Making Library Nodes: Notes

Ideas

Don't just randomly make models—make sure there's a need for them. First check the Needed Objects page, and discuss with the team to clarify what they need. Concept art is also extremely helpful, but don't spend too much time on it.

Importing Models from other sources

If Blender can import it, the SuperTuxKart exporter scripts can export it. If you prefer to create your models in another program, you can simply import them into Blender (provided the format is supported) by going to File > Import in Blender's info window. However, you will still need to set up materials and other properties to be able to use your models in SuperTuxKart.

Blender

Blender can be difficult to learn. However, start with a basic object and learn from there. Making objects for SuperTuxKart is a great way to help while learning Blender, and a great way to move toward more advanced things like making tracks or arenas.

Library Node IDs

Every library node must have an ID. The format is

The object name should be short and descriptive. It should not explain the details of your object, such as a plant's species. If an object similar to yours already exists in the library folder of the media repository, use a different variation letter. Suppose you would like a palm tree in a track, but you don't like the kind already in the media repository. You would notice that stklib_palmTree_a already exists. Therefore you would use stklib_palmTree_b for your palm tree model's ID.

File Locations and Naming

It is extremely important to have consistent naming for library nodes, since other artists will be using them.

  • The .blend file should be named with the library node ID with the .blend file extension.
  • The object to be linked in a scene (of type Object, LOD Instance, or LOD Standalone in the SuperTuxKart Object Properties panel) should be named with the library node prefix suffixed with _main. For example,
  • Other objects (e.g. LOD Models, particle emitters, etc. should be given a clear and identifying name to avoid confusion.)
  • To prevent errors in texture linking, you should have a directory structure like this: (Some folders are excluded for conciseness.)
