TRELLIS 2

Microsoft's 4-billion-parameter successor, built from one picture: dense geometry and PBR maps, but the back and the depth are its own guess.

What we saw

Works from a single picture, so we send one repainted three-quarter view; how deep the object is and what its back looks like are its own guess.
Dense and textured, with base-colour and roughness-metal maps (4K when asked for detail).
In our runs its colours drifted from the picture it was given: the red pickup came back dark brown, the character's brown hair black.
The file's orientation follows the picture: our pickup truck came back turned a quarter. Vox Land turns it to match your blocks.

Results

Left to right: the block-out it was given, the result from the front and the back, and the shape without its textures.

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.

How we test

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.
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.
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.
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).
5The renders are ours: the same camera, light and orientation for every file.
6We make none of these engines. Vox Land sends your blocks to whichever one you pick, so we have no reason to favour one.
