max_trace_level determine how many surfaces a ray can interact with 
before the tracing process stop.
Currently, it ignore simple transparent surfaces where there is no 
reflection and no refraction.
The default value is 5. That mean that the fifth surface encountered is 
treated as black, opaque and non-reflective.
That's a global_settings parameter.

global_settings{
	max_trace_level 25
  }
