How To Check Your Normals In Blender

I demonstrate this by showing two versions of Suzanne the monkey, highlighting the issues caused by flipped normals. I explain that incorrect normals can affect modifiers, modelling, and shading, making it crucial to get them right.

First, I show how to check normals using the face orientation option in the overlays menu, which visually indicates normals facing away by colouring them red. Then, I move into edit mode to demonstrate another method using vertex, edge, and face normals, although this method can be cluttered and less useful for complex models.

I also explain how backface culling can help visualize normals in a way that resembles game engines, though it may not be ideal for more intricate models. Finally, I demonstrate how to recalculate normals by selecting the entire mesh and using the “recalculate outside” option, resulting in a properly rendered model.

I hope this video helps you understand how to manage normals in Blender effectively.
