Buttercup engine is a quick rendering engine that has Deferred shaders along with a gausian blur. It also has some other cool rendering effects such as shadows and terrain tesselation!
OS support: macOS, macOS-arm, Linux, Windows. OpenGL 4.6 support.
Simply run the run.sh file. This works for macos with the new arm chip along with normal macos and linux. (Only tested on Mac with an m2 and linux). Windows version script is not ready at the moment.
