ALLUDE closes long-standing gaps in adversarial attack evaluation, uniting Unreal Engine photorealism with end-to-end differentiable rendering in a single cross-platform system. (A) fully configurable scenes, objects, attacks, lighting, and weather; (B) a rich set of built-in camera trajectories, from tight orbits to sweeping flyovers; and (C) a modernized library of CARLA maps and models, freed from legacy Unreal Engine versions for immediate reuse in current and future research
