Common mistakes when animating topology 3D models include poor edge flow (disrupting smooth deformation), too many polygons (slowing performance), and not adding loop cuts at articulation points (e.g., knees, elbows).
Poor edge flow causes unnatural stretching or tearing during movement. Excess polygons lead to lag or rendering issues. Missing loop cuts around joints means the model can’t bend realistically without distorting.
Beginners should start with a simple limb (like an arm) using basic loop cuts—this helps practice edge flow without complexity.
