+## 🏆 Challenge: Scene-Aware Referential Gesture Generation at ECCV26
+
+
+Given speech, a 3D target coordinate, and a scene, generate SMPL-X pointing gestures that are temporally aligned, spatially accurate, and referentially grounded. Submissions are scored on three axes: temporal alignment, spatial accuracy, and referent recall.
