Hi, you cannot, because the data container of a BaseList2D is not dynamically typed (like Python itself), but bound to data types specified in its description. If you want to change the data type of an user data element, you will have to modify the description of that element via GetUserDataContainer and SetUserDataContainer. There is also no 2D-Vector type in Cinema, only the crosshair thing custom GUI which you can apply to a Vector description element. Cheers, zipit

hi, your question is sometimes not obvious Even with the scene it's a bit compicated. What i can say about your code is that you should be more defensive in your code. Always check the value before continue. For example what if the object is not found ? You should continue to the next item or stop ? for item in spline_UD: rs_mat = doc.SearchObject ("S" + str (item) + " Gas") if rs_mat is None: # Because we don't have object to continue, we iterate to the next item. continue ... Cheers, Manuel

Got it. Thanks, again, zipit for you answer.

Cool! Thanks.

Got it. Thanks.

@PluginStudent said in Remove object from layer: op[c4d.ID_LAYER_LINK] = None op[c4d.ID_LAYER_LINK] = None c4d.EventAdd() did it! Thanks! As you can tell from my previous code, I am hacking my way through Python. If you saw the rest of it, you would probably have to sit down and maybe drink a Gatorade. Or something stronger.

Ah! Okay. Thanks.

I figured out the problem. I needed to assign the UD in Main.

make sure to pass a str value aka str(yourMessage) if this doesn't solve the issue open a new topic Cheers, Maxime

@Swinn is None did the trick. Thanks.

Yes, Thanks.

Problem solved. The Volume Mesher is to blame. Putting it in a Connect object and using that as the clone object did the trick.

@m_adam Cool. Thank-you for your time and patience.

Hi @Swinn are you sure in your script you define in line 19/20 settings[c4d.VOLUMETOMESHSETTINGS_ISO] = -5.51 settings[c4d.VOLUMETOMESHSETTINGS_ADAPTIVE] = 0.0 With the same value, you got in your volume mesher object? The voxel range threshold can't be directly passed as an argument, but you can expand this parameter in the volume mesher and then you get the Use Absolute Value (ISO) check box, which let you choose an ISO value. Cheers, Maxime.

@m_adam Thanks Maxime, I'll check that out. The customer was using R23.110
