promote via wrangle

[Follyx]

how could I promote a point attribute via wrangle into a primattribute?

[Atom]

Drop down an attribute wrangle that runs over primitives.

Fetch the value using the point function and assign it to a new attribute.

f@my_promoted_attrib = point(0,"my_point_attrib",0);

You may notice the problem with this, however. I am fetching the attribute from point zero. So to do it right, you would have to loop over all the points for a given primitive and then average them to produce a single result.

It just make more sense to use the provided attributePromote node.

from a point wrangler you can do this :

Quote

setprimattrib(0, "promoted_prim_attribute_name", @primnum, v@point_attribute, "set");

Instead of "set", you can also put:
add,min, minimum,max, maximum,mult, multiply,toggle,append.
