I have some cubes (created with a Python script) and I would like to set 6 different colors to all of the sides of them.
I know how to do this manually, but I have plenty of cubes (some thousands) so i'd like to automate the process: create the cube -> make it editable -> select the poligion on the side -> apply texture -> repeat this with all the sides.
I absolutely don't have any ideas how this can be done in Python, any help would be greatly appreciated.

welcome to the Plugin Café forums
I think, gr4ph0s answer more or less solves most of your questions, with maybe just creation of cubes and make editable not answered, yet. For the "make editable" part I suggest to take a look at SendModelingCommand() in conjunction with MCOMMAND_MAKEEDITABLE.

I'm trying to do a similar thing but create a selection tag based on a manual selection but am stumped on how to assign the selection to the tag.
selection = op.GetPolygonS()
primaryTag = op.MakeTag(c4d.Tpolygonselection)
I feel like there should be a command to add my selection to the tag but after two hours I'm still stumped. Any help is appreciated.

Found my missing command. Posting here in case anybody else has to go digging for this.
from c4d import gui
#Welcome to the world of Python
primaryTag = op.MakeTag(c4d.Tpolygonselection) # adds a selection tag to your selected object
primaryTag_bs = primaryTag.GetBaseSelect() # get the selection container from the tag so it can be accessed.
op.GetPolygonS().CopyTo(primaryTag_bs) # copy your live polygon selection to the selection container
primaryTag.SetName("primary") # give your new selection tag a name

Glad you found a solution yourself, I was just about to post a similar answer.

It's confusing at times because "Set" is used in so many places that "Copy" never enters my mind. Finally found an old thread that had my missing line and then it all made sense. Tough search as I kept looking for things with "Set".
thanks for looking at it.
