With the second part of the lighting project, we built upon the same scene from before and added more lights as well as an IBL (image based lighting.) We had a new reference to match and it took a bit more effort to match this one because of the variety of new light attributes and the high render settings towards the end really slowed down the renders. There is also a concept we learned that is a lot to take in. It is called Linear Workflow and I would like to give it its own post because it is really important and really interesting.
The biggest challenge in this project was the grain I was getting in the render as well as the slight muddiness that is visible around the top of the door frame. Bumping up the render settings only took it so far, I decided to cap off the settings when the render times became well over 10 min. (a frame!)
Some new lights I learned about from this project was portal light and physical light, which are mental ray lights that accept information from the IBL. This allows for some very quick realistic lighting that has the potential to look really nice if the IBL is good enough.
From this project I learned a lot about how maya treats lighting and how they are rendered through mental ray. I was surprised by how interesting and deep lighting can be and how I can further improve other projects with it. See you soon.
