Tip: How to use images to manipulate fur
Whenever you’re mapping images to surfaces, the best way to control them is by creating a UV map
Whenever you’re mapping images to surfaces, the best way to control them is by creating a UV map.
First, unwrap your model using a UV tool, in this example we’ve used Luxology’s modo app, but you can use another 3D application of your choice.
Now it’s time to add the fur. First, select the polygons in the viewport that you want to apply fur to, then press [M] to apply a new material.
Name the material and click OK. In the Shader Tree, find your new material and add a Fur Material by selecting Add Layer > Special > Fur Material.
You will see a guide hair appear in the viewport if you have done this correctly. By default, modo uses the Material’s Diffuse Color value to shade the fur.
Whatever colour you select will be transferred to the fur strands, so go ahead and choose your colour in the Diffuse Color selection box.
If you press [F8] for a preview, you’ll see fur appearing through parts of the model you may not have wanted.
If you’re using my example scene, you’ll see hair through the patches on the chest and feet.
To fix this, you’ll paint a density map. Start by selecting Add Layer > Image Map > New Image. In the pop-up, name your file and choose JPG. In the next window, select 2048×2048 and RGB, tick the Set Color box and choose white in the colour picker, then click OK.
