Create 2.5D scenes from any 2D background. Build environments inspired by classic titles such as The Longest Journey, Broken Sword, Syberia, and many more iconic 2.5D games.If you work with pre-rendered backgrounds, 2.5D Toolkit simplifies the entire process of turning them into interactive 2.5D scenes, helping you save production time.It merges 2D backgrounds, sprites and 3D objects to build scenes in the style of classic 2.5D adventure games.Built specifically for 2.5D development, it lets you transform any background image into a playable 3D scene in minutes. Supports both perspective and orthographic cameras.Set your PPU once. All imported sprites automatically inherit it.Camera size and distance are automatically adjusted, so sprites cut from your background need no manual scaling.Work almost entirely in the Game View for a fast, intuitive scene-building workflow.A complete toolset speeds up all the technical steps required to build a 2.5D scene, giving you more time to focus on gameplay and narrative.2Dto3D feature: Automatically generate 3D environments from a background image by providing just a few parameters.The system analyzes the image, estimates camera settings, and proposes valid configurations across FOV values from 5 to 60.This lets you select lower-FOV configurations that avoid distortion while preserving correct proportions.Export results as:Clean scenes - includes ready-to-use Main Camera and Background Camera prefabs.2.5D Toolkit data files - generates a data file to quickly rebuild the environment inside 2.5D Toolkit.Video: 2.5D Toolkit: 3D environment from 2D backgroundOnline manualSprite Editor feature: Crop simple or complex sprites directly from your background image.Draw precise shapes with support for internal transparent regions, letting you extract even highly detailed sprites.Customizable cursor styles help with precision cutting.Save sprites as standard or big sprites, each with its own PPU and pivot. Big sprites share the background’s boundaries for perfect placement.Video: 2.5D Toolkit: SpriteEditor (v3.5.0)Video: A way to place sprite with just a click in one secondBackground Editor feature: Crop or resize your background image to any size.Adjust the frame manually or enter exact values. Preserve original proportions or distort them if needed.Video: 2.5D Toolkit: BackgroundEditor (v3.6.0)Draw areas feature: Draw walkable and non-walkable areas directly in the Game View. Add unlimited regions, nest non-walkables inside walkables, and switch freely between Game View and Scene View.Non-walkable areas automatically block character movement - no colliders needed.Areas can be baked or exported as meshes, individually or merged.Online manual - MeshMultilevel feature: Build multilevel environments in perspective projection without physical geometry. Levels can remain separate (for jumping mechanics) or be connected with slopes, enabling complex layouts and convincing depth effects comparable to full 3D scenes.Video: 2 5D Toolkit: Multilevel Scene FeatureStaircase feature: Turn any suitable sloped area into a staircase. Set the number of steps and the toolkit generates the entire structure.Video: 2.5D Toolkit: Create staircasesOnline manual - StaircasesCharacter resizing feature: Automatic character scaling for both camera modes.In Orthographic Projection: define the size in the Character Resizing utility, and the script interpolates scale dynamically.In Perspective Projection: a dedicated depth-scaling system ensures consistent visual proportions even when camera settings don’t naturally provide them.Video: 2.5D Toolkit: How to Use Depth Scaling (Perspective mode)Path Finder script: Converts any click into the closest reachable NavMesh point. No setup required. Works in both orthographic and perspective modes, even in complex multi-level scenes.Video: 2.5D Toolkit: Path SearchingHorizontal Scrolling feature: Built-in horizontal scrolling for both projection types. Use long background sprites instead of a Background Camera. The camera follows the character smoothly and automatically detects scene limits.Define a neutral zone, customize scroll speed, and adjust camera-centering behavior.Video: 2.5D Toolkit: Built-In Horizontal scrolling (Perspective)Video: 2.5D Toolkit: Built-In Horizontal scrolling (Orthographic)Scene Import Utility: Import any previously exported 2.5D Toolkit scene with a single click.Cameras, objects, settings and optional characters are automatically restored.Video: 2.5D Toolkit: Scene Import UtilityVideo: 2.5D Toolkit: Import Tool for Adventure Creator - Background CameraVideo: 2.5D Toolkit: Import Tool for Adventure Creator - Horizontal scrolling---Build scenes directly in the Game View and place objects exactly where players will see them.What You See is What You Get.Export complete scene data to start a new project or create prefabs of all objects for an immediate, ready-to-use setup.During export, management scripts are automatically added, making the scene self-contained and compatible with any project or third-party system.Video: Recreating a short Broken Sword scene with Adventure CreatorCompatibility & NotesYou can Build and Run the scene directly from the editor to preview the result.Supports both the legacy and the new Unity Navigation systems.It can be used to generate freehand meshes or recreate them by tracing a background image, and is suitable for building environments for RPGs as well.This asset uses Poly2Tri under BSD License (3-clause BSD); see Third-Party Notices.txt file in package for details.Important:This is not an adventure framework. It is a scene-building toolkit that produces ready-to-use 2.5D environments. After export, only the character movement script and core settings remain; everything else is standalone.Tested on Windows.For Unity versions starting from 2022.2, make sure to install the Unity Navigation AI package first.As always, updates for 2.5D Toolkit owners are free.Online manualWebsiteFacebookYouTubeTested on Windows. Unity 2022.2+ requires the Navigation AI package. Import the Toolkit into a 3D Built-in RP project; after setup, you may use any render pipeline by adjusting materials.If you need help, clarification or new features, feel free to contact us.
