Hello!
I would like to automate the replacement of materials loaded in Alembic.

How can I change the attached python code to replace the material with a material with the same name as the one applied in Alembic?

I would appreciate your advice.

I am new to the forum, so please forgive my unfamiliarity.

import re
import c4d

def main():
  doc = c4d.documents.GetActiveDocument()
  oplist = doc.GetObjects()
  if not oplist: return
  matlist = doc.GetMaterials()
  if not matlist: return
  if oplist:
      for op in oplist:
        opname = op.GetName()       
        mat = doc.SearchMaterial(opname)
        if not mat:
          for mat in matlist:
              mname = mat.GetName()
        mname = mat.GetName()
        match = re.match(opname, mname)
        if match:
          textag = c4d.TextureTag()
          textag.SetMaterial(mat)
          textag[c4d.TEXTURETAG_PROJECTION]=c4d.TEXTURETAG_PROJECTION_UVW
          op.InsertTag(textag)
  c4d.EventAdd()
if __name__==‘__main__’:
  main()
