def ModifyObject(self, mod, doc, op, op_mg, mod_mg, lod, flags, thread) : reduction = c4d.BaseObject(c4d.Obend) #Bend Deforemer reduction[c4d.DEFORMOBJECT_STRENGTH] = c4d.utils.Rad(90) #Strenght = 90 degrees reduction.InsertUnder(op) #Insert bend under op op.Message(c4d.MSG_UPDATE) return True
This code display deformer but it has no effect on the geometry.

I registered this plugin as a MODIFIER
info = c4d.OBJECT_MODIFIER
Do I have to include other flags, in order to make it work with other deformers?

Seems like it's working but not in the viewport.
What could cause such behavior?

Well... I used CSTO command but now I see 2 objects in my viewport. in the rendered image, this base object is hidden and only modified geometry is displayed.

Where can I find more information about OBJECT_MODIFIER **plugins?

Hi,
the issue is actually not so much OBJECT_MODIFIER related.
You are not allowed to modify the scene from within the scene evaluation pipeline. This includes ObjectData's GetVirtualObjects(), ModifyObjects(), GetContour() and Execute() functions, also similar functions from other NodeData derived plugin types.Actually a modifier usually modifies the geometry directly, using existing deformers is at least a bit unusual, see example Py-SpherifyModifier.
But if you really have to use existing deformers to get the job done, you can still do so, even if it may be not the fastest route to go. In this case you'd clone the object, you want to modify, insert it into a temporary document, add the modifier there, execute the temporary document and then transfer the result to the object being modified in ModifyObject().
Maybe you can let us know a bit more about your final intention, then we could discuss here, what's the best way to get there.

I want to perform several modeling operations on the desired object but before this, I would like to use poly reduction, in order to simplify its geometry and then execute modeling commands.

Hi,
since R19 we have a PolyReduction class. Here's some more information in the PolygonReduction manual.
Not only will this be way easier to implement, than the above described deformer approach, but it should also perform way better.
