A PBR (Physically Based Rendering) material to be used on 3D objects. [StandardMaterial3D]'s properties are inherited from [BaseMaterial3D]. [StandardMaterial3D] uses separate textures for ambient occlusion, roughness and metallic maps. To use a single ORM map for all 3 textures, use an [ORMMaterial3D] instead. $DOCS_URL/tutorials/3d/standard_material_3d.html
