Splitters and Mergers and Storage Limiters... Oh my!
As we get closer to v0.3 launch, we’re deep diving some of the new features within. Today, we’re going over the Belt Hubs overhaul, plus taking a look at the new Storage Limiting controls.
As a quick overview, here are the features coming in v0.3:
So let’s dive in!

[h3]Belt Hub Changes in v0.3
[/h3]
There are two ways you can build belt hubs - the boxes that merge belts together and split belts apart - in v0.3, depending on if you’ve placed the conveyor belt already. Splitters and Mergers will now appear in the variants menu for belts, and you can simply swap over and place them manually for fine-tuning.
Laid down a belt but want to add a Hub? Conveyor Belt Hubs are the first of all our buildables to be able to change the variant after they have been placed. Aim at the belt you want to change, and hit the variant button to add a Hub to your belt.

Code-wise, Hubs are still just belts under the hood. I'm sure there's a rotating belt in that black void the resources go into, and it’s definitely not some little hamsters pushing stuff around. Techtonica is animal cruelty-free. I think.
While we were adding in the ability to build stand-alone Hubs, we realized that stand-alone Hub have no purpose and sit there in existential contemplation until neighboring belts arrive.

It's right there in the code (it's not, but Lesther said it is, so take that with a grain of salt). Once you place belts on multiple sides of the Hub, it automatically sends items along the belts that connect to it.
In the current version of Techtonica, you can’t place a Hub next to a curve in a belt. The exact reasoning from days of old escape the tech team. But whatever it used to be, curves in and out of Hubs are now supported. This will make sending fuel to drills a heckuva lot easier (if you know, you know).
Hubs still take their personal space seriously when it comes to other Hubs, so you’ll need at least one regular belt in between them.

In v0.3, Storage Limiting is pretty easy to implement. Open the chest you want to limit and drag over the boxes you want marked “closed”.

Storage limiting doesn't clear the prior contents of the container! Inserters are still able to move things out of those restricted slots, but will never be able to add things back in (until you change the setting again).
Storage limiting also doesn't affect dragging and dropping items by hand. This only affects inserters and "bulk transfers," so you can safely try to move all your limestone to a chest without it going over the set limit. If you decide to drag and drop into the container, it's assumed you're engaging the manual override.
Storage Limiting was a highly requested item from our Feedback Website and Discord, and we’re stoked to implement it in v0.3.
And that's a wrap for this week's update, folks! We're buzzing with excitement for the Factory Efficiency Update, and we know you're itching to dive into all the fantastic quality-of-life upgrades coming your way.
Another Update Pack is gearing up for release in the coming weeks, so keep your eyes peeled!
In the meantime, hop on over to our Discord for some memes, questions, and to lend a hand to our fellow Groundbreakers.
Until next time, let’s get to work!
As a quick overview, here are the features coming in v0.3:
- Stack Filter Inserters
- Vertical Belts
- Quick Copy
- Replacement Tool
- Storage Limiting
