In the modeling section, we will guide you through the entire process, from finding and analyzing references to creating a highly realistic wolf model in Blender. We will learn how to examine the physical characteristics of a wolf, focusing on the proportions and structures of the head, body, and limbs. Starting with sculpting the large shapes, we will progress to detailed modeling and adding texture details. Along the way, we will cover both theoretical knowledge and practical experience in topology, gradually shaping a realistic wolf model.
