The best thing about this product it's that you can use any render engine to work with guerila, even if its not open source or free like say gimp/blender etc., I have used other products in my time but they were very difficult at times when using them as an artist because there was no way around having your own computer setup just so i could get things done efficiently without all these problems. And also sometimes their tutorials are hard to understand which makes learning how everything works harder than necessaryAlso some features such as custom shaders aren't easily found elsewhere (such as those from blender). If anyone wants something easy then go somewhere else otherwise do yourself a favour by getting one! It has helped me create realistic looking renders faster compared to others out here who donno what real world looks really mean lol.
