A procedural red marble material built using Blender's shader nodes. The material is encapsulated in a custom node group to provide easy access to key parameters. Users can adjust the scale, vein size, texture details, and distortion to customize the stone's pattern. The node group also includes specific controls for subsurface scattering, clear coat, roughness, and bump mapping to refine the surface finish. The provided Blender file includes the material setup along with HDRI lighting.
