# Troubleshooting normal maps
## 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](https://discord.com/channels/717692382849663036/1039320529255026829/1041478803584733276) 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](https://www.photopea.com/).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://wiki.redmodding.org/cyberpunk-2077-modding/modding-guides/textures-and-luts/self-made-normal-maps/troubleshooting-normal-maps.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
