3D Explainer Video
Cinematic low-poly 3D worlds with sweeping cameras and built-in subtitles. Explain an idea as a small animated film — no 3D software needed.
About 3D Explainer
Low-poly cinematic explainer films, the flat-shaded-animation way: simple geometric worlds under warm gradient skies, slow dollies and hard cuts, and burned-in serif subtitles on a full 16:9 frame (letterbox bars are opt-in). You describe the film; your AI agent builds it, and the 3D engine plays it back in perfect sync with the timeline.
What your AI agent can build here
The template seeds the 3d-explainer skill, so any AI agent working in a project made from it already knows the whole format:
- Scenes & cameras — a scene list with absolute start/end times, one eased camera move per shot (push, drift, orbit, or a held frame), and hard cuts between scenes. The skill encodes the genre's camera language: low eye-level framing, one slow move per shot, centered key beats, layered foreground depth.
- Light & weather — per-scene gradient skies, sun/ambient rigs and fog, with optional in-scene drift (dusk deepening into night) or a hard lighting snap at a cut.
- A props catalog — ground with hills, trees, rocks, clouds, star fields, stylized characters, coins, tables, glowing beams, floating 3D text, free-form composite shapes, and seeded scatter that snaps to the terrain.
- Rigged 3D characters — bring in ready-made 3D characters and play their moves in sync with the film, or have your agent choreograph motion pose by pose — walks, flips and cartwheels included.
- Narration sync — the standard voice loop: write one paragraph per beat, render TTS parts with the audio plugin, place them on the timeline, then retime scenes and subtitles to the actual voice durations.
- Subtitles & finish — word-proportional subtitle beats per narration part, vignette, and optional cinematic bars, all burned into every exported frame.
How to work with it
- Use this template and give the project a name.
- In the project window, ask your agent for the film you want — "a 90-second low-poly explainer about quantum superposition, dusk mood, one coin as the hero prop".
- Scrub the stage while your agent works; the preview catches up within a beat.
- Add narration when the visuals settle, then export.
The bundled samples are finished films made exactly this way — open one as a project to see a finished film, its narration and its timeline wired together.
