Creeping and Blending
There are a variety of methods to control Sasquatch fur. The simplest is to apply it uniformly over your entire object. Sasquatch lets you paint or texture map the density. You can also restrict the fur by surface. In the picture below on the left, the surfaces of the chessboard squares determine which type of fur is added.
An advanced feature of Sasquatch lets you advance or withdraw the fur from a surface boundary. This is very useful when making fur that needs to cross a border, but it's awkward to remodel or resurface your object. Bordering fur patches can also use a soft transition to smoothly blend neighboring fur patches together. The middle picture above shows how the fur is "creeped back" from the surface boundaries. The right picture shows how the dark fur has advanced past its boundaries, and blends smoothly with the light fur. This kind of control is valuable to make organic blends seamlessly.
In the example below, you can see how Sasquatch solves a common problem. The picture on the left shows a wolf nose. Notice that the fur properly stops at the boundary of the nose itself, but this leaves an ugly seam and ruins the photoreal effect. The right hand image shows Sasquatch's easy solution. With just a minor tweak, you can creep the fur just a little bit past the boundary and soften the edge so the density fades out over a few millimeters. This kind of problem could also be solved with an image map, but the creeping control gives you extra versatility and works even in difficult-to-map places like inside an ear.
Sasquatch allows any number of layers of fur, even on top of one another. The image to the right shows a short, tight layer of fuzz with a sparse second layer of long, loose fibers.
