 +====== Spline Displacement (Node) ======
 +
  
 This node evaluates the distance to a point on a spline and outputs a displacement to that closest point. This node evaluates the distance to a point on a spline and outputs a displacement to that closest point.
 +
 +The accuracy of this node relies on the number of Evaluation Steps defined in the [[tools:s-tk:primitive|]] or the [[tools:s-tk:prefs|]].

 These two define the minimum and maximum range for the displacement. Anything at or below the minimum will be 100% displaced, anything at or beyond the maximum will not be displaced at all. These two define the minimum and maximum range for the displacement.

-This is the strength of the displacement, as a value from 0 to 1, and takes the Function input into account as well. It's almost identical to the normalised output in the [[tools:s-tk:proximity-node|]]. +This is the strength of the displacement and may be negative as well, pushing away from the spline.
-This can be used like a weight to, for example, drive the positioning of instances.+

 +The node connected to the function input is applied to the blending strength between the original position and the displaced position. This allows you to shape/modify the falloff.
