100% procedural material in following formats:
Fur Lenght/Shorteners, Curliness, Colors can be adjusted in Substance Painter.
Here is a [short video](https://youtu.be/cxbaxaKH2SM) on YouTube about texturing with this material in Substance Painter.
I found that the best way to create the fur in Substance Painter with this material is:
Drag Fur_material.sbsar to Substance Painter shelf, define it as a base material, choose whether you want to import it to the current session, your project or shelf, and click Import.
Add a layer to your project
Select the projection tool (shortcut 3) and drag the Fur_material to the Material mode button to switch to the material mode.
In Channels mapping menu choose height as a mask instead of no alpha
Begin to paint the fur on your model of an animal or whatever model else with the Projection tool. Use S+Left mouse button to rotate the stencil, S+Right to zoom, and S+Middle to pan.
I used the Basic soft brush with No pressure size control.
You can also just create a fill layer with Tri-planar or UV-projection.
