Body Explainer 3D skill

Make vertical "what happens inside your body" 3D explainers (warm skin, cutaway window, macro camera dive) with the SceneSkills Body Explainer 3D kit.

Short vertical explainers about the body in real 3D: a bright blue-sky studio, warm physical skin, and a macro camera that dives in through a growing cutaway window to show bone, cartilage and fluid doing their thing. Demo: Why Knuckles Crack (film.js).

What the skill teaches your agent about the style:

World: soft gradient blue sky, sun key light, sky fill and a rim light. Skin is physical (pores, soft subsurface light), never plastic.

The move that defines the kit: start outside on the body part, then dive in through a cutaway window whose ragged pink rim grows open. Inside parts (bone, cartilage, fluid, vessels) only show through that window.

Camera: always moving: dive, pull back, orbit a little. Small shake only on real impacts (the pop).

Text: short centred captions (2-4 words), clean labels with leader lines for anatomy ("SYNOVIAL FLUID"), a big number or timer when the script gives one.

Pacing: 30-50 s, a hook question in the first line, the answer in the middle, a myth check or surprising fact at the end.

1. 1

   Plan the film

   Topic + script (shape above) + the body part and the inside parts needed. Show it.

2. 2

   Build the body part

   If the part is not a hand, build the outside mesh (MakeHuman part via tools/build_hand.py as a model) and the inside parts with MAT materials.

3. 3

   Voice and timing

   Voice -> voice_prep.py -> copy timeline.py, name cues on the words.

4. 4

   Check stills

   Copy film.js; keep the sky world, skin and window; swap the anatomy; drive the dive with cameraRig keys on the cues.

5. 5

   Check stills

   Stills at 270x480 (two or three rounds), render 1080x1920 (heavy: allow ~3-4 s per frame on a laptop CPU).

6. 6

   Sound and mix

   Sound from soundmap.json + body sounds; music ducked; -14 LUFS.
