This page needs to be rewritten for Godot. This is no longer relevant as this only applied to the previous engine used by Thrive.
All importing of assets to Thrive can be done via the Godot editor. These are the file types currently used in Thrive (though other file types compatible with Blender Textures are generally .png files. Models are generally .glb files (which is necessary for animated models) or directly imported from Blender as .blend files. Icons can be either .png or .svg files.


First you need the import tool. You can download the latest release to get it (after 0.4.2 is released, for now you need a dev build). The import tool is LeviathanEditor.

== How to run the tool ==
There is currently no GUI for the importing. LeviathanEditor can be ran from the terminal or cmd.exe with the import flag. There is also a helper script included (AssetImportHelper.rb) if you have ruby installed (on Windows use [https://rubyinstaller.org/ Ruby installer]) you can just double click the script to run it (or in terminal / cmd.exe run "ruby AssetImportHelper.rb"). Note: the script needs the os gem to run (install with the command "gem install os", once you have ruby installed and added to PATH).
It will automatically create the source and target folders on first run. Then you can place your raw assets in the "raw assets" folder and run the script again. The processed assets will be placed in the "processed assets" folder.
 
If you prefer running it like a command line tool, it works like this: "LeviathanEditor --import source_folder target_folder" Replace source_folder and target_folder with the folders where the raw assets are and where the assets should be placed. For example you can create two folders next to LeviathanEditor called "raw" and "assets", and use a command like "LeviathanEditor --import raw assets". Be careful with spaces in the filenames as you need to put quotes around the path if there are spaces.
 
 
Once imported you can rename the .asset file and move it into the Thrive Data folder to have the game detect the file. You can replace an existing file to have your asset version replace it.
 
== Asset requirements ==
The type of asset to import is detected based on the extension:
* Image files should be .png files (and a multiple of 4 in size)
* Models need to be .fbx files (blender has a default exporter for fbx)
 
== Options files ==
The importing of assets can be tweaked by including options json files. For example the image compression and animation importing can be set using these files.

Updated for Thrive 0.7.0

All importing of assets to Thrive can be done via the Godot editor. These are the file types currently used in Thrive (though other file types compatible with Blender Textures are generally .png files. Models are generally .glb files (which is necessary for animated models) or directly imported from Blender as .blend files. Icons can be either .png or .svg files.

Additionally if you are making a modified version of an asset you'll want to get the raw version of the asset. You can clone the whole of Thrive from GitHub, which gives you all the assets as they are used in the game. Note that you need Git and Git LFS to clone it properly. Some assets that don't need to be converted are stored in the main repo, but also use Git LFS. The raw versions are also stored here.

These instructions are for modellers. For programmers there are no Godot technical guide by us yet, so look up Godot 4 tutorials.

Requirements for Models

There is an outdated page that has some general instructions for how to make models that are suitable for importing: blender-and-ogre-tutorial

Here's a short list:

  • In most cases, the model should be placed at 0,0,0.
  • It's generally best to center the mesh on its origin. In Blender, activate the Snap pie menu (default Shift-S) and select 'Cursor to Origin', go into Edit mode, select all vertices, activate Snap pie menu (Shift-S) again and select 'Selection to Cursor (Keep Offset)'.
  • It's best to apply all transforms (translation, scale and rotation) on the model before importing into Godot.
  • The model can be translated, rotated or scaled in Godot if needed, though in some cases this can add complications.
  • Armatures should have named animation tracks.
  • Vertex counts for models should be reasonable compared to how much screen space the model takes up.
