global_settings {
    adc_bailout float
    radiosity { adc_bailout float }
    photons { adc_bailout float }
}

It can be used together?
It can be used at the same time?

max_trace_level and photons {max_trace_level}
It is possible to write so?
 global_settings {
    max_trace_level int
    photons { max_trace_level int }
}


radiosity { subsurface off} == subsurface {} ???
subsurface { radiosity off} == radiosity {} ???

or
radiosity block in global settings disable(turn off) if subsurface { radiosity
off} ???
subsurface block in global settings disable(turn off) if radiosity { subsurface
off} ???

global_settings{adc_bailout float} will set the adc_bailout globaly for 
normal rays and photons tracing. It default to 1/255.

global_settings{radiosity{adc_bailout{float}} will set the adc_bailout 
specificaly for the radiosity computations. This value have a default 
value that will be used if not specified.

global{settings{photons{adc_bailout{float}} will set the adc_bailout for 
photons tracing only. If set, it will replace the general value only for 
the photons. If not set, it will default to the general value.

All 3 are optional, and all 3 can be used in the same scene.

The same hold true for max_trace_level. The setting for the photons can 
be used to set the max_trace_level to be used for the photons 
differently than the general case. You may need to allow the racing of 
photons for up to 255 reflections and refractions, but don't need that 
much anywhere else...

Both are optional and can be used in the same scene.

radiosity{subsurface off} is the default value. Setting 
radiosity{subsurface on} will allow the radiosity computations to be 
affected by the transucency of surfaces. Normaly (off), radiosity will 
ignore the effect of subsurface light transport.

subsurface{radiosity off} is also a default value. Setting it to on will 
allow subsurface to be affected by radiosity. Normaly (off), subsurface 
will ignore any radiosity.

Alain, thanks very big! Thank you.
