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.
