models/ignifx-ship.glb — 3 057 368 bytes#

The ignifx mascot ship, and the default subject of pbr-model: one mesh, one metal material with base-colour, packed occlusion/roughness/metalness and normal maps, hovering over the studio floor.

ignifx mascot ship — © 2026 Astrum Forge Studios Pty Ltd. A brand asset supplied by the owner on 2026-09-07 (original: website/brand/source/spaceship.glb), used under the ignifx trademark rules on /press/; not a sample asset for reuse.

Hero only. pbr-model is the one example that may load it, and therefore the one poster and the social card that may show it. No other example, template or recipe loads models/ignifx-ship.glb.

Derived from that original, which is never modified. The source arrives meshopt-compressed and quantised at 1 942 544 triangles / 1 036 134 vertices with three 4096px JPEG textures; dequantised and uncompressed that is 59 462 228 bytes, so it cannot be shipped as it stands. The committed file is 67 983 triangles / 50 317 vertices — 3.5% of the original — with the normal map carrying the detail the collapsed edges gave up, and it renders at 12 draw calls. EXT_meshopt_compression and KHR_mesh_quantization are read at build time and not written: the meshopt runtime decoder would be a CDN fetch, which CONSTITUTION.md §9.1 forbids, and nothing in this repository has verified Lite against a quantised file.

models/corset.glb — 1 599 040 bytes#

A fabric mannequin wearing a corset with a printed pattern, brass eyelets and a leather trim: cloth, metal and fine normal detail in one small model. It was the hero until the owner supplied the ship, and it stays as the pbr-model panel's second subject, because swapping a loaded model at runtime is one assignment and that is worth showing. Compressed from the Khronos sample's 13 491 364 bytes with _tools/compress-model.ts — 11.9% of the original — by welding the geometry and re-encoding the textures (base colour to 1024px JPEG at quality 84, the normal and packed occlusion/roughness maps to 512px PNG).

models/lantern.glb — 851 508 bytes#

An old wooden street lamp: a post, a curved arm, an iron-banded base and a glass lantern hanging from a chain, in three meshes and one material. It is the subject model-loading opens on, because its silhouette still reads at the size the gallery draws a poster and its authored scale — 25.66 units tall — is the clearest possible demonstration that borrowed art does not arrive in metres. Compressed from the Khronos sample's 9 564 264 bytes with _tools/compress-model.ts — 8.9% of the original — by welding the geometry and re-encoding its four textures (base colour and emissive to 1024px JPEG at quality 84, the normal and packed occlusion/roughness maps to 512px PNG).

models/water-bottle.glb — 570 720 bytes#

A brushed-metal sports bottle with a printed label and a plastic cap: one mesh, one material, and the canonical metal-roughness test object. Compressed from the Khronos sample's 8 966 700 bytes with _tools/compress-model.ts — 6.4% of the original — by welding the geometry and re-encoding its four textures the same way as the lantern above.

models/fox.glb — 162 852 bytes#

A low-polygon fox on a 24-joint skeleton with three animation clips — Survey (3.42 s), Walk (0.71 s) and Run (1.16 s) — one mesh and one 1024px PNG texture. Two examples load this file: skinned-animation, which drives the clips directly through a two-state animator document, and animator, which drives the same three clips from a state machine with a trigger and an event.

Committed byte for byte as Khronos publishes it: at 162 852 bytes it is already a fortieth of the per-file cap, it declares no glTF extension at all, and _tools/compress-model.ts would run resample() over its animation channels for no gain. The digest below is therefore also the upstream digest, which is how the download was cross-checked.

Three parties hold rights in it and the model's own metadata.json lists all three; all three lines are required wherever it is shown:

• SHA-256: d97044e701822bac5a62696459b27d7b375aada5de8574ed4362edbba94771f7 (identical upstream: the file is unmodified)
• Bind-pose extent: 25.185 × 79.029 × 154.72 glTF units, its box centred at (0, 39.39, −10.735); skinned-animation/main.ts draws it at 0.01, which makes it a 0.79 m animal

models/rig.glb — 10 152 bytes#

The repository's own skinned "box-man": four joints (hips, torso, armL, armR), 32 vertices across four boxes, four clips (idle, walk, run, jump) and a geometry-free hand node for Model.attachToNode. third-person uses it as the thing the camera follows; the example itself is about ThirdPersonController and ThirdPersonCamera, not about the model, and a rig this small keeps it that way.

It is original work by Astrum Forge Studios, not a third-party asset: the glTF container is written from arithmetic by a generator committed beside it, with no exporter and no third-party model, texture, rig or animation involved (CONSTITUTION.md §11.3). The copy here is byte for byte the repository fixture, which the two 3D templates also ship.

• Bind-pose extent: the 32 vertices span 1.0 × 1.1 × 0.3 metres, from y = 0.35 to y = 1.45, with the origin on the ground below them; the rig is a torso, hips and two arms, and has no legs. 48 triangles.

models/emissive-strength-test.glb — 10 668 bytes#

Five unit cubes in a row on a reference card, three units apart. Every cube's material declares the same emissive colour, [0.1, 0.5, 0.9]; the leftmost carries no extension and the four to its right carry KHR_materials_emissive_strength at 2x, 4x, 8x and 16x, so their emissive runs far past 1.0. That is what bloom needs and what no hand-written ignifx material can express — the material format's emissive is sRGB and Color.srgbToLinear clamps it — so the example draws a second, generated row beside it to show the difference. bloom overrides the card's FlatBackdrop material with a near-black of its own through Model.materialOverrides.

Vendored unmodified, byte for byte as Khronos publishes it, which is the one deviation from 04-examples-platform.md §5.1 rule 5 in this file besides models/fox.glb's. Running it through _tools/compress-model.ts grew it to 11 488 bytes: the file's only image is a 741-byte grid texture that the pipeline re-encodes to a 1024-pixel JPEG, and JPEG rings on grid lines. There is nothing else for the pipeline to do — the model carries no meshopt compression, no quantisation and 90 triangles.

environments/studio.env — 205 260 bytes#

A prefiltered softbox studio environment — a specular cube map plus spherical harmonics — in Babylon's .env container. It is the image-based lighting the hero is lit by and the skybox behind it.

environments/studio.environment.json — 129 bytes#

The ignifx environment description that loads the .env above with its skybox turned off. The probe's cube map is a mid-grey softbox room: correct as image-based lighting, wrong as a backdrop behind a product shot, and Environment.blur cannot darken one without softening the other. So the IBL is installed and the background is left to the example, which draws textures/backdrop.png on an inverted sphere. The repository's own file.

environments/brdf-lut.png — 23 494 bytes, 256×256 RGBA8#

The split-sum BRDF lookup table Babylon Lite's loadEnvironment takes as a required parameter — it decodes the table from a pre-baked RGBD PNG rather than computing it, "matching BJS's embedded environmentBRDFTexture, for pixel-perfect parity". rendering.brdfLut defaults to this exact address (environments/brdf-lut.png, DEFAULT_BRDF_LUT_ADDRESS), so no example has to name it. This file is the base64 payload of Babylon.js's _environmentBRDFBase64Texture, decoded byte for byte, with nothing re-encoded; it is byte-identical to tests/fixtures/assets/brdf-lut.png.

textures/backdrop.png — 2 291 bytes, 512×512 RGB#

One soft elliptical pool of light, painted into the texture and drawn unlit and doubleSided on the inside of a 20-metre sphere that pbr-model turns so the pool sits behind the subject. Everything outside the pool is near-black, which is how the hero's frame gets quiet edges: the engine has no vignette pass, so the falloff is in the scene. Its bytes look far too dark on paper — #040507 at the edges and #0D1017 at the centre — because the generator states the tones it wants on screen, #0D1015 and #1F2530, and solves for the bytes that produce them: an unlit surface is sampled as linear data, multiplied by the exposure and lifted hard by the shadow end of ACES, which was measured as frame = 4.983 × byte ** 0.721 at this scene's exposure of 0.8 (a staircase of known bytes rendered into the scene and read off the frame at 1280×720, 2026-09-07).

One tile of the grid the kit's ground plane is covered with: a white cell with a two-pixel darker line on its low edges, repeated one tile per metre by MeshAsset.ground's uvScale. It is a texture rather than a shader because ignifx declares "type": "shader" in the material format and rejects it at runtime with IGX-0708.

audio/*.wav — five clips, 90 234 bytes#

Everything audio-mixer plays. They are the repository's own synthesised audio: sines, seeded white noise and a one-pole low-pass computed by tests/fixtures/assets/audio-templates/make-template-audio.mjs and written through that script's hand-written RIFF/WAVE encoder. Nothing here was downloaded, no audio library is involved, and no third-party sound library is copied, derived from or redistributed (CONSTITUTION.md §11.3). The five files are byte-identical copies of the set the 2d-topdown template ships, which is the A-minor set of the four — so the mixer's pads, its UI click and its music pad are all in one key.

Mono 16-bit PCM WAV. @ignifx/audio decodes .mp3, .ogg, .wav, .webm and .flac (AUDIO_FILE_EXTENSIONS); WAV is used because these files are already small enough that a lossy re-encode would only cost quality, and because a WAV's duration is readable under Node, which .mp3/.ogg are not.

The 2D examples' sheets and documents — 2d/*#

Four examples share one small set of files: tilemap, sprite-animation, platformer-controller and physics-2d. Two of the sheets are Kenney's, cropped; three are the repository's own generated template art, copied; and every .atlas.json, .tilemap.json and .spriteanim.json beside them is generated from those sheets and from the two hand-authored Tiled maps by examples/tilemap/tools/build-2d-assets.ts (see Provenance).

2d/tiny-town.png — 3 799 bytes, 203×135, and 2d/tiny-town.atlas.json#

Kenney's Tiny Town tile sheet, cropped to its first eight rows: grass, dirt, trees, roofs, walls, doors and fences — the ninety-six tiles the village in tilemap is built from. The three rows left behind are castle walls, arches and inventory props, and are not shipped. Nothing else in the 130-file pack is here: not the per-tile PNGs, not the previews, not the samples.

The crop is rectangular and on the grid, which is what lets gridAtlas cut it: the atlas beside it names the frames town_0 to town_95, which is exactly the naming @ignifx/2d's Tiled importer gives a tileset called town.

2d/props.png — 3 492 bytes, 227×151, and 2d/props.atlas.json#

Kenney's Pixel Platformer tile sheet, cropped to the first twelve columns of its first eight rows: the ground tiles, the crates and the coin physics-2d throws. The eight columns left behind are water, foliage and a number font. Frames are props_0 to props_95.

2d/villager.png, 2d/runner.png, 2d/terrain.png and their documents#

The repository's own generated 2D template art, copied byte for byte out of templates/2d-topdown/assets/ and templates/2d-sidescroller/assets/, where tests/fixtures/assets/2d-templates/make-template-art.mjs writes them. No image library, no exporter and no third-party pack is involved: every pixel comes out of arithmetic in that generator (CONSTITUTION.md §11.3).

• villager.png — 40 frames: an eight-frame walk and a two-frame idle in four facings. Its .atlas.json and .spriteanim.json are the template's own, copied with the image and atlas references renamed; the frame names and clips are unchanged, because they carry meaning a grid atlas would throw away.

• runner.png — 14 frames: a four-frame idle, an eight-frame run, and a jump and a fall pose. Same treatment.

• terrain.png — eight side-on tiles: ground, dirt, two 45-degree slopes, a one-way plank, brick and two cliff edges. Its atlas is generated with gridAtlas, as terrain_0 to terrain_7, because the Tiled map in platformer-controller addresses it by index.

2d/village.tilemap.json and 2d/course.tilemap.json#

Two hand-authored Tiled maps, converted. The .tmj.json sources are committed beside the examples that load them — examples/tilemap/village.tmj.json, forty by twenty cells in three tile layers and an objects layer, and examples/platformer-controller/course.tmj.json, fifty-six by sixteen with two ramps, a pit, one-way planks and a one-metre ledge — and the generator runs each through @ignifx/2d's importTiledMap and run-length encodes the result. No map from a third party is involved.

Note on CC-BY-4.0#

docs/standards/coding-standards.md §13 lists the licences ignifx accepts for dependencies (Apache-2.0, MIT, BSD-2/3, ISC, 0BSD, Unlicense, Zlib). CC-BY-4.0 is not on that list, and studio.env is CC-BY-4.0. It is a redistributed sample asset rather than a dependency, and CONSTITUTION.md §11.3 asks only that such an asset be licensed for redistribution with its attribution recorded — which this file does, and which the site republishes at /examples/attribution/. The same reasoning, and the same two files, are already recorded in tests/fixtures/assets/ATTRIBUTION.md. Nothing here reaches a create-ignifx template, so no attribution requirement travels to a game made from one.

Note on the SIL Open Font License#

fonts/share-tech-mono.ttf is OFL-1.1, which is not on coding standards §13's dependency list either, and the same reasoning applies: it is a redistributed sample asset, not a dependency. Two of the licence's conditions travel with the file and would bind anyone who copied it further — the font may not be sold on its own, and a modified copy may not carry the reserved name "Share". Nothing here reaches a create-ignifx template.

Provenance#

Run from the website package. Every command is reproducible and every output is committed, so a site build never fetches from a third party (04-examples-platform.md §5.1 rule 4).

What the model pipeline deliberately does not do#

Babylon Lite 1.27.0's glTF loader declares KHR_texture_basisu, KHR_texture_transform, EXT_meshopt_compression and the KHR_materials_* set, and declares no KHR_draco_mesh_compression and no EXT_texture_webp (checked against packages/core/node_modules/@babylonjs/lite/index.d.ts). So:

• No Draco. The loader cannot read it.
• No WebP textures. The loader cannot read them.
• No meshopt. It is declared, but its runtime decoder is normally fetched from a CDN and CONSTITUTION.md §9.1 forbids a third-party request at runtime.
• No KHR_mesh_quantization. Nothing in this repository exercises it, and shipping an asset whose accessors are a different component type on the strength of a declaration is not a thing to discover on a visitor's machine.
• No KTX2. KHR_texture_basisu is declared, so this is worth revisiting when a toktx binary is on the machine that runs the pipeline. Resized PNG and JPEG got the hero to 12% of its original size, which was enough.

_tools/compress-model.ts prints the before and after sizes, the texture count and format, the SHA-256, and the geometry extent on every run. The extent is what the example's MODEL_SCALE constant is derived from, so it is worth reading.
