Today I did the stand.
The stand consists of four columns, floor and three walls. In the columns I used self-illumin with the texture of the floor with a slight modification to have lighting in the creases. In the walls and floors I used a transparent shader with the color specify of each stand.
After doing the stand I did a organization in the project eliminating all unnecessary assets (those used in the prototype and testing).
