EgoGenEval benchmark targets physical consistency of image generators under ego-motion

A new arXiv paper introduces EgoGenEval, a benchmark aimed at measuring how well visual generators maintain physical consistency when a viewpoint moves, rather than judging output on image quality alone. The authors argue that current generators can produce realistic-looking images yet break physics under ego-motion, which limits their usefulness for spatial reasoning and embodied planning. Existing benchmarks, they note, mostly assess single images or single-step quality.
