Building Better Rooms – Replicator Tutorial

Hey everybody, it’s Under My Cap. Welcome back. Today I’m going to show you how to use the Replicator in Rec Room.

Behind me, I have these vending machines. When I click one, it spawns an item. Those items are replicated—they aren’t “real” items in the usual sense. They’re clones created by the Replicator, and you can return them. In this post, I’ll walk you through how to set up and use the Replicator.

Enable Beta Tools in Your Room

First, you need to enable beta tools in your room.

To do that:

Open your watch, go to This Room, then Settings, then Main Settings. Scroll all the way down until you find the toggle called Allow Creative Tools Beta Content, and turn it on.

Important: Once you turn this on, you can’t turn it off, so make sure you’re okay with that before enabling it.

Spawn the Replicator

Next, pull out your Maker Pen.

Open the Maker Pen menu, go to Palette, then Circuits, and search for Replicator. The Replicator appears as a purple beam. Click it to spawn it into the room.

Once it’s placed, you’ll see the Replicator as a purple glowing device. Anything you connect to it can be cloned (replicated) into the room.

Understand the Replicator Chip

When you spawn a Replicator, it also comes with a chip. This chip is essentially the “brain” that controls how replication works.

On the chip, you’ll find several key inputs:

Spawn Next Object (execution): Triggers the Replicator to clone whatever is loaded onto the Replicator plate and spawn it into the world.

Position: Where the replicated object should appear. By default, it starts at 0,0,0,0.

Orientation: Controls the rotation of the spawned object. This is straightforward—it just changes which way the replicated object faces.

Assign to Player: Lets you assign the spawned object to a specific player so that only that player can interact with it.

Player: Specifies which player the spawned object should be assigned to (if you’re using assignment).

Load an Object into the Replicator

In Rooms 2, you’ll use containers. You can think of the Replicator as working like a container system: you load a contained object into it, and it can spawn copies.

For example, I spawned one of my creations: a cat. Let’s say we want to replicate that cat throughout the room.

Here’s what you need to do:

First, make sure your object is inside its own container. In my case, the entire cat is contained properly.

Then open your Maker Pen and select the Wire tool (the second purple button next to Configure). Click the cat, then drag the wire to the Replicator.

When you do that, the object will snap onto the Replicator. That snap is your confirmation that the object is now inside it.

Spawn a Replicated Copy

To keep things simple, we’ll spawn a replicated cat at the same location as the current cat.

Grab the object reference board (the one with the identifier at the top) and drag it to the Position input on the Replicator chip. This will automatically create a Get Position chip, which is fine—we’re just grabbing the position from the current object.

Then connect that same position output to Orientation as well. (If you accidentally create an extra chip while wiring, don’t worry—just reconnect it correctly.)

Now, click Spawn Next Object. You should see another cat spawn in. Sometimes it may appear slightly glitched or overlap, but it should still be there.

One thing to note: when you drop your Maker Pen, the object that’s loaded into the Replicator may disappear from where it was originally placed. That’s why you may suddenly see “duplicates” after spawning—because the Replicator is now managing the contained object for replication.

If you click Spawn Next Object again, you’ll spawn another replicated cat into the room.

Why Replicators Are Useful

The cool part is that, because this works with containers, you can also include circuits inside the replicated objects. That means your replicated items can still be interactive—especially if you’ve built them with things like interaction volumes and other circuit systems.

That’s a brief introduction to using the Replicator. It can be used for a lot of different purposes, and once you get comfortable with wiring it up, it becomes incredibly powerful for rooms and gameplay systems.
