3D Cube Project

To kick our school work off, we are tasked to work with basic shapes in both Maya and Unreal Engine 4. The star of today’s project will be a simple beveled cube. We will take this primitive structure, give it a few different materials, and see if we can create something fun with it.

To start off, we need to establish scale. Using the mannequin from the Unreal Engine, we can get a good feel for our basic cube building block’s relationship to the world around it. The block we will be using for the majority of this project is roughly a 10 x 10 x 10 cm cube.

Adding a little character to this cube, we will add a bevel to its edges.

Exporting our cube from Maya we now get to play around with materials. Below you can see a few iterations of these materials when playing around in the UE4 material instance manager.

The materials for this project will combine scalable values for the block’s color, metallic expression, specularity, roughness, and emission. Seen here in the material editor, with these values established, we are able to generate multiple different instances to produce near-limitless material variations for our cubes.

Now we begin the building process. Using grid snapping to keep dimensions proportional, I began creating the base structure for my object of choice. Any guesses what it could be yet?

One side done! Time for some material assignments. After generating a few new instances, I am happy with the color palate I was able to generate. Our object should be recognizable at this point. I wanted to pay homage to the humble cube, and what better way to do that than reconstructing everyone’s favorite testing buddy: the companion cube!

A little over 5000 cubes later, and our testing companion is complete! Our cube has taken shape and is ready for a bit of atmosphere.

I threw an atmospheric fog of darkness over the world and constructed a few testing panels to place our little companion on. A simple setting, but its dark/mysterious setting fits the lore of Portal, and I wanted the focus to remain on the main cube.
