If you are doing industrial product design, keyshot is the first choice, because it is much simpler to learn than C4D, and it is seamlessly connected with major engineering design software. If it is a product display, few software can be on an equal footing with keyshot in efficiency and quality. Keyshot is the mainstream renderer of industrial design companies. Whether it's keyshot or C4D, it's just for "rendering". If you have mastered the essence of rendering, then C4D. The only difference is the comfort of operation and the effect of drawing. When it comes to drawing, Keyshot is still very powerful. If it is an animation, Keyshot is far less than a 4D cinema.
