'In memory of Ralph Eggleston-animator, director, art director, storyboard artist, writer, production designer, and our dear friend. Pixar and the world will be forever grateful,' the tweet stated.
Gutierrez shared photos of Eggleston pointing out certain frames on Inside Out, along with a heartfelt message.
'Adios Maestro Ralph Eggleston. A true titan of our art form. He reached out to me after Book of Life and I will forever cherish our conversations,' Gutierrez began.
'Before many knew he was sick he was trying to donate his spectacular art book collection to a Mexican animation school. That's Ralph,' he concluded.
