I've created a carpet in cinema 4D and have the desired look. I've used noise to vary the look of the hairs, but when I animate the floor that the hairs are attached to, the noise seems to float over the hairs in the render. When I keep the solid that the hairs are attached to static, it works fine, but I need to give the impression the floor is moving underneath the vaccum. I've attached a video and project file. In the past, if this was happening on a regular model, I'd change the texture to UVW, but I'm unfamiliar with how the hair tag UVW coords work.
