 Material properties, such as roughness, permittivity, and index of refraction, influence how sensors like cameras, radars, and lidars perceive and interact with objects.
 However, existing formats for materials in 3D models lack a standardized way to represent and manage multi-spectral materials, which can lead to inconsistencies in simulation scenarios and are not exchangeable between simulation tools.
 
-The ASAM OpenMATERIAL standard addresses this gap by providing a robust framework for defining materials in a way that is both comprehensive, multi-spectral, and interchangeable.
