Cel Shading in Blender

1. The video covers several techniques for achieving a cel-shaded look in Blender, including using the compositor, Shader to RGB node, and various material setups. Compare and contrast at least three of these methods, discussing their strengths, weaknesses, and the specific situations in which each would be most appropriate.

2. Explore the use of image textures in controlling the colors and shading of a cel-shaded material. Describe a scenario where using a custom-designed image texture would be advantageous over procedural methods, and explain the steps involved in creating and applying such a texture.

3. The video demonstrates several methods for creating outlines, including the inverted hull method and grease pencil. Design an experiment to compare the performance and visual quality of these two methods on a complex animated scene. What metrics would you use to evaluate their effectiveness?
