In the production of "TORSO VISITOR" animation, the goal is to give priority to visual effects, improve the quality of all aspects of animation, in the script, role scene design, model carving, role performance, post-production layer level control, and strive to achieve the highest animation efficiency, the best effect. The team attaches great importance to the creation of the script, the drama conflict, the complex drama relationship, the film's audio-visual language skills, the scheduling of the lens, into the production of 3D animation. The large-scale use of unreal engine in production technology has improved the production efficiency of animation. The modeling mapping process of the next-generation game is used on the material mapping to perfectly match the unreal engine, thus improving the efficiency of model making again. The action uses open source motion capture database or directly uses motion capture technology. The particle function of the houdini is then assisted to enhance the overall picture texture of the animation, finally the most efficient finished animation. The 3D animated short film "TORSO VISITOR" tells the adventure story of the interstellar exploration team in its mission. The film is more than 5 minutes long (the beginning and end of the film) and nearly 100 film shots.
