How to Fix 99% of Your Normals INSIDE UE5 (3 Methods)

In this video, I’ll show you how I fix 99% of my normals using the following 3 methods: Two-Sided Material, Flip All, and Flip Manually. I know it doesn’t cover 100% of the cases, and sometimes you do need to export the mesh and fix it in the dedicated program. But in most cases, it’s unnecessary as Epic Games continues to develop the In-House Modeling Mode
Enjoy!

Very cool video! Not messed with Unreals' Modeling Tools yet. Very handy!

Thank you :)

Is there a way to unify normals that have somehow been broken on a per-face or vertex level? As in, not flipped, just split so that some verts have more normals than they should? I can do that in Maya, Max, Blender, etc. but is there a native Unreal fix?

I am not aware if there is any way to do this for specific faces or vertexes, but you can recalculate normals for the whole mesh. Under Modelling/Attributes/Normals - there is Normals Topology. You can choose for split normal method "Face Normal" and play around with the Threshold.
If you need to do this only for a part of the mesh - you could detach this part with "Separate" under Mesh/Tri Select/Separate, apply new normals and then reattach it with "Merge" under XForm.
Let me know if this helps!
