 ===== Normal Maps =====
+Using normal maps is quite easy. You can find example textures everywhere and many graphic tools like Photoshop or GIMP are able to build them.
+They have a blueish-greenish look, like this example:
+{{:0.8.4:brick-n.jpg?nolink|400}}
+__WARNING:__ Because Gorilla3D is using OpenGL you have to be careful with the source. NormalMaps are different between OpenGL and DirectX.
+In a naive way they are flipped. But the result can be very different.
+__NOTICE:__ We do only support normal maps for OpenGL. In case you have a DirectX normal map in your texture set, you need to convert it yourself.
+For conversion have a closer look at this article: [[https://help.ambientcg.com/02-Using%20the%20assets/Normal_map_styles.html#:~:text=Editing%20the%20map%20itself,color%20channel%20and%20invert%20it.]]
