+====== Spline Proximity (node) ======
 This node computes the distance of the current point/shading spot to the closest point on the selected spline.
-{{:tools:s-tk:pasted:20190819-155100.png}}
+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|]].
 ===== Controls =====
 ==== Spline ====
+Selects the spline used by this node.
 ==== World Coordinates ====
+Switches all evaluation to world coordinates.
 ==== Minimum Distance ====
 ==== Maximum Distance ====
+These two define the minimum and maximum range for the normalised outputs. The output will ne 0 at the minimum range and 1.0 at the maximum range.
 ==== 2D Evaluation Axis ====
+The 2D evaluation axis used by all 2D outputs.
 ===== Nodal Inputs =====
 ==== Position (vector) ====

 ===== Nodal Outputs =====
 ==== Distance (scalar) ====
+The distance of the current point to the closest point on the spline.
 ==== Normalised (scalar) ====
+The distance of the current point to the closest point on the spline but normalised into a 0..1 range using the Minimum and Maximum Distance.
 ==== Position (vector)====
+The position of the closest point on the spline.
 ==== Direction (vector)====
+The direction from the current point to the closest point on the spline, normalised.
