If you use the Flip function and you still fail to mend the holes or cavities on the surface, then you might need to apply the feature in this section. Unifying the normal adjusts all the normals outward or inward so that the holes on the surface are fixed.
To unify the normals, please follow the steps below:
Select the mesh nodes that have holes on the surface.
Click the Unify button.
Before Unifying |
After Unifying |
Pease apply the Flip Face Mode feature if the problem persists.
