Engine tests

AI 3D engines, tested on the same blocks

Name: AI 3D model generators tested on the same blocks
Creator: Vox Land

Most comparisons give each engine a different prompt or picture. We build one block-out, send it to every engine, and measure what comes back.

Vox Land routes to all of them and makes none of them.

Results by block-out

One table per test: every engine got the same blocks, so the rows compare directly.

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.
