What are CROCOTILE files and how to open them

Are you having problems opening a CROCOTILE file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your CROCOTILE files.

What is a CROCOTILE file?

A .CROCOTILE file is a Crocotile 3d Project file.

A project file records a complete 3D scene created with Crocotile 3D, a tile-based environment editor. These files store the arrangement of tiles, textures, camera settings, lighting, layers, objects, and other scene data so that a scene can be saved and reloaded in full. Scenes are built by selecting tiles from images ("tilesets") and placing, transforming, animating and organizing them into objects or instances within a 3D grid.

Crocotile 3D is the program that writes and reads these scene files. The software allows designers to build 3D environments using 2D tile images, adjust UV mapping, set up lighting and shadows, animate UVs, configure cameras (perspective or orthographic), and group elements into objects or prefabs for reuse. When the user saves work, the project file captures all these settings so that reopening the file restores the full scene.

These files use JSON format for storage. Their content begins with an ASCII object containing a "config" section with tilesize parameters, and various fields like camera type (e.g. PERSPECTIVECAMERA or ORTHOGRAPHIC), scene objects, prefabs, texture/image settings, UV padding data, vertices, names, positions, enabled flags, and other descriptive properties. Keywords include TILEPALETTE, OBJECT, PREFABS, CAMERA, SHOWSKYBOX, VERTICES, MODEL among many others.

A typical file will begin at offset zero with the ASCII characters '{"config":{"tilesizeX":', establishing the tilesize in X dimension (followed by tilesizeY and other settings).
