Do not run save files from other users. In the slim case that anyone is still using this or comes across this repo, only load save files from the included Tutorial / saves folder and from sources you COMPLETELY trust.
I made this repo when I had no idea what I was doing, and save files perform raw object deserialization. Save files are therefore a trivial vector for viruses. Yeah, who's gonna get a virus from this obscure project, but I don't wanna mess up anyone's day by accident and I have no idea who is watching :3
Prima is a very old, very broken, very insecure suite of software tools for generating animated images. The library follows a "node-based" approach to rendering, much like many shader libraries, but is designed for creating visually interesting images, rather than textures for 3D rendering.
