Which one of the following was NOT one of John Bray's contributions to animation?

John Bray was a significant figure in the animation industry, particularly in the early 20th century. His contributions primarily focused on efficiency and production techniques in animation, aimed at improving the overall process rather than the technological innovations seen in more modern animation traditions.

Bray is known for pioneering animation breakdowns, which involved breaking down the animation process into manageable parts, allowing for the creation of more consistent and fluid animation. He also developed the use of translucent paper backgrounds, which helped animators create layered animations more effectively. Furthermore, Bray was involved in the creation of iconic characters and worked on various successful animated shorts, but he was not responsible for creating Felix the Cat, as that character was developed by Pat Sullivan and Otto Messmer.

In contrast, motion capture technology represents a much more advanced development in the animation field that came after Bray's era, and he did not have any role in its invention. Thus, the answer correctly identifies that motion capture technology does not align with Bray's contributions to animation.
