Hey I was on the PDI side as well, ahoy, nice to see you here! I had forgotten about Shark Tale using RenderMan, but I will say to the degree there was competition and to the degree that PDI won any pipeline battles, DWA eventually won the war. :P ;) There was plenty of cooperation as well, it just takes time for two companies to integrate, and plenty of people on both sides were quite attached to the cool tools they made. (I was certainly guilty!)

PDI’s toolset was pure magic for it’s time. When I joined, I was in heaven with how easy it was to make procedural animation, build new effects that crossed pipeline stages, render anything you could imagine… I wished I could share it with researchers and hobbyists.
