RelationVGGT finds cross-view relational masks from unposed multi-view images, given a subject mask and relation phrase. It combines DINOv2 and Pi3 features, then uses subject-conditioned attention to predict relation features on target-view pixel grids rather than searching a reconstructed 3D volume. On three benchmarks it achieves macro mIoU 0.382 and mAcc 0.549, but trails RelationField on cluttered LERF scenes.
