I’m curious about the PSX-era Final Fantasy games (VII, VIII, IX) and their pre-rendered backgrounds.
I understand the basics, build it in 3D, get the textures and shading rendered etc then export that out as an image. But how is this implemented in a way that the 3D characters can interact with them?
I was thinking maybe have a 2D image of the rendered scene with basic 3D shapes that are layered on top (and hidden) or maybe there’s multiple images to make up a scene?
I appreciate that unless talking to specifically someone from the development team it’s speculation but has anyone who is familiar with these games got a “fairly good idea” of what’s going on? and / or any links to articles that talk about it?
