How to Use the Terrain Editor in Roblox Studio (Step-By-Step Guide)

Have you ever wondered how to create a terrain in Roblox Studio? Well, today we’ll go over the basics of the Terrain Editor, how to shape a landscape, and create your very own terrain in Roblox Studio. This is perfect for beginners who are still nailing down the basic functions of the game and want to improve their skills. Be sure to follow along and let’s get started!

Getting Started with Terrains

The Terrain editor allows you to create realistic terrain environments, like bodies of water, hills, mountains and so much more. Mastering this skill will be crucial when you start building more advanced game worlds.

Let’s shape a landscape to learn the basics of the Terrain Editor.

Creating a Landscape

Log into Roblox Studio or download it if you haven’t yet > open up a Base Plate

Today we’re going to make a simple landscape, a lake, and a few hills to teach you the basics of terrain and modeling. 

The first thing you want to do is click the Editor under the Home tab at the top of your screen.

The Terrain Editor will pop up on the left-hand side as a panel with three tabs: 

  • Create
  • Region
  • Edit

Tap the Edit tab > Add

Where it says Plane Lock, select Manual which allows you to edit the plane.

Adjust the level of the plane to your desired height. We placed our plane just below the spawn point. Once it’s where you want, tap Apply (blue button).

Brush Settings

There are three different brush settings you can use to add terrain. 

  • Sphere
  • Cube
  • Cylinder


Tap on a cube. You’ll be able to adjust the base size, height, and many other features on this screen.

Make the cube as big or as small as you want by adjusting the base size and height. 

Hot Tip: If you want to adjust the base size and height separately, click the lock button.

Drag and drop the terrain wherever you want using your mouse.

You should now see a grassy square-shaped piece of land in your plane.

Add a Lake

Now, let’s add a small lake, just to spice things up.

You’re going to subtract some of the land that you have right now to make room for the lake. To do this, in your Terrain Editor, select Subtract under the Edit tab, and choose a brush setting (we chose a sphere). 

Change the plane lock to Auto so you can start modeling on top of the terrain you just added. You should see the brush on top of your terrain now.

If you don’t do this, your brush will be stuck to the original plane that you created at the beginning.

Left-click your mouse to start carving out the shape of a lake. This doesn’t have to be perfect. Just have fun!

Once you’re done, select Add from the Terrain Editor > select Water (under Material Settings) > adjust the Base Size and Height to make the water fit into the lake (left click to place).

Now you officially have a lake! Great job!

Adding Hills and Mountains

So far you’ve learned how to build a terrain and some water to create a natural lake. Now let’s learn how to create hills using the Grow tool.

Select Grow under the Terrain Editor > left click and hold as you move your mouse around the terrain to make hills. These can be as wild or as mild as you’d like. 

Let the creativity flow here!

Hot Tip: The longer you hold your mouse down, the more your hill/mountain will grow.

Now, you should have a small (or big) hill in place.

Tools To Be Aware Of


If you want to make some valleys, canyons, or trenches within your terrain, select Erode, hold the left click, and perform the same motions wherever you want the terrain to be eroded.


If you ever create sharp edges in your terrain that you want to soften, select the Smooth tool within the editor to smooth those out.


To make your terrain, hills, or mountains the same height, use the Flatten feature.

In nature, nothing is perfect or symmetrical, so play around with the different features and shapes until you make something you’re happy with.


If you don’t want to change the shape of, say, a valley you just created but want to add new material, select the Paint tool, choose your material, and apply it to your desired area. 

We added some mud to our valley here.

Adding Trees or Other Objects

Let’s add a tree to complete the new terrain we just designed. 

Under the Home tab select Toolbox > Marketplace > Search “Tree” > pick one that you like

Adjust the size and placement of your tree as you see fit.

If you’re not sure how to move, scale, and adjust objects in Roblox Studio, check out our other blog post here that will walk you through step-by-step how to do it. 

And there you have it. Your basic landscape is now complete!

The Takeaway

Even if you’re brand-spankin’ new to Roblox, you don’t have to feel overwhelmed. Building a terrain within Roblox can be relatively easy, as we’ve shown you here. The more you play, experiment and practice, the better you get. And before you know it, you’ll be creating games like the pros!

My son (newly 15) did the 6-week program and I thought it was very good for him. First of all, it gave him something to do this summer (no typical job due to COVID), and second, I think it made him think about things other than math, which is his favorite subject and thing to do! I also appreciated the one on one mentoring sessions in addition to the weekly group session.

I also liked that he had homework to do between sessions. I thought that he received a lot of attention from the LogoLife founders and instructors and that the info given to him to develop was detailed and effective, and tailored to his passions.

A productive and comprehensive teen entrepreneurship program.

The Logolife program is a truly inspiring and innovative way to teach today's teens the skills they will need to adjust in this changing world. As a single parent, my biggest concern has been to prepare my kiddos for the future, but what the future holds is anybody's guess.

When I found Logolife, I was so excited because it teaches kids to adapt to changes and to create their own path forward. I am especially impressed that they encourage kids not to be afraid of failure, but to accept that trial and error is a meaningful part of the process and that being gritty and tenacious can be even more important than having natural talent or ability.

While they learn to capitalize on their strengths, they are also encouraged to grow through their weaknesses and to use what they have to bring value into the world around them. All of us know that what our schools aren't able to prepare our kids for the future or to make them successful in life.

Education alone isn't the answer; the answer is the right education. I am so proud to encourage every parent to investigate Logolife as an option for their children.

If you start by attending the parent meeting I think you'll find that every point of their program is something today's teens need to not only hear, but embrace. It also helps that everyone associated with the program is completely professional, helpful, gracious and enthusiastic.

My daughter and I have had nothing but a positive and uplifting experience with Logolife. I give them my very highest recommendation!
