In part 02 I have began adding base materials and some relatively uniform wall static mesh (geometry) across both the wall and floors (exc. the ceiling which will be added later). I think that the minimal textures provide an interesting subtle combination of both heavenly light casting down from above yet also a dysutopian sense of a deep abyss or void cut away from the outside world.
At the time of this capture the lighting was not built (rendered 100% accurate) which is also work mentioning. In the next part I will experiment with some internal lighting and possible atmospheric fog to added further depth since the structure is rather large and open in some areas.
