VSFX 319 - Project 2 - Marbles
The main references I used for my marbles are the first 3, but altered the colors of the second 2. The green blended in too much to the grass, so I made it pink/orange with an OSL gradient. Then on the striped one, I also changed the colors and left out the piece on the inside.
For the grass model, I used xgen and exported it as geometry that I could then manipulate in Maya. The front grass pieces I subdivided more and extruded to add more details to the shader such as slight subsurface.
In the hypershade, I worked on creating masks from OSL shaders for different shader properties as well as mixing and blending them with existing noise and texture nodes in Maya. I was able to preview what each node did by using base color on an AiFlat Test material.

While working near the end of my project on adding scratches to my front marble, my maya project crashed and corrupted , causing me to lose a few hours of work since I hadn't saved a new version. You can see in the screenshot below how everything turned green (all shaders deleted) and the concrete geometry disappeared as well.
With the project as a whole, I struggled with visualizing and understanding what each OSL shader was supposed to do. In project 1, I started to rely on seeing the textures mixed together in the hypershade preview the way I would in Nuke. Because of this, it made it hard for me to work without being able to see the texture previews with OSL. To get around this, I previewed the OSL shaders with an aiFlat by plugging them into base color. Even with this, though, I sometimes struggled to understand what the parameters in the OSL shaders meant or they seemed to behave randomly.
For this project, I kept the compositing pretty simple because I was happy with how most of the render turned out. Therefore, I just added some depth of field, subtle color grading, vignette, chromatic aberration, and comped the sky into the background so it wasn't warped like the HDRI sky was.
Here's a before and after for comp!
