"description": "The Clay SOP deforms faces and surfaces by pulling points that lie directly on them. As opposed to the Point SOP or other SOPs that manipulate control points (CVs), the Clay SOP operates on the primitive contours themselves, providing a direct, intuitive, and unconstrained way of reshaping geometry. Thus, rather than translating CVs to change the aspect of the primitive, the Clay SOP takes the inverse approach of manipulating the primitive's skin to reposition the CVs.",

For a description of transforms, see the Transform SOP. vec - The vector method provides a distance and a vector to translate along. point - The point method provides a 3D point in object space that the target point must snap to. prim - The primitive method allows the target point to be snapped to a point on another primitive. Any primitive type is allowed, including metaballs, all quadrics, and even particle systems. The point on the destination primitive is expressed parametrically as a (U, V) pair.If the Clay has a second input, then the destination primitive is going to be the first primitive in that input. If there is no second input, the primitives in the first input will snap to themselves (each face or surface to itself).",

"description": "vsharp - This parameter affects only NURBS surfaces. The pull generated by clay on these primitives can be smooth or sharp depending on the position of the target relative to the underlying domain (the farther away from a knot, the rounded the bulge) and the knot multiplicity near the target (the higher the multiplicity the sharper the pull). If the pull is too round or affects too big an area in V, the V Sharpness parameter can reduce it by inserting one or more knots at the target V value. When the V Sharpness is zero no knots are inserted. When the V Sharpness is 1, all \"degree\" knots are inserted and the surface becomes very sharp. The V Sharpness varies in discrete steps; the number of steps equals the V degree of the spline.\t\nNote: The range of the V Sharpness slider varies with the degree of the spline (i.e. the closer it is to 1, the more knots it adds). Since the number of knots added forms a discrete sequence, the slider will automatically jump to the valid positions.",
