The next step was to take that X1E0X10X10 and bevel the edges. Then to import that cube into UE4 and use the cube to make a simple scene with materials and lighting.
When I first started coming up with a scene I thought it might be cool to make some kind of cave with a crystal in the center. Then I remembered that salt can naturally form in square crystals and I thought that would be a perfect fit for the beveled cube.
So I started making the center piece first, and I figured out how to make the material transparent, but when I did that I lost some of the materials edits and I couldn't make the crystal glow. So I came up with this idea to put glowing cubes on the inside.
