Were the shaders written in “script”? :) We had to deep dive into that runtime a reverse engineer and fix it during the fun you must have missed during the 32 to 64 bit transition we did right around Bee Movie timeline.
Nope, they were just written in C. It was object oriented C, but without a C++ compiler. Do you know the story about the whole C++ toolset that was rolled out by R&D and promptly rejected by production? That happened before my time, but according to legend is what lead to PDI’s strict avoidance of C++… until a couple of years into the DWA merger. (Clearly there were some problems beyond C vs C++, but I don’t know the whole story.) Anyway, yeah I remember starting on the 64b transition, but left before that was finished.
