dayz-pack-texture

name	dayz-pack-texture
description	Convert PNG/TGA images to DayZ-format `.paa` textures via DayZ Tools' ImageToPAA.exe. Validates the required suffix (`_co`, `_nohq`, `_smdi`) on each input filename so the engine assigns the correct texture role. One-to-one: every input produces a `.paa` next to itself.

Path note: <skill-dir> in commands below is the absolute path of this skill's folder. When the agent loads this skill the harness exposes the skill's base directory; substitute it before running. Sibling skills are reached via <skill-dir>\..\dayz-X\.

/dayz-pack-texture

Convert one or more PNG/TGA images to .paa (DayZ's texture format) using DayZ Tools' ImageToPAA.exe. Each input file is required to follow the DayZ suffix convention so the engine knows what kind of texture it is:

Suffix	Meaning
_co	Color / diffuse
_nohq	Normal map
_smdi	Specular / mask

A file like vest_camo_co.png becomes vest_camo_co.paa next to it.

Follow .claude/skills/_shared/dayz-conventions.md.

How to run

python "<skill-dir>\pack_texture.py" <input1> [<input2> ...]

Argument	Required?	Notes
<input>	yes (one or more)	Path to a .png or .tga file with a valid suffix in the basename. Globs work via your shell.

What it does

1. Preflight gate.
2. Resolve ImageToPAA.exe from DayZ Tools (env / registry / Steam paths) via find_dayz_tools().
3. For each input:
   • Validate extension is .png or .tga.
   • Validate basename ends with one of _co, _nohq, _smdi (before the extension).
   • Invoke ImageToPAA.exe <input> <output.paa>. Streams the tool's output live.
4. Report a summary of successes and failures. Exit non-zero if any failed.

Refuses to run if

• /dayz-preflight returns non-zero.
• ImageToPAA.exe is not found under DayZ Tools.
• An input file doesn't exist.
• An input doesn't end in .png or .tga.
• An input's basename doesn't end with a recognized DayZ suffix (_co / _nohq / _smdi). The engine relies on the suffix to assign the texture role; without it the texture won't apply correctly.

Output

DayZ preflight
... (preflight output)
Preflight complete.

[OK]    ImageToPAA: C:\...\DayZ Tools\Bin\ImageToPAA\ImageToPAA.exe

[Pack] vest_camo_co.png  ->  vest_camo_co.paa
... (ImageToPAA output) ...
[OK]    Wrote vest_camo_co.paa (123,456 bytes)

[Pack] vest_camo_nohq.png  ->  vest_camo_nohq.paa
... (ImageToPAA output) ...
[OK]    Wrote vest_camo_nohq.paa (98,765 bytes)

[OK]    2 of 2 textures packed.

Do not

• Don't accept inputs without a recognized suffix. Silently producing a wrongly-named .paa masks an engine-side bug that's painful to diagnose later.
• Don't auto-rename inputs. If the user has vest_camo.png (no suffix), they need to rename it themselves so they're explicit about what role it plays.
• Don't re-implement DayZ Tools path discovery — import find_dayz_tools from dayz-preflight/preflight.py.
