Customizing Normals - 9: How Tangent Normal Mapping works

I will attempt to explain how Tangent Normal Mapping works in common terms and with plenty of visual examples. Normal mapping is one of the most powerful tools we have for achieving high quality custom normals. But it is difficult to use because it requires complete understanding to get it to do what we want. And it is hard to find a good explanation in terms artists will understand. So I shall attempt to make the explanation I wish I'd had when I was learning it! This video will attempt to explain how it all works. It will be mostly theory. The next video will be the practical application. Topics: What Object Normals maps are What Tangent Normal maps are What a Tangent is What a UV tangent is and why we need them Creating Normal Maps without using the Bake system Making a custom Normal Mapping group that allows arbitrary Normals How to compute UV Tangents in Geometry Nodes Blog posts for this series.
