Hi People.

I am trying to insert a shader field into the UserData of an object. It almost works, but there is a problem I could not yet solve. The UserData field is inserted successfully and shows up in the Attribute Manager. But I cannot insert a shader into it, it just doesn't work. When viewing the field in the UserData manager, I can see the "Interface" part missing.

"Shader Field" was inserted by my code, "Data" was inserted using the UserData manager.

This is the exact code I use:

    def add_shader_pressed(self, op) :  
      name = c4d.gui.RenameDialog('Shader Field')  
      if not name:  
          return  
  
      accept = c4d.BaseContainer()  
      accept.SetString(c4d.Tbaselist2d, "")  
  
      container = c4d.BaseContainer()  
      container.SetString(c4d.DESC_NAME, name)  
      container.SetString(c4d.DESC_SHORT_NAME, name)  
      container.SetLong(c4d.DESC_VERSION, c4d.DESC_VERSION_ALL)  
      container.SetBool(c4d.DESC_ANIMATE, True)  
      container.SetLong(c4d.DESC_CUSTOMGUI, c4d.CUSTOMGUI_TEXBOX)  
      container.SetContainer(c4d.DESC_ACCEPT, accept)  
      container.SetBool(c4d.DESC_SCALEH, True)  
      container.SetLong(c4d.DESC_PARENTGROUP, c4d.ID_USERDATA)  
  
      # Search for a free UserData id.  
      free_id = 1  
      userdata = sorted(op.GetUserDataContainer(), key=lambda x: x[0][0].id)  
      for id, data in userdata:  
          uid = id[1].id  
          if uid >= free_id:  
              free_id = uid + 1  
  
      # Insert the shader field into the objects' UserData.  
      descid = c4d.DescID(c4d.DescLevel(700), c4d.DescLevel(free_id))  
      success = op.SetUserDataContainer(descid, container)  
      if not success:  
          c4d.gui.MessageDialog('fatal error, could not insert userdata.')

What am I missing?

Thanks in advance,
Niklas

I also noticed that UserData created with this code is not accessible from XPresso, although I have
added the following lines to the code:

        container.SetBool(c4d.DESC_INPORT, True)  
      container.SetBool(c4d.DESC_OUTPORT, True)

Update: When I use the container of an existing UserData field and insert it as a new field, it works.. :/

Nevermind, I figured it out. :)

    def add_shader_pressed(self, op) :  
      name = c4d.gui.RenameDialog('Shader Field')  
      if not name:  
          return  
  
      accept_shaders = c4d.BaseContainer()  
      accept_shaders.SetString(c4d.Xbase, "")  
  
      container = c4d.GetCustomDataTypeDefault(c4d.DTYPE_BASELISTLINK)  
      container.SetString(c4d.DESC_NAME, name)  
      container.SetLong(c4d.DESC_CUSTOMGUI, c4d.CUSTOMGUI_TEXBOX)  
  
      op.AddUserData(container)
