+# MatPredict
+
+MatPredict is a synthetic dataset for material-centric scene understanding. It supports two main tasks:
+
+1. **Inverse rendering**: predict material properties such as albedo, roughness, and metallic maps from RGB images.
+2. **Material segmentation**: predict material regions or material classes from RGB images.
+
+The dataset contains rendered object variants with paired RGB images, material property maps, segmentation labels, camera transforms, and metadata.
