The rug in our scene is created from a chamfer box with the bottom half deleted. This allows a slight curvature to the rug itself. The rug also has fifty segments in both the length and width.
Option 1: VRayDisplacementMod
The first technique uses the VRayDisplacement modifier on the rug mesh itself. I used the 3ds Max Cellular map to drive displacement. The only adjustment to the Cellular map was the size, set to 0.001.
In this example, the settings in the modifier are the default settings except for turning Keep continuity on. You should note that the Amount of displacement ranges from 0″–2″ and increasing the displacement gives very different results. While this is a quick and effective solution for camera angles that are not close to the rug, the detail in the rug breaks down when you look at the close-ups.
Additionally, you will see that as the displacement amount increases, the control on the fur direction is limited with straight strands of fur. You could probably get away with using a vector map to control bending in the strands themselves, but again, this depends on how close the camera is to the mesh.
