For Diablo II: Resurrected, that contains the base game and Diablo 2 Items the Lords of Destruction expansion, 1 way to think about it's in that rotoscope or tracing sense. Employing the inherent assets and match as a way to drive the 3D layer. On top of taking each and every part and recreating it, animating it, including textures, and light too -- that the challenge mostly derives from the nature of moving 3D.
"It's the 2D into 3D world translation," Rod Fergusson, Executive Producer on Diablo II: Resurrected adds. "When you have a sprite-based 2D world it's a flat thing on a flat thing. And now you have stairs with elevation, you have undulating ground a sword must fall onto. Even simple things like readability turned into a challenge, such as a Paladin's Aura. The way that you're able to see the Aura very definitely lets you know you have that specific Aura. What if you're walking through a grassy area as well as the aura has been blocked by grass because that is 3D today and it's physically on the ground and growing up through the Aura. And there is clarity in Diablo II's 2D world"
"The backdrop could be fancy cushions, it may be heaps of skulls, it might be sand dunes, but it's really only a flat image," Rob Gallerani explains. "When you fall a sword, that's a 2D sprite. It is only a horizontal sprite and it sits on the top and you'll see it. When we have a 3D sword resting on 3D skulls and bumpy things, we can not just have it be there because it would clip all those items. So we must make sure it renders on a pass that's in addition to these items. There's a lot of loose ends that need to be accounted for when you're bringing a 2D sprite to a 3D world."
And it's that aspect, acquiring the 2D world drive the 3D layer that ensures the team preserves the game as is. Even with incorporating an impressive visual makeover, control support, along with a modern widescreen presentation that Cheap Diablo 2 Resurrected Items supports 4K TVs and ultrawide PC tracks, it's the same Diablo II that it has always been.
