HOW CAN I CREATE A FABRIC MATERIAL USING SUBSTANCE DESIGNER?

I will show you the full process for creating a fabric material using Substance Designer. For this type of material, I selected the Physically Based (Metallic/roughness) Graph Template and deleted the Metallic output since it isn’t necessary for this particular substance.

At this point we can start to add all the required nodes from the Substance Designer library: the Fibers 1 and the Clouds 2 noises (these two are the main elements of the fabric material), the Height to Normal World Units filter (or just the Normal filter), two Levels filters, a Blend filter, a Warp filter, a Transforma­tion 2D filter, and last but not least the Gradient Map filter.

Now we can start to link these elements, starting with two Fibers 1 generators that will be placed at the beginning of the graph with the Clouds 2. The first Fibers 1 generator will be linked at the Foreground input of the Blend filter, while the second Fibers 1 generator will be linked at the Transforma­tion 2D filter, and will then be linked in the Background input of the Blend filter. At this point we have the base of the fiber of the material, but in order to make it more realistic we can add some distortion­s to the base node. To do that we have to mix the Blend filter with the Clouds 2 generator using the Warp filter.

Once done we can link this Warp filter to the two Levels filters (one will be linked to the Height output, while the second will be linked to the Roughness output). It will also be linked to the Normal filter or Height to Normal World Units (depends on the filter you prefer to use), and last but not least to the Gradient Map filter that will be linked to the Base Colour output.

Once we’ve finished linking every element of the scene we now need to set a few parameters. The first is the Y Offset of the Transforma­tion 2D filter where I set a value of 0.16, this way we can fill up the fibers of the texture. After that,

EXPERT TIP NODE SELECTION

There are different ways to add nodes and filters inside Substance Designer, the basic one is by right-clicking on an empty area of the workspace, but you can also do so by using the spacebar.

another important value is the intensity of the Warp filter where I suggest a value between 1.0 and 1.2. Last but not least we need to set the main colours of the Gradient Map, in this case I created a different one for different models, one reddish and another more yellowish, while for the Levels and Normal filters I kept the default ones, with a small variation for the Levels filter in order to decrease the roughness of the fabric.
