• Tiny textures: A novelty feature that scales textures down to a very small size. This has no use unless you intend for your import to rely on a texture pack.
• Link hierarchy: Link's skeleton uses a slightly different format than enemies and NPCs, so you must enable this option if you're converting a custom Link. Animations are also omitted.
• C output: The locations of models, animations, skeletons, and assembly textures will be printed using #defines, making for easier integration into custom actors.
• Play-as data: Embeds information meant to be processed by zzplayas within the resulting .zobj. Ideal for automated Link replacements, but unnecessary otherwise.
• Fix UV overflows: Fixes weird stretchy textures caused by SketchUp.
• Use MTL colors: Uses primitive color defined in settings for each material. Unused in most cases.
  
• Scale: The value by which to increase the size of the geometry and skeletal data. For models made in Blender, this is usually a value of at least 1000.
• Base Offset: All offsets in the file will be written relative to the offset given instead of the default 0. Additionally, if you specify a ram segment in the base offset (ex. 0x04005000), that will be used instead of the default 06.
  

Texture Naming Conventions

Warning/Error Codes

Mesh Naming Conventions

    riggedmesh    Only one of these may exist inside a rigged object.
                  This determines which geometry will be the main body
                  of the object

    ZZLMTX        Force limb matrix reference at start of DL;
                  required for Gauntlets, Iron/Hover Boots, and masks

    ZZBMTX        Force billboarding along all axes;
                  required for Hookshot Aiming Reticle

Material Naming Conventions

    ZZENV         Modulate "environment" color to texture. Use this for
                  Link's tunic, gauntlets, and the bottle

    TEXGEN        Enable texgen on a material
   
    NOCULL        Disable culling on a material

    ZZNOAA        Disable anti-aliasing (visible only on hardware)

    ZZDECAL       Use decal texture property


Assembly-Controlled Textures

    Link/NPC eyes and mouths are assembly-controlled textures that
    change in real time. To set geometry to use these properties, map
    a single eye or mouth texture to it. In this example, eyes.png.
    Then, in the same folder as eyes.png, create a texture named
    eyes_ZZBANK0x08000000.png. Replace 0x08000000 with whatever RAM
    segment is intended to be used to store the actual texture pointer.

Collision

Group names ending in _COLLISION are treated as collision. In such a group, the properties of the many triangles within are based on the names of the materials to which they are assigned. Color-coding each material will make it easier for you to tell which triangles behave in which ways. You can use multiple settings in the material name to apply multiple collision flags, just separate them with any of the following characters: .,|#:;

For example, a climbable metal grate that you can fire arrows through would be named something like this: IGNORE_AMMO#SOUND_CERAMIC#WALL_VINES

Here are all the options:
