Using Point/prim Variables To Alter Sop Attributes

[aracid]

hey all

If i use

point ("../attribcreate1", $PT, "smoothVal", 0) ---> on the smoothVal point variable

or

prim ("../attribcreate1", $PR, "smoothVal", 0) ---> on the smoothVal prim variable

within something like a point sop or an extrude sop (i suppose there are many more sops)

it produces predictable results (ie, extrudes the primitive based on the imbeded attribute)

HOWever

if i use that on a smooth sop(placing this expression under smoothing iterations), it doesnt work

why is that ?

and does anyone have an idea on how to achieve smoothing an object based off variables imbedded in the object ?

thanks in advance

brian

Not all sops read point and/or prim attributes. Smooth sop is one of those. One way to vary smoothing across an mesh is to smooth it all and then blend it with an unsmoothed version using a vex sop driven by your smoothval attribute.
