3D Animator Teun Torenbeek, also known online as Temtor, has released a detailed step-by-step narrated tutorial for those interested in mastering basic constraints and diving into rigging and animation.
Divided into multiple chapters, this guide covers topics such as IK arms, legs, the IK/FK switch, eye rigging, and custom bone shapes, providing a default rigging setup for a 3D humanoid model. Temtor has also shared plans to focus on the animation process in his next video.
