Creating a tileable Normal Map
Creating a Normal Map for a seamless brick wall texture is as easy as creating the Bump Map. In realtime rendering environments such as game engines these textures are very common for relief shaders of all kind. This sample file shows how you can create perfectly seamless Normal Maps for a brick texture. The same way it works for brick textures, it works for roof tiles, floor tiles, parquet or wood boards as shown with wood texture sample.
Note: Step 1 to 3 are the same as in the Bump Map example
