Generating Roughness maps in GIMP

We will now learn to use GIMP for generating roughness maps. To do this, we will modify a texture in GIMP to turn it into a roughness map. This will allow us to easily create a roughness map for any existing texture. First, we will install GIMP and then we will quickly start creating texture maps.

GIMP can easily be substituted with other image editing programs such as Photoshop or even Paint.NET. The reason we are using GIMP is because it is completely free, and it has more advanced built-in features than other free image editors.

In the following steps, we will install GIMP and use it to create a Roughness map:
