Hello, everyone! Im learning python and trying to make useful stuff, but it`s hard to understand some things.

I`m writing now a simple script for Redshift users. The task is:

1. Add individual Object ID tags to selected objects (for examle, obj1 = 1, obj2 = 2 , ...)
2. Create Redshift Pazzle Matte AOVs (PM)

The trick is to make enough PM to be enough for each object that is selected in the scene.

1 PM AOV is equal to 3 objects in scene. For example I generated 9 Object ID tags. Every tag assign uniqe number for every object (1, 2, 3, ...). For each of them I need PMs where every channel is object in scene.

1. How to generate multiple PMs with uniqe names and increasing numbers for my Object IDs?
2. How to improve this code?

Thank you for your attention!

@zipit I appreciate your answer. Thank you very much!

Hello everyone!

I`m noobie and working on simple script that should generate on selected layers Redshift Object tag with checked Object ID Override. Also I need to make uniqe Object ID numbers by adding 1 to each tag.

Problem: When I make loop through tags and try to increase Object ID parameters by 1 (I need 1, 2, 3,...) it pass all the tags exept the last and make the last tag Object ID parameter equal to objects quantity (9 in my case)

1. How to increase Object ID parameters for each tags with uniqe data from 1 to {tags quantity}?
2. How to improve this code?

import c4d
from c4d import gui



def main():
    doc.StartUndo()

    selection = doc.GetSelection()
    collectedObjects = []


    if selection:
        for s in selection:
            collectedObjects.append(s)
    else:
        c4d.gui.MessageDialog('Please choose objects')


    for s in collectedObjects:
        tag = c4d.BaseTag(1036222)
        tag[c4d.REDSHIFT_OBJECT_OBJECTID_OVERRIDE] = True
        s.InsertTag(tag)
        doc.AddUndo(c4d.UNDOTYPE_NEW, tag)
        
        
        
    for tags in range(len(collectedObjects)):
        
        tag[c4d.REDSHIFT_OBJECT_OBJECTID_ID] += 1
        

        
    doc.EndUndo()    
        
        
if __name__=='__main__':
    c4d.CallCommand(13957)
    main()
    c4d.EventAdd()
