During our work, we realized that we spent a lot of time preparing the environments for 2.5D worlds. Building the navigation mesh with third-party software cost much effort and often needed to start from scratch because the game required changes in the background. Placing objects in 3D space also took away a lot of time that we could use instead in the most important stages of game development. We had to speed up these phases of the process and we designed the 2.5D Toolkit for Unity.
