AI SKILL lumberyard

Lumberyard Documentation Reference

Faithful, task-routed reference for AWS Lumberyard and the CryEngine-family tooling it derives from, rendered from the full documentation corpus into one focused file per subject. Original prose; identifiers are preserved verbatim. This package routes to six area sub-skills — open the one that matches and use its references/INDEX.md. Lumberyard is archived (succeeded by Open 3D Engine); treat it as a historical reference.

When to use this

Use this skill whenever a task depends on Lumberyard or CryEngine-family behavior — the editor and asset pipeline, Cloud Canvas/AWS gems, Lua; entities/components/EBus/slices/prefabs; CGA/CAF/ CHRPARAMS/Geppetto animation; materials/MTL/shaders/decals/stencils; VFX/particles/rendering; or Wwise/ATL audio. It applies even when "Lumberyard" is not named but a relevant tool, file format (.mtl, .cga, .caf, .chrparams), or component is in play.

Do not use for Open 3D Engine (O3DE)-specific behavior, other engines (Unreal, Unity, Godot), or non-Lumberyard AWS work — those belong to another skill or a generic answer.

Workflow

1. Identify the area above and open that sub-skill's SKILL.md (or its references/INDEX.md).
2. Pick the one reference file that matches; read only what you need.
3. Treat every component name, EBus call, parameter, file format, enum value, and number as an exact reference fact.

Gotchas

Recurring failure modes and what to do instead live in the sibling GOTCHA.md.

References

Each sub-skill carries its own references/INDEX.md, references/topics.json, and per-subject references/*.md. Start from the area's INDEX.md.
