import poser
import string
import aasubrs
reload(aasubrs)
scn = poser.Scene()
for a in scn.Actors():
    if a.IsLight():
        print "found light ",a.Name()
        a.SetShadow(1)
        a.Set??????????(0.5)
poser.ProcessCommand(1559)
#scn.DrawAll();

In this Python script, as run under Poser 7, what Poser Python function should I call to set the parameter called "Shadow" in a light's parameter box in Poser 7?

In Poser 7 I see the checkbox "Shadows".
The Python method is:-

SetShadow(1) #shadows off
SetShadow(0) #shadows off

The dials are set with:-

SetShadowBiasMax(value) # float value
SetShadowBiasMin(value) # float value
SetShadowBlurRadius(value) # float value

If I recall correctly the Properties panel will not update unless you manually force it by switching to the Parameters panel and back again.

p=a.ParameterByCode(poser.kParmCodeDEPTHMAPSTRENGTH)
p.SetValue(0.5)

In Poser 7 you can use lites = scn.Lights()  instead of getting and filtering the actors list.

Thanks. It works.
