Attribute Blur SOP

Overview

This sop lets you blur attributes using a radius over which to do the blurring.

Usage

Use it to blur any attribute on a surface. Only blurs one attribute at a time.
If there is a normal "N" attribute on the input then only attributes attached to points that face in the same direction will summed during the blur.

Parameters

Group	The group of points to effect
Geometry with attribute	Full path to the geometry with the attribute on it. The path should be to a sop with the same number of points. By default the expression returns the input sop, which is generally what you would want.
Attribute to blur	The name of the attribute to blur.
Local Variable	Optionally add a local variable mapping to the choosen attribute.
Type	Float or 3-Floats (vector style).
Blur radius	The distance over which to do the blurring. Larger number mean more blur. The size of this value is relative to the geometry size.
Max # of points within radius	How many points to concider within the radius when doing the blur. 1000 is usually enough but with very dense geometry or very large radius values this might need to go higher. Higher numbers may well take longer to cook and you might easily get away with lower numbers.
Normalise	If the attribute is a 3-float vector then this option lets you normalise the resulting blurred value.
