Hi Sebastian,

For example, a steel cube (e.g. reflectance = 1.12) should reflect more than a plastic cube (e.g. reflectance = 0.6) for a real sonar. In this case, I need to pass this "reflectance" value to shader for each object present in the scene. > > What kind of input geometries do you use?

Initially all parts of the same object will have an unique reflectance model. ...
