Content Packs

An open asset format — two modes, one manifest spec.

Prototype vs Presentation

The content-pack format defines two modes — pick the one that fits your stage of development. RakuAI ships the format, the manifest spec, and the validator; you bring or capture the assets that fill it.

Prototype versus Presentation: the same scene shown as muted wireframe placeholder shapes on the left and as polished gradient-filled glossy shapes on the right. PROTOTYPE solid colors · fast iteration PRESENTATION HD textures · VFX · adaptive audio

Prototype Mode

Lightweight placeholder assets designed for fast iteration. Simple shapes, solid colors, and basic sound effects so you can test gameplay logic without waiting for art. Ideal for game jams and early prototyping.

  • ✓ Minimal file sizes
  • ✓ Instant load times
  • ✓ Clear visual hierarchy
  • ✓ Consistent color coding

Presentation Mode

The profile for polished, high-fidelity work — the textures, models, particle effects, adaptive music, and UI you bring to the pack (or capture with Raku Capture) for demos, trailers, and showcases.

  • ✓ HD textures & sprites
  • ✓ Multi-layer adaptive audio
  • ✓ Particle VFX support
  • ✓ Themed UI components

Template Families

The content-pack format and genre manifests cover a wide range of game genres — each with a Prototype and a Presentation profile.

Action & Combat

Characters, environments, effects, and audio for fast-paced gameplay

Strategy & Logic

Maps, UI elements, and assets for strategic and puzzle-based games

Adventure & Exploration

Worlds, tilesets, and atmospheric audio for open-ended experiences

Custom

Flexible base assets for building any game genre

Integrated Audio

The content-pack format has structured audio slots — background music, sound effects, UI audio, and adaptive elements that respond to gameplay in real time — so audio plugs into the pack alongside everything else.

Build a Content Pack

The manifest spec, asset-integration guides, the pack validator, and complete documentation come with SDK access — everything you need to author a content pack and plug your assets in.
