This gave us great flexibility if we needed a different material or look in certain areas or if we needed to add cracks or stains in specific places.”īesides artistic flexibility in the design of the layered floor shader, the initial motivation was much more optimized render times: the factory shaders that ship with RenderMan for Maya offer great flexibility on their own, but when many layers were combined (which were needed for the complex floors), the render times shot through the roof. With this shader we were able to stack and 'layer' our textures one on top of the other similar to the layering system in Photoshop. The images below are examples of our custom, multi-purpose, layered shader, that was used to create the look of our Mexican Cantina floor. These shaders gave us tremendous power and flexibility in giving us the specific look we desired. To achieve this look we incorporated custom shaders into our workflow created by Christos Obretenov of LollipopShaders. Not only did they have to look good from an artistic standpoint, they had to hold up to the extreme close ups due to the scale of our characters. “In the production of Sausage Party the floors and ground were major focal points of the film.
