@Dunhou Thanks for the reference but yea I'm unfortunately using the xpresso here instead of the new node editor. Which in all regards, an unfortunate scenario is xpresso is not integrated to the new node editor. @m_adam Gotcha. Thanks. Looking forward to the update.

Hello, Some symbols are not exposed to public. There's no particular reason for that. There's no real place where all exposed symbols are. (and we agree it's could be nice) To know if a BaseObject is a camera (or something) you can use IsInstanceOf You can also send a message using the ID MSG_GETREALCAMERADATA : with an alembic generator you can use this code : camera = doc.GetActiveObject() if camera is None: return if camera.IsInstanceOf(c4d.Oalembicgenerator) == False: return # This example tries to get the internal camera from a generator. # Typically used with the Alembic Generator camera. data = {} data["res"] = None res = camera.Message(c4d.MSG_GETREALCAMERADATA, data) if res: camera = data["res"] print("Camera: " + camera.GetName()) For your next threads, please help us keeping things organised and clean. I know it's not your priority but it really simplify our work here. Q&A New Functionality. How to Post Questions especially the tagging part. I've marked this thread as a question so when you considered it as solved, please change the state Cheers, Manuel

Once again, thank you, Manuel. I had to do a few changes and it is working now. I even made it select the faces that are within a certain angle from the camera. Here is my code: for i,poly in enumerate(faces): a,b,c,d = poly.a,poly.b,poly.c,poly.d pta = points[a]*mg ptb = points[b]*mg ptc = points[c]*mg ptd = points[d]*mg v1 = pta-ptb v2 = ptb-ptc normal = v1.Cross(v2) normal.Normalize() if c != d: center = c4d.Vector((pta.x+ptb.x+ptc.x+ptd.x)/4.0,(pta.y+ptb.y+ptc.y+ptd.y)/4.0,(pta.z+ptb.z+ptc.z+ptd.z)/4.0) else: center = c4d.Vector((pta.x+ptb.x+ptc.x)/3.0,(pta.y+ptb.y+ptc.y)/3.0,(pta.z+ptb.z+ptc.z)/3.0) direction = cam_off - center norm_dir = direction.GetNormalized() angle = NINETY - normal.Dot(norm_dir) if (angle > 0.0 and angle < max_ang): selection.Select(i)

I found a reply here. https://developers.maxon.net/forum/topic/11447/get-message-from-treeview-gui-dialog/2

Thanks, that solved the issue. -Pim

Ok, something to think about. Never considered using GeuserArea.LayoutChanged when changing the UA size. I will give it a try.

Thank you. I will look into it and try it.

Thanks for the answer. And yes, you are fully correct. Things should not be done in DrawMsg()

Yes, that solved it. Thanks.

@PluginStudent @s_bach Thank you for the response. Both works as expected. RE: don't know why you think you need two groups. Just for reference, I was thinking of this logic if self.mode == True: self.Group1_Layout() else: self.Group2_Layout() Anyhow, no further action required

Thanks for the explanation. Works as expected.

@m_adam Hi Maxime, thank you for the quick reply and insight into this. I look forward to trying this.

@r_gigante Thanks for the response. Works as expected.

hello, To retrieve the active object you have to iteration trough the hierarchy. (even GetActiveObject) In Python, GetActiveObjects is calling a c++ function so with lots of object it will be faster than iterating the hierarchy with python functions. We don't know what the limit is. To mesure that you have to make a bunch of tests with different scenarios and get the mean. Cheers, Manuel

@m_magalhaes Thanks for the confirmation.

@r_gigante Thank you, Riccardo! I don't know how I missed that in the documentation, but it is what I needed.

Thanks! So will find some workaround.

@r_gigante Gotcha. Thanks for the warning.

The bug is fixed in S22. Cheers, Maxime.
