▸ THE LINEAGE OF AN IMAGE · HYBRID 3D × AI

Provenance

Every finished frame carries a history. A hand-drawn sketch becomes a photoreal image under custom diffusion; that image is converted to editable 3D; the 3D structure widens the shape language and feeds new variants back up the chain. The path broadens while the look refines.

These are real assets from the Gothic Mechanica corpus, traced across the workflow stages. Some chains are complete; others are placeholders we will fill as the pipeline runs — marked accordingly. New here? Start with The Method for the full story, or dive into a domain below.

S3 · sculpt Untextured ZBrush sculpt of a tiered citadel, red symmetry guide curves on the geometry

S4 · generative ↓ Photoreal generative gothic citadel district at night with a hovering ship and searchlights

Citadel · sculpt → photoreal same shape language, two stages

S1 · Hand-drawn → S2 · Reference photo → S3 · 3D sculpt / render → S4 · Generative image → S5 · 3D-generative structure

The chain is non-linear: a generative image can be converted to 3D, and a 3D structure can be re-rendered back into a new generative image. The stages describe medium, not strict order.

FIG. PR-00 · THE LOOP

Sketch in, three modalities out

HAND → AI SHADE → IMAGE→3D → MASTER SCENE → ZB · MAYA · UE5

Lineage flow: hand sketch to AI shade 2D to image-to-3D (NeRF/GS) to master scene, branching to physical 3D, 3D rendered, and generative 3D

From the Hybrid-3D LDM whitepaper. The hand sketch shades into a 2D image, converts to a 3D master scene, and that scene populates the three output modalities. ZBrush, Maya, Substance, and Unreal carry the asset from sculpt to staged plate.

★ HERO CHAIN · SAME SUBJECT, EVERY STAGE

The ceremonial figure

SCULPTED → RENDERED → GENERATED

One character, traced end-to-end. Sculpted in ZBrush, exported as a clean clay render, then realized photoreal under the custom diffusion model — the same horned headpiece, the same shoulder-creature pauldron, the same profile, at every step.

S3 · ZBrush → ZBrush viewport — the ceremonial figure sculpt in progress

S3 · clay render → Clean ZBrush clay render of the ceremonial figure, profile

S4 · generative Photoreal generative realization of the same ceremonial figure

Ceremonial figure · the seam-keeper ZBrush sculpt → clay export → custom-LDM photoreal · same pose / headdress / pauldron

PLACEHOLDERS · TO BE REFINED INTO FULL CHAINS

Reading a chain

Each row is one subject caught at two or more points along its life. Read left to right as the medium hardens — graphite, then clay, then a generative frame, then editable geometry. What you are watching for is persistence: the silhouette that survives the jump from one tool to the next. When a hull stencil, a horn, or a visor reappears unchanged three cells over, the lineage is no longer a claim — it is evidence.

S1 · hand-drawn → Hand-drawn grayscale sketch of the seawall dry-dock gate with a single red accent

S4 · generative Photoreal generative dry-dock canal with hovering freighter

Seawall gate · Coalition dry-dock hand sketch (red accent) → generative photoreal environment

S1 · the hand-drawn anchor

Most chains in this corpus begin in 3D; a true hand-drawn origin is rare, which makes this one worth pausing on. The single red accent in the graphite is not decoration — it is the red rule of Gothic Mechanica carried in from the very first stroke: red lives only on a body, never in the architecture or the air. The generative frame obeys the same law it was born under.

S3 · sculpt → Untextured ZBrush sculpt of a citadel tower

S4 · generative Photoreal generative citadel tower over a night city

Subterranean citadel · spire 3D sculpt → generative photoreal environment

Sculpt first, so the diffusion has something to obey

The citadels are built before they are photographed. A rough ZBrush mass — proportion, tier-count, the lean of the spire — is locked in geometry first; only then does the diffusion model dress it in fog, torchlight and weather. The sculpt is the leash. It is why two generative plates of the same tower read as the same place under different skies, instead of two unrelated images that merely rhyme.

S3 · ZBrush sculpt → Matcap ZBrush sculpt of the recon pilot head, profile

S4 · generative Photoreal generative full-body recon pilot, amber-visor helmet and breathing mask, in the dry-dock fog

Recon pilot · Coalition ZBrush sculpt → custom-LDM photoreal · the same helmet, visor and breathing rig

A face holds across the jump

The pilot is sculpted in ZBrush first — helmet, wraparound visor, the breathing rig — then realized photoreal under the diffusion model. A face is the hardest thing to keep consistent and the first thing an audience interrogates; that the same kit survives from grey clay to a lit frame in the dry-dock is the whole proof in miniature.

S4 · generative ▸ clean 3D twin · pending upload Photoreal generative Hydra-class creature with red dorsal spine, crouched on black sand

Hydra-class creature · generative photoreal plate · a clean 3D twin exists and will be uploaded to close the chain (and obeys the red rule — red only on the living spine)

S4 · generative Photoreal generative silver subterranean corridor, a vast symmetric riveted tunnel converging on a luminous sphere

Silver subterranean corridor · the deep machine a generative plate built for conversion — the kind of dense, coherent frame that becomes editable geometry downstream (a motion twin of this plate already exists)

What a plate is for

A frame like the corridor above is not the end of the road — it is raw material for the next stage. Its symmetry, depth and rivet-by-rivet density are exactly what an image-to-3D pass needs to recover believable geometry. Hold that thought against the clean structures below: the generative image is the quarry, and the 3D model is what we cut out of it.

S5 · 3D structure ▸ placeholder · pairs with a generative gate Clean untextured 3D spire structure

S5 · 3D structure ▸ placeholder · image-to-3D output Clean untextured 3D arch/gate structure

Generative structures · image → 3D clean geometry generated from a generative image (NeRF / Gaussian-splat / image-to-3D)

S5 · the loop closes

This is the rung that turns a one-way render into a cycle. A generative plate is lifted back into clean, editable geometry — NeRF, Gaussian-splat, image-to-3D — and re-enters the pipeline as a buildable asset that can be cut, kit-bashed and re-staged. The image was never the destination; it was the route back to the model. Follow any thread far enough and it returns to 3D, ready to start again.

▸ STATUS · EXAMPLES, NOT YET REFINED

These are working examples pulled from the corpus to prove the provenance story. The hero chain is real and complete. The other chains are representative placeholders — as the pipeline runs we will replace them with verified end-to-end captures (same subject, every stage, including the missing S2 reference-photo rung and the S5 image-to-3D conversions).

This page is standalone and pluggable — it can live on its own, embed into the Bridge, or anchor a section of the Demo. We refine here, then decide where it lands.
