I made them in Blender. I wanted a smooth surface, a smooth surface with connected vertices, and un smoothed surfaces. In Blender the sphere had reflectivity of 0.3. The support had a fractal noise applied for color variation. I tried different exporting functions available in the Wavefront .obj format. Only the color information was applied.
When I imported the object into T2, only one surface shader was applied. The main color information was there, and the smoothed normals of the object.
So, I have a lot to learn about object creation and importing them into T2. I was happy with the render. Looks cool. Oh, I think they could be SDI installations (?)
