In this section, I’ll show you how to add some details to normal map with adobe photoshop and Quixel.
Open the normal map in Photoshop. Add new layer and paint white. Change the layer mode to Darken. Select blush tool with black colour. Drew some circle and go to Filter > 3D > Generate Normal Map.

This photoshop filter is nice and easy but lack of functions for advanced texturemaking. The Quixel give us the solution. Quixel NDO is the photoshop plugin for creating normal map. Restart photoshop and open the normal map from cinema4d. Lounch Quixel SUITE and hit ‘N’ button.
Select Background layer (= the normal map) and click ‘Normal to NDO’.
So, preparation is ready. Hit the Add new sculpt layer.
Select blush tool and draw something. this time, The line you drew changes directly. Also easy to adjust the normal map with NDO’s parameters. If finish tweaking, hit ‘Toggle zip mode’. I add more details with other layers.
The result in Unity is below. You can create nomal maps without 3D tools. No modeling, sclupting. Just 2d painting!
