We've been playing with the graph for weeks now and we're really impressed! Except for these things: Lit Output don't work; nothing happens on screen and shader errors are thrown in the console Some naming could be better or more searchable, like Tex Index. Why not use texture which would make both "Tex" and "Texture" work in search? Lack of tooltips make it quite a trial and error process to create VFXs The first one is our biggest blocker. Lit particles are essential to realistic looking games and animations.
