To draw and publish an imaginary novel character, one needed to obtain the authorization of the novel. Without the permission of the copyright owner, no individual or organization may distribute, copy, publish, or publish this novel in any form. In many countries, including China, the copyright law has stipulated the duration and management of the copyright of a work. The protection period of most works is usually the author's lifetime and a certain period after his death. The specific period depends on the type of work and the identity of the author. Transforming a work into a three-dimensional character model and posting it on the Internet without the permission of the copyright owner may violate the copyright of the work. Therefore, if you want to convert an imaginary novel character into a 3D model and publish it on the Internet, you must first obtain permission from the copyright owner. If you are not sure if you can obtain authorization, please contact the copyright owner and ask related questions.
