4 In the Channel Box, rename the Duckling fur description to TeddyBear.
Observe the yellow spikes that have appeared on the model. This is the
fur feedback - a rough approximation of how the fur will appear when
rendered.
Fur feedback shows various fur attributes such as color, density, length,
direction, and scraggle. By looking at the fur feedback you can
immediately see how the changes you make to the fur attributes affect
the appearance of the fur, without having to render the scene.
The fur feedback on the legs, arms, and top of the head of the model
appears different in comparison to how it appears on the body and snout
surfaces. It should appear consistently on all of the assigned surfaces,
which indicates that the surface normals may not be oriented consistently
for all of the assigned surfaces.
Reversing surface normals
When you apply a fur description to a surface, each hair making up the fur
description points in a direction normal (perpendicular) to the surface by
default. This direction is called the surface normal. When the fur does not
display consistently on a model it may indicate that the surface normals are
oriented inconsistently.
Dolly the camera so you can view inside the arm.
