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

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!

A blue 3D mug model with "pixels.cool" text is displayed in the Tinkercad design interface.

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!

Colorful mugs with "retro cafe" text are stacked on a counter in front of a neon "Retro Cafe" sign in a stylish, modern café setting. — Colorful mugs with “retro cafe” text are stacked on a counter in front of a neon “Retro Cafe” sign in a stylish, modern café setting.

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 offers a complete toolkit to assemble a 3D scene from scratch. This could be for a video, animation or a game level / environment. You can even export a Unity scene to a VR headset if you like!

In this explainer we’ll create a Unity project then import the 3D mug created in Tinkercad, the Space Invader built in Kenney Shape and the spaceship exported from Kenney Shape.

Good to know

Unity is a realtime 3D development environment. It’s FREE to install and use for new users – You only start paying if you want to make money from your creations 🙂

This explainer is appropriate for INTERMEDIATE users. The UNITY LEARN platform offers free and paid courses and tutorials to help bring your skills up to scratch:

As seen in this video explainer, we recommend using the latest version of ‘Unity LTS’. LTS is short for ‘long term support’, making it ideal for newbies and classroom / educational use. You can use the latest beta version to enjoy Unity’s cutting edge 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!
