Test: T-posed character

839 blocks, cartoon style: a young man in a blue T-shirt, dark grey trousers and black boots. The T-pose shows whether an engine textures both arms.

Test: Castle gate

4,518 blocks, realistic style: a stone gatehouse with two towers, battlements, a portcullis, banners and a drawbridge on chains. The test for a large building with thin parts and repeated detail.

Which one to pick

Pick Hitem3D 2.1 for high-detail sculpts you will decimate or retopologise anyway.

  • more geometry (1,959,692 vs 40,000 triangles)
Hitem3D 2.1

Pick Hunyuan3D 2 for cheap hard-surface props and buildings where one colour texture is enough.

  • 16.0× lighter files in our test (3.6 MB vs 58.3 MB)
  • fewer triangles (40,000 vs 1,959,692): less to decimate
  • quicker job (102 s vs 592 s)
  • open weights, if you want to run it yourself
Hunyuan3D 2

Quick answers

Which gives smaller files, Hitem3D 2.1 or Hunyuan3D 2?
Hunyuan3D 2: 3.6 MB against 58.3 MB on the T-posed character (40,000 vs 1,959,692 triangles).
Which follows the input shape more closely?
Hunyuan3D 2 kept more of the block-out's outline on the T-posed character: 83% overlap against 73%.
Do they give PBR texture maps?
Neither returned a full PBR set in our runs: Hitem3D 2.1 gave base colour · roughness-metal, Hunyuan3D 2 gave base colour only.
Which one is faster?
In our run on the T-posed character, the Hunyuan3D 2 job took 102 s and the Hitem3D 2.1 job 592 s, both from the same finished views. One run each: treat it as a rough guide.
Can I get OBJ or FBX?
Both return GLB only. In Vox Land, every model can also be exported as OBJ from the GLB.
Can either one rig a character?
Neither rigs characters itself. In Vox Land, any character can be rigged from the part tags on your blocks, whichever engine made it.

How we test

  1. 1Same pictures. Within a test, an image model repaints the block views once (the way Vox Land always works), and that one set of views goes to every engine, at its default settings; the table lists any that differ. Engines that take a single picture get one three-quarter view, painted from the same blocks in the same style.
  2. 2So every difference inside a test comes from the engine, not from the input. The blocks fix the shape and the proportions; the repainted views add the colours and small details every engine then shares.
  3. 3Numbers are read from the file each engine delivered: triangles, file size, texture maps. Job time is the engine's job in our pipeline (the views were painted beforehand), from a single run.
  4. 4Outline match: we draw the block-out and the model as flat silhouettes from the front, the side and above, and measure how much they overlap (intersection over union; 100% means identical outlines).
  5. 5The renders are ours: the same camera, light and orientation for every file.
  6. 6We make none of these engines. Vox Land sends your blocks to whichever one you pick, so we have no reason to favour one.
