Shading and Lighting in Modo are necessary functions. Lighting plays an important role in illuminating the scene and setting the mood. Shading defines the look of the modeled surfaces as either shiny or dull, reflective or transparent and rendering calculates the combination of the two to produce the final image. The following topics provide information on applying materials, using the Shader Tree and working with layers. Setting up the environment, lighting and volumes is also covered in this chapter, as well as an overview of the baking workflow. Click on the topics below to be directed to the appropriate topic page.
