ArXi:2604.01882v1 Announce Type: new Affordance reasoning in 3D Gaussian scenes aims to identify the region that s the action specified by a given text instruction in complex environments. Existing methods typically cast this problem as one-shot prediction from static scene observations, assuming sufficient evidence is already available for reasoning. However, in complex 3D scenes, many failure cases arise not from weak prediction capacity, but from incomplete task-relevant evidence under fixed observations.
