+PhysInOne is divided into three primary splits: **Train**, **Val**, and **Test**.  
+
+- Train Split: contains 122,988 scenes.  
+- Validation Split: contains 15,411 scenes.  
+- Test Split: contains 15,411 scenes.  
+
+Each split is generated using **completely distinct 3D meshes, and backgrounds** to ensure that models cannot overfit to shared geometry or scene layout across splits. No scene is repeated between splits, and objects, lighting, and environment setups are independent for each split.  
+
+This design guarantees that training, validation, and test sets are fully separated in terms of visual content and scene composition, providing a robust benchmark for generalization and physical reasoning tasks.
