Our Journey Begins

How can we render a cube in unreal engine 5?

A simplest answer will be: let’s drag and drop a cube to the scene.

That's a great answer! Essentially, what you did was:

• Add a StaticMeshActor to the current scene
• This actor contains one instance of UStaticMeshComponent

Why is this static mesh component instance a cube instead of a sphere?

This is because we set the static mesh member variable to the cube static mesh.

Why is this cube white?

It is because we set a BasicShapeMaterial into the first element of the material array in this static mesh component.

Let’s do a summary:

Of course, to lighting our cube, we also need to put a light into the scene, let’s add a point light.
