Work In Progress
This week, final adjustments in Maya are settled. This is a version with less shadow noise. In order to cast a harder shadow, I applied a spot light with its target on my model. And for its direction, I followed the shadow of the rock on ground.
Due to limited time, the rendering of other pipes on walls and other machine outdoor was skipped. As the lighting setting for outdoor area was different, I thought I d like to render in a different render output, to gain better result. However, it was predicted to spend a few more working days on it. As the submission deadline is coming, I finally decided to skip it.

Then I have to do the roto and color matching in Nuke.
