This operator takes a handle generated by the Meta-Loop Start operator and will import attributes from the current metaball. A success code is returned if the attribute is imported correctly. There are three special attribute names:
1) "meta:density" - The density of the current metaball at the position specified (float) 2) "meta:transform" - The local transform on the current metaball (matrix) position specified. 3) "meta:prim" - The primitive number of the current metaball (int)
This example demostrates how to use the Meta-Loop Start, Meta-Loop Next and Meta-Loop Import VOPs.
It calculates the sum of the densities of all metaballs in some input geometry, and uses that total to create an image in a Composite Network.
The following examples include this node.
