Formats, materials, lighting and export — written around the jobs people actually do. No filler, no affiliate detours; every claim maps to a feature or file this site ships.
A complete walkthrough: type or upload a mark, extrude it, pick from 71 PBR materials, light it with 8 environments and export PNG, GLB, OBJ, STL or video — entirely on your device.
GLB is the binary container form of glTF 2.0. Same spec, same PBR materials — different packaging. When to ship which, and how to convert between them locally.
OBJ carries geometry and UVs but no PBR materials; GLB carries a full scene with physically based shading. Which to pick depends on where the mesh is going.
STL is geometry-only: triangles, no color, no units. How to prepare an extruded logo for a slicer — depth, bevels, thin walls and bed orientation.
Physically based rendering in three parameters: metalness, roughness, and clearcoat/transmission for the fancy cases. How the site's 71 presets map onto them.
Chrome lettering is metalness 1 with near-zero roughness reflecting a strong environment. How to get mirror chrome, brushed steel and gunmetal reads from the same preset family.
Good gold is warm base color, metalness 1, roughness in the 0.1–0.3 band, and warm-key lighting. Where each of the site's gold presets fits: solar, clean, brushed, rose.
Real glass in a browser: transmission near 1, IOR ~1.5, and why frosted glass is just roughness applied to refraction. Clear glass vs frosted, and when glass beats chrome.
Recording motion straight from the WebGL canvas: MP4/WebM capture, frame-rate honesty, loop points, and the motion presets — Spin, Float, Reveal — that cut cleanly.
Extruded text is cheap geometry — typically a few thousand triangles — but bevel segments and curve resolution multiply it. Budgets for web, game engines and print.
Two honest paths: vector/bitmap tracing into an extrusion (deterministic, print-perfect) and on-device neural generation (volumetric, from photos or prompts). When each wins.
FBX is Autodesk's proprietary interchange format — ubiquitous in DCC pipelines, awkward on the web. What an FBX holds, why importing works but exporting from a browser doesn't.
