Hi everyone !
I did a little search here and on cgtalk but couldn't find anything about the subject, and the sdk is still cryptic for me sometimes..
Is there a way to create/delete a layer, set its name, add objects to it and so on ?
I thought I can solve with this: http://chicagoc4d.com/C4DPythonSDK/modules/c4d.documents/LayerObject/index.html#c4d.documents.LayerObject
but evidently I didn't understood how it works.
Basically what I would like to do is a script that creates a new layer, sets its name to something, and add selected objects to it. I'm ok (i think) with adding objects to the layer, but i can't figure how to add the layer itself.
Any advice, example or reference I can check would be great !Cheers

Hi Massimiliano,
Methods dealing with layers are exposed in several classes: LayerObject, BaseDocument and BaseList2D.
Here's a commented code snippet showing how to deal with layers:import c4d def main() : # Create a new layer layer = c4d.documents.LayerObject() # Set layer name (Calls C4DAtom.SetName()) layer.SetName("New Layer") # Assign the active object to the newly created layer # (Calls BaseList2D.SetLayerObject()) if op is not None: op.SetLayerObject(layer) # Get the invisible root layer layerRoot = doc.GetLayerObjectRoot() # Insert the layer under the root layer.InsertUnder(layerRoot) c4d.EventAdd() if __name__=='__main__': main()

wow, that was fast :) Thanks a lot Yannick.
I wrongly interpreted a layer as an object "attribute" instead of an object itself, it makes more sense now :)Cheers

Yes, a layer is an entity inside CINEMA, not just an attribute or parameter.
LayerObject (representation of a layer) inherits BaseList2D: C4DAtom->GeListNode->BaseList2D->LayerObject.
I'll improve layers documentation because this isn't obvious.
