|Toontown 2.0 is not an actual subject, meaning it is not in the actual version of Toontown and/or was scrapped.|
The project best known as Toontown 2.0 (also referred to as Toontown 2) was a tech demo within Disney Interactive for a possible conversion of Disney's Toontown Online to the Unity engine. The development of Toontown 2.0 began sometime in or after 2010, but was canceled and its team dismantled by 2011.
The prototype made for Toontown 2.0 can be found to play here.
Disney's Toontown Online runs on the Panda3D game engine. While Panda3D (as an open-source game engine) remains in active development even after Toontown's closure, Disney had considered "remaking" Toontown in a new engine to have more versatility for things like multiple fluid animations.
David Rose, a software engineer at Walt Disney Imagineering, created a "basic version" of Toontown's functionality within Unity. Felipe Lara, a former art/creative director at Disney, was responsible for creating concept art in the general creative direction of what Toontown 2.0 could look like. His work included modeling levels and characters; notably, Toons were fully animated including mouths, eyelids, eyebrows, and more all being independently animated.
Unfortunately, Toontown's development team realized that it would require a lot of effort to recreate all of the resources from Toontown in the Unity engine. Disney was not looking to make such a massive investment into Toontown at that time, regardless of the efforts of its developers in trying to revive the project, resulting in the project being scrapped.
