Day 6: Today focused on the interior of the cathedral. This included the colonnade for the walkways, archways for the exterior halls, ceiling, statue, etc... With this section done the majority of the level is finished, no it's just clean up and detail work.
The water texture is tiling from above but you will not notice the tiling in-game because of the angle of view. The pattern compresses visually until it looks like the noisy motion of the ocean.
The Skydome and lighting are the next step.
