Support & updates

Getting help

Email hello@assetsforthreejs.com with the pack name and the address you paid with. That covers download problems, a file that is faulty or not as described, and licence questions.

Updates

Your download link always serves the current version of the pack. When we improve a pack (for example, the reduced medium and low detail levels added to several packs in September 2026, pack format 2 on 1 October 2026, which added the kit runtime, generators and per-part materials to every zip, and format 2.1 on 2 October 2026, which added instanceAssembly for drawing repeated parts as instances), downloading again gets the new files. Links last 30 days; your licence does not. Get new links any time with the email you paid with.

What a download contains

• Every component model as GLB in high, medium and low detail, meshopt-compressed and quantised.
• The same models uncompressed, for tools that do not read meshopt.
• Assembly files (JSON: parts, transforms, per-part materials and open/closed poses) and assemblies.js, which loads them.
• jstov-kit.js, the kit runtime the loader uses: layered materials (colourways, weathering), motion poses and, where the pack has one, its generator, so you can build your own layouts in code. Every part a generator can place is in the pack.
• index.html, a working example scene, plus a README with a triangle table, a catalogue file, and the licence.

What it does not contain

• No Blender project files. The models are generated by our own scripted Blender pipeline; you get the exported GLBs, which open and edit in Blender and other glTF tools.
• No rigs or animation. The models are static meshes. Moving parts (crane jibs, trolleys, hooks, machine arms and buckets, gates) are separate models, so you can animate them in code.

Tested with

The files and the assembly loader are tested in three.js 0.186 (the viewer on this site and our own scenes). GLB is an open format, and the uncompressed copies are there for other tools, but we have not tested other engines, and assemblies.js and jstov-kit.js are three.js code. Before release every pack is unzipped and loaded with no network access to our servers: every assembly, plus one generator run, must load without an error.
