When you're done, you put the whole lot in a ZIP file and change the extension to. jsonfile, and also a subdirectory called images. In short, when creating a JSON object, you should first make a directory for the object. The Panda train is the only official object that does include sprites, so you can look there to see how it works. Most of the official objects simply reference base game assets, and don't actually include any sprites. I see there is some lines of code that reference an image of some kind but im not sure how that part works I myself have just started experimenting with it. Sadly, there's not much documentation but there's a lot of examples in the form of official objects, and you can always ask the OpenRCT2 developers if you get stuck. It's much more straightforward to work with than the original DAT format because it makes use of standard file formats (JSON, PNG, and ZIP) instead of a custom binary encoding that requires purpose built software to read and write. I do hope that one day due to open rct2 there will be a much easier way to add custom content. If not, the list of angles that you need to render are documented here but finding lighting/dithering parameters that work well may take some experimentation (OK, a lot of experimentation - I suggest looking at what he did and using that as a starting point). If you intend to use Blender for your modelling then I recommend Oli414's plugin - it will automatically render all the correct angles, peep sprites, and dither them down to the RCT2 palette. My recommendation is to start with creating the model for your trains. DAT files, JSON objects currently cannot be exported with saved games, so users must install the object manually. You can take a look at some of the official objects to get an idea of how the format works. However, you can use OpenRCT2's new JSON object format instead - since it's entirely text based, you only need a text editor to work with these files. DAT file from the sprites - the object editor doesn't support custom trains as far as I'm aware and Buggy's ridemaker has very limited capabilities (though you can work around this with hex editing if you know what you're doing) There really does not exist any decent software for creating a. There's a couple of downsides - it only works with Blender 2.79 (which is not the latest version), and it is only a renderer - it can't actually write to a. Oli414 has written a Blender plugin that automates the rendering of sprites for custom tracked rides. You will need 3D modelling software, firstly.
