gain access to vray shaders [SOLVED]

code snipped of a script tag. has a userdata with a link to a specific vraydistance shader:
vrayshader = op[c4d.ID_USERDATA,1] print vrayshader[c4d.VRAY_SHADERS_LIST] # returns shader type // 54 == distance if vrayshader[c4d.VRAY_SHADERS_LIST] == 54: print vrayshader[c4d.ID_SW_OBJECTS 1_209556393] # should return include list for objects assign to the distance shader
the mayor problem is that the [c4d.ID_SW_OBJECTS 1_209556393] are causing a syntax error.
so is there a way to avoid that and read and write the include list of an vray shader? all other values exept the [c4d.VRAY_SHADER_LIST] are creating the same issue as the include list. -

Hi,
your last line looks odd, with two values as array index. I'm not sure, what you are trying to do there... so basically I'm on the side of the compiler/interpreter
Also we can not provide any support on vray in these forums. Sorry. Please try to get support from LAUBlab with vray questions.

Here you go:
import c4d #Welcome to the world of Python def main() : vrayshader = op[c4d.ID_USERDATA,1] if vrayshader[c4d.VRAY_SHADERS_LIST] == 54: cont = vrayshader.GetDataInstance() l=0 #Iterate through the ID's inside the Distance shaders BaseContainer, looking for a CUSTOMGUI_INEXCLUDE_LIST while cont.GetIndexId(l) != -1: subID = cont.GetIndexId(l) if cont.GetType(subID) == c4d.CUSTOMGUI_INEXCLUDE_LIST: #Go through the objects in the CUSTOMGUI_INEXCLUDE_LIST ( if any ) for i in xrange(cont[subID].GetObjectCount()) : print "Object = "+str(cont[subID].ObjectFromIndex(c4d.documents.GetActiveDocument(),i)) l+=1
Grabbing an objects BaseContainer, and trawling through it, is often the way to find stuff..
Be aware though - that when i was testing, i noticed the shader i linked in the UserData , did not update when the shader in the material i dragged it from was changed - ie it's a copy not a true instance or reference. So you'll probably want to find a way around that also..

Thanks ! Work great!
Where did you found that CUSTOMGUI_INEXCLUDE_LIST link?
I need this to grab all shaders in a tree

No problem.
Keep a copy of the C++ SDK docs side by side with the Python docs, because a number of things aren't included in the Python docs but can be found in the C++ version. Not everything in the C++ docs is available in the Python API though, but still really useful to have as a reference..
