This is explainer 7 of 8 in this series

This series includes:

  1. Get tooled up for this explainer series
  2. Navigate the Tinkercad interface, add 3d objects to the workplane and rotate & scale them
  3. Create a coffee mug in Tinkercad
  4. Export a coffee mug from Tinkercad in OBJ format
  5. Navigate the Kenney Shape interface and edit built-in objects
  6. ‘Trace’ a Space Invader image in Kenney Shape to create a 3d object and export it in OBJ format
  7. Create a new Unity project and import the objects created in Tinkercad and Kenney Shape
  8. Import a free Unity coffee shop asset and place our 3D objects in the scene

The Software

This series of explainers uses three separate programs:

Tinkercad for introducing basic 3d navigation, scaling and rotating shapes, combining them and exporting 3d objects. Tinkercad is completely free and runs in a web browser. Get yourself a free account now!

Kenney Shape, for ‘tracing’ a 2d image to turn it into a 3d object and export it. At time of writing Kenney Shape costs less than £5 / $5. We created and exported a 3d Space Invader in explainers 5 and 6.

Unity for importing 3d objects and assembling them into a scene. Unity is FREE for personal use. We’re starting to assemble our Retro Cafe in this explainer and the next!

3D Objects created in this series

Using a general theme of ‘Objects for a Retro Cafe’, we’ve already created and exported a coffee mug using Tinkercad:

We’ve also ‘traced’ a 2d image of a Space Invader in Kenney Shape to turn it into a 3d object, which we’ll import into Unity in this explainer:

Here’s how your 3d cafe scene could look at the end of this series!

The pre-requisities

This is a BEGINNER explainer series, starting with beginner-friendly software. You need to have a basic knowledge of using Windows and downloading and installing software to follow this series. Tinkercad and Kenney Shape are beginner-friendly programs. Unity is a complex application and is not recommended for new computing users. For introductory courses and videos for Unity, check out Unity Learn

Why would I do this?

Unity lets us build a 3D scene from scratch. This could be for the purpose of creating a video, animation or game environment. You can even export a scene to a VR headset if you like! For help exporting from Unity to VR, see our introduction to VR explainer series.

In this explainer we’ll create a new Unity project and import the mug created in Tinkercad, the Space Invader created in Kenney Shape and the spaceship created in Kenney Shape.

Good to know

Unity is a sophisticated realtime 3D development environment, and is FREE to use (until you start publishing your creations and making money!). If you’re interested in a step-by-step guide to installing Unity, we covered the basics in our Virtual Reality explainer series.

This explainer is appropriate for INTERMEDIATE users as beginners with 3D software may need additional help. The UNITY LEARN platform offers free and paid courses and tutorials to help you bring your skills up to scratch.

As seen in this explainer, we recommend using the latest version of ‘Unity LTS’. LTS is short for ‘long term support’, making it ideal for classroom / education use. You can use the latest beta build to enjoy Unity’s newest features but you may run into unexpected issues and errors.

Where to next?

In the next (and final) explainer in this series we’ll import a FREE coffee shop asset into our Unity scene and place our retro objects appropriately!
