This is a common problem with smooth-shaded, low-polygon-count models. It is caused by mismatching of the true shape of the polygonal model and the smoothed normals. Here are three solutions:<br> **1. Soften the lighting.** Increasing the size of the light will: ✔ Preserve the polygon count.<br> ✔ Preserve the shader realism.<br> ✖ Alter the look of the render.<br><br> **2. Adjust the shadow termination.** (Blender 2.9+) Adjusting the shadow termination offset will: ✔ Preserve the polygon count.<br> ✖ Alter the shader realism.<br> ✔ Preserve the look of the render.<br><br> **3. Subdivide the geometry.** Subdividing the geometry will: ✖ Alter the polygon count.<br> ✔ Preserve the shader realism.<br> ✔ Preserve the look of the render.
