This is a simple hot tub that makes use of the alpha channel on its diffuse map to create transparency for the glass on the console. There are two separate diffuse maps, one that uses the alpha channel and one that does not. It also includes an opacity map that can be used for alpha instead of the diffuse maps. A metallic map is used to demonstrate that the jets are metallic objects.
This hot tub will seat up to four people and has several different areas where the jets are located. There is a jet set for each person and another set on each of the corners. Below the corner jets are the drains for the extra water. In the middle it has an area for your feet to relax in.
