Minding my own business working on an asset when I encountered an issue and here we are with a tutorial. Most of it is part of old Polycount but some fresh take.

Full version here:

Its 2025 we have nanite, AI, lots of procedural tools and fancy features yet I keep seeing students, artists looking for answers on how to get nice normal maps for curved surfaces. Well this should give some clarity and a bonus tip, how to keep the volume and shape of your high poly in zbrush intact when using the SubD+Morph Target trick.

Note: If making low poly from high poly then skip the bonus tip. Its for situations when dealing with CAD or making high poly from low poly.

To further improve understanding on normal maps I would highly recommend Polycount.com wiki pages and this thread:
