Source data files are the files found in your editing kit's data folder. These are the assets which have not yet been converted into tag format by Tool (or Sapien in the case of scripts).

Types of data

Halo 1 makes use of the following source data formats:

• .JMS models which are imported as gbxmodel, scenario_structure_bsp and others.
• .WRL files which contain error geometry when the above fails. Note that the location and name of the generated WRL file depends on the Tool verb being used and the version of Tool (HEK vs H1A-EK). See the Tool page.
• .JMA, .JMM, etc files which are imported as model_animations.
• .tif textures which are imported as bitmap.
• .hsc scenario scripts, most commonly used to orchestrate singleplayer levels (e.g. AI encounters, cutscenes).
• .txt files imported as unicode_string_list.
• .hmt files imported as hud_message_text.

Instructions for importing these formats can be found on Tool's page. There are also community-made tools like Invader and Mozzarilla which cover some of these operations, and offer a different user experience or features.
