reassigning material every draw call to allow for meshes with the same shader to have different materials

Updated skybox to shader to make the rendering relative to the camera position, meaning you are allways in the right position relative to the world

Added cursorlocking to the view, infinite movementgit add .git add .! (alt tab or esc to exit the mode)

Added skybox sample, reverted use of packed UV coords, now we use 32 bit instead of 16, ie. both axes use 16 bit precicion
