Question

Graphic arts

Hello fellow toasters. Maybe someone will tell you what our cartoons are drawn on, animated: Ivan Tsarevich and the Gray Wolf, How to catch a bird's fire feather, Three heroes on distant shores.
Thank you in advance.
I ask that now I am persistently engaged in drawing on a tablet in the SAI program, there is a goal to reach the level of a character artist for cartoons of this style, I like it very much.

Answer 1

Maybe you should ask the question directly to the developers melnitsa.com/#/faq

Answer 2

Tracing paper, pencil, scanner, photoshop, maya (3D), I don't know about 2D animation.
But it's better to find out on what the "Illusionist" was created.

Answer 3

It is interesting, but having the experience of drawing ONLY in Paint Tool SAI, is it possible to create something for games, cartoons or get a job in the game industry, etc.
