Beginning 3D Modelling with UModeler: Explainer 1 of 7

Get Unity! Get uModeler!

All our workflow explainers are waffle-free and work-tested. That’s the guarantee!

Install the Unity Hub and Unity LTS


Name of explainer: Install the Unity Hub and Unity LTS

Creative theme: Beginning 3D Modelling using UModeler

Software used (for this explainer): Unity Hub. Unity LTS

User level: BEGINNER

This is explainer 1 of 7 in this series

This series includes:

  1. Install the Unity Hub and Unity LTS
  2. Create a Unity project and install the Umodeler asset
  3. Create a UModeler object and explore the UModeler interface
  4. Navigate the scene and scale, rotate and move 3D objects
  5. Adjust faces, edges and vertices to make unique 3d shapes
  6. Create a simple car model based on the Simpsons Canyonero
  7. Apply materials and textures to the Canyonero and export the model

The Software

This series of explainers uses the Unity platform and the ‘Umodeler’ Unity asset .

UNITY is a real-time development platform. It’s a versatile development platform used for creating 2d, 3d and VR games, as their showreel demonstrates:

You’ll recognise these best-selling games, all developed in Unity. Expand to view:


Beat Saber

Arizona Sunshine

With a full 3D feature set, Unity can also be used to create animated films and cinematic sequences:

Short Movie: ADAM

Animated film: SONDER

To introduce 3d modelling we’re using the Unity 3d modelling asset UModeler:

Umodeler is a PAID asset, which retails at around £120 / $120.  Note that as of summer 2023 there is no longer a ‘free’ version available (uModeler lite offered a free ‘taster’ version with a limited feature set.  You will still find reference to it online but it is no longer available on the Unity asset store).  Once you’ve learnt the basics you may like to graduate to uModeler X, the new professional-level modelling tool for Unity:

The 3D car model created in this series

To demonstrate basic UModeler modelling tools we’ll create a simple car based on the Canyonero, as made famous in the Simpsons!  Notice it’s made from a small number of polygons, has a ‘cut out’ interior and a nice shiny coat of paint!:

If the 3d model below does not display correctly in your browser, you can see it on Sketchfab

Here’s how our Canyonero looks at the end of the initial explainers:

…and here’s how it looks after additional tweaking and accessorising:

The pre-requisities

This is a BEGINNER explainer series, but you’ll need to have a basic knowledge of using Windows, downloading and installing software to follow along. Unity is a complex application and is not recommended for new computer users. For introductory Unity courses and videos, have a look at their own learning platform, Unity Learn

Why would I do this?

We must istall Unity and UModeler to begin 3D modelling!

Let’s do it!

Click the play icon to watch this explainer video. Subtitles are available – Click the settings cog at the bottom right for options. You can watch this video full-screen by clicking the full-screen icon at the bottom right.

The main steps included in the above video:

  1. Introduction to creating a car model in Unity using UModeler, inspired by the Simpsons Canyonero.
  2. Download the Unity Hub from the Unity website.
  3. Install the current version of Unity ‘Long Term Support’ (LTS) via the Unity Hub.
  4. Create a free Unity account if you don’t have one, and sign in.
  5. Obtain a free personal license for Unity through the Unity Hub.
  6. Install the latest LTS version of Unity from the “Installs” section in Unity Hub.
  7. Prepare for the next video, where you’ll create a new Unity project and install the UModeler asset.

Good to know

As mentioned in the explainer, it’s best to select the latest version of Unity LTS to work through this series.  This ‘long term support’ version will not suddenly be updated with new or cutting-edge features, and is supported by Unity and the community, making it easier to get help and less likely your project will ‘break’ part way through.

Where to next?

In the next explainer we’ll create a brand new Unity project and import the Umodeler asset into it.
