How do I attach the ends of models together? Similar to Archimedes for example?

You can write your topic however you want, but you need to answer these questions:

1. What do you want to achieve? Keep it simple and clear!
   I’m looking to make a way to tile the ends and starts of models together.

2. What is the issue? Include screenshots / videos if possible!
   I’ve tested the game and when models spawn I notice that they seem to not spawn on the end of the other model but instead on the inside, clipping through. I have created a boundary box for the model to let it tile easier but it’s not working!

3. What solutions have you tried so far? Did you look for solutions on the Creator Hub?
   As mentioning before, I have tried to use a boundary box. I also did some research.

After that, you should include more details if you have any. Try to make your topic as descriptive as possible, so that it’s easier for people to help you!

Got it working after altering the pivot!
