Zombies

ACT3 AI supports zombie characters as fully controllable digital actors. From slow shambling hordes to fast aggressive runners, fresh-turned victims to centuries-old undead, every variation is achievable through the appearance and performance description system.

Zombie Digital Actors​

Zombies are created like any other digital actor — describe their appearance and the AI renders them accordingly. You control the degree of decay, the emotional affect, and how human they still appear.

Creating a zombie character:

  1. Open the Actor Library and click New Actor
  2. Describe the zombie's appearance and decay level:
    • "Recently turned — pale skin, bloodshot eyes, torn office clothing, confused disoriented movement"
    • "Advanced decay — mottled grey-green skin, sunken eyes, exposed jaw on one side, slow dragging gait"
    • "Fresh military zombie — still in fatigues, one arm missing, aggressive forward-leaning posture"
    • "Elegant Victorian undead — formal dress, grey pallor, blackened fingertips, eerie stillness"
  3. Set the performance style: Shambling (slow, lumbering), Aggressive (fast, lunging), Still (standing waiting), or Coordinated (intelligent zombie variant)
  4. Assign voice — zombies can be silent, produce moans and grunts via TTS, or for intelligent undead characters, speak full dialogue

Half-Human Zombie Variants​

ACT3 AI supports hybrid zombie characters that blend human and undead traits — useful for:

  • Early-stage infection — mostly human appearance with creeping decay starting at the edges, red veins in the eyes, pale lips
  • Intelligent zombies — retain human speech, clothing, and reasoning but with undead visual markers; can carry full dialogue scenes
  • Partial transformation — one arm or side transformed while the rest remains human; useful for horror drama about characters mid-turn
  • Supernatural undead — mix zombie decay with other supernatural elements (glowing eyes, shadow effects, spectral translucency)

Intelligent zombie characters can be fully realized speaking characters who deliver dialogue, express emotion, and carry scenes as protagonists.

Zombie Hordes​

For crowd scenes, place multiple zombie actors in the same shot using the Top-Down View in the Editor:

  1. Open Top-Down View in the editor workspace
  2. Drag multiple zombie actor icons onto the set
  3. Assign different zombie presets to each for visual variety (varied decay levels, different torn clothing)
  4. Set movement paths for each character — converging on a location, wandering in patterns, or standing in a crowd
  5. Use staggered movement timing to avoid uniformity in the horde

Zombie Sets and Environments​

Use the Sets system for horror environments:

  • Post-apocalyptic street — abandoned cars, broken windows, overgrown pavement, scattered debris, fallen signage
  • Hospital interior — overturned gurneys, flickering lights, bloodstained corridors, emergency lighting
  • Shopping mall after the fall — broken storefronts, debris, abandoned merchandise, skylights with vegetation growing in
  • Rural farmhouse — isolated, boarded windows, foggy fields, barn in the background
  • Underground bunker — claustrophobic, harsh utility lighting, reinforced doors, survivor supplies
  • Graveyard at night — fog, crumbling headstones, moonlight through dead trees, fresh earth turned over

Cinematography for Zombie Scenes​

Use these descriptors in your shot prompts for horror atmosphere:

  • "Handheld close-up of survivor's face, terror in the eyes, zombies out of focus in background, shallow depth of field"
  • "Low angle on zombie horde approaching down a dark street, streetlights casting long shadows, slow menacing advance"
  • "Extreme close-up of zombie face, dead eyes, skin detail, absolute stillness, then sudden violent movement"
  • "Wide shot of abandoned city street at dawn, lone figure in distance, zombies scattered throughout, eerie quiet"
  • "Dutch angle inside dark building, flashlight revealing zombies around a corner, high contrast shadows"

Lighting for Horror​

Lighting is critical in zombie productions. Key techniques:

  • High contrast / Noir preset — deep shadows, defined single key light, maximum tension
  • Practical lights only — flashlights, emergency lighting, fires — creates authentic post-apocalyptic atmosphere
  • Cool blue ambient with warm isolated practicals — the classic horror contrast (cold world, small human warmth)
  • Night Exterior preset — low ambient, artificial sources casting isolated pools of light
  • Flickering lights — use the flicker control on practical lights for hospitals, tunnels, and power-failing environments

Zombie Costumes​

In Costume Design, create torn, bloodstained, and decayed wardrobe variants:

  • Start with normal clothing (work uniform, casual wear, formal attire) as the base
  • Layer in damage: "shirt torn at the shoulder, blood-stained collar, missing one shoe"
  • Different professions make visually distinct zombies — hospital staff, police, business suits, construction workers
  • Use scene-specific variants for a recently-turned character who becomes progressively more decayed across scenes

Tips for Zombie Productions​

  • Vary your zombie population — diverse appearance, clothing, decay level, and movement style make crowds feel real rather than copy-pasted
  • Build emotional contrast: show who the zombies were before they turned; survivors reacting to recognizing someone they knew
  • Use the Story Arc system to track survivor group dynamics, resource depletion, and moral choices as beats
  • For intelligent-zombie storylines, treat the zombie protagonist exactly like a human character in the story structure
