* This provides new 3D objects: 3D Box (perfect to create walls, floors, or billboards) and 3D Model (to import objects created in a 3D modeling app).
* 2D and 3D can be mixed in a same game. Each layer of a game can contain 2D objects, 3D objects or a mix of both.
* This allows to build 2D games, 2.5D games and full 3D games: platformers, racing games, FPS, hyper casual games. It's easy to start adding 3D objects to an existing 2D game.
* You can set up a light by adding an ambient light and/or directional light in the effects of a 3D layer. 3D objects can be configured to react to light or ignore it.
* In the future, support for 3D objects will be improved: light objects, animations, etc...
* This allows to generate interesting visual effects, which can be controlled by events. For example, you can use an outline on an object to highlight, make the player glow when launching a spell, blur objects, etc...
* A new "effects" tab is now present in the objects editor. From there, you can add visual effects, that were already available for layers, customize them from this editor.
* Actions and conditions are available to manipulate effects and change their parameters during the game.
