Hi,guys.
  I want to change some parameters of the Default Specular Layer in C4D R17,but it's not working,I don't know why?

Here is the code below:

  
import c4d  
from c4d import gui  
  
  
def main() :  
  doc.StartUndo()  
  mats = doc.GetActiveMaterials()  
  if not mats:  
      return  
  for mat in mats:  
      mat[c4d.REFLECTION_LAYER_MAIN_DISTRIBUTION] = 3  
      mat[c4d.REFLECTION_LAYER_MAIN_ADDITIVE] = 0  
      doc.AddUndo(c4d.UNDOTYPE_CHANGE,mat)  
        
  doc.EndUndo()  
  c4d.EventAdd()  
        
  
if __name__=='__main__':  
  main()  

Thank you for any help!

It's been a while since I worked with materials in Python, but if I remember correctly you need to add the layerID to your atrribute index

  
  
      reflayer = mat.GetReflectionLayerIndex(idx)  
      mat[c4d.REFLECTION_LAYER_MAIN_DISTRIBUTION + reflayer.GetDataID()] = 3
