colour from surfaces it hits and reflect them onto adjacent surface, again producing a more realistic look.
Baking in these effects is a term used for re-rendering out the textures with the global illumination data onto them which drastically reduces rendering and CPU times. Resulting in a much fast experience. However, these files can be very large and could add a lot of data to game.
Assassin’s Creed: Unity is coming out November 11th 2014 and we can’t wait to see how it is going to define this generation with its AI and visuals.
