Troubleshooting normal maps

In-game, your normal map isn't looking as expected

Import settings

The texture has to be imported without the isGamma flag. Import over an already-existing normal map to rule out this as a source of error. See this conversation on Discord for more detail.

UV scaling

Cyberpunk actually considers the UV map's scaling when calculating the weight of the normal maps:

the problem

Since the neck part is scaled much larger than the chest, this will make the parts of the mesh visibly distinct.

The solution

Inverted shading, especially in the up/down direction

If you have a normal map you've already baked and want to fix, simply invert the green layer in Photoshop/photopea.
