This chapter explores having a 2D character and a 3D character interacting with one another. We examine the most important method of eliciting an emotional response from the audience, which is by including touch in our characters. The characters must touch both each other and themselves. The issues that need to be resolved are registration, timing, and line look. How do we make characters drawn in different media look like they are touching and make the line quality of the characters look like they match?
