Is it possible to turn fantasy novel into a 3D animation? About how much material will it cost?

It's a good idea, and it's entirely possible,

But there is a problem. You must learn all kinds of software based on 3Dmax, as well as animation, and you must make it move. If it is only a simple action, it can work in software. But believe me, if it's you alone, it's a little pitted. You have a team of more than 20 people, and this team needs a clear division of labor, such as modeling, sculpture, topology and mapping. These are just technical aspects.

It is simple. If you want a big scene like Final Fantasy, that's great. Infrared camera, studio, martial arts action guidance, special effects teacher, hey! Dude, if it's just you, forget it. The investment needs at least10 million RMB.

If it is a hit novel, I suggest finding a reliable partner, provided that the commercial value of the novel is higher than the input.
