Пересчитать нормали в Blender 4.1

In this video, I provide a comprehensive guide on how to check normals in Blender. I explain the impact of incorrect normals on a 3D model, including issues with modifiers, modelling, and shading. I cover three main methods to check normals: using the face orientation option in overlays to identify flipped normals, enabling vertex, edge, and face normals in mesh edit mode overlays for detailed inspection, and using backface culling to visualize normals in a way that simulates game engine environments. I conclude the video by demonstrating recalculating normals for a single mesh to ensure they are correctly oriented.
