The production process for 3D animations typically involves several stages, including pre-production, production, and post-production. In the pre-production stage, a 3D animation service will discuss the project requirements with the client, create a storyboard, and design the animation. In the production stage, the animation team will create 3D models and animations for those models, and in post-production, the animation will be edited, sound and special effects will be added, and final tweaks will be made before delivery. The length of time for the production process depends on the complexity and length of the animation.
