You can write your topic however you want, but you need to answer these questions:
What do you want to achieve? A Model of around 20 parts being tweened
What is the issue?
What solutions have you tried so far? I have tried To tween it like that however only the part I said to tween tweened, I have tried welding them still nothing?
I am just interested on how to tween a model as a collective all parts on one script essentially (easy if possible)
