Could you imagine if Disney decided to open source one of their 3D films? How much fun would that be to play with?

It would be like when Doom was open sourced (I pick Doom because it's one of the first major video games that I can remember being open sourced, and the creative results have been vast)

I'd like to see Toy Story 1 re-rendered using the Toy Story 4 models (assuming Disney also made those available). Imagine all the technical challenges you'd face to do that: Write code to convert the models, sets, skeletons, animations. Upscale/create new textures, etc.
