This week we worked more on the shaders of our object. Everyone is using a Stanford model for the object, I chose the Buddha. My rock is more translucent so I’ve been focusing on adjusting the subsurface of the object. I also created a ramp for the subsurface color to try to replicate the varying color in my stone. I added a good amount of values within my ramp to get it looking just right and then added some noise and changed the noise frequency so the ramp wasn’t just plain strips and looked more organic.
I also worked on creating a few different layers this week like my shadow and occlusion layer. I create a shadow mask layer in maya and then put the occlusion inside that layer. I not only have the Buddha in my scene but a white ball is in the scene as well.
I’ve also been working on the different layers I want for my render. I’m using AOVs for the layers dealing with my shader, like subsurface and specular. Both of those aspects are split into their direct and indirect to give more control in the composite.
