Let a primitive attribute (name) survive polygon to vdb to polygon

[anicg]

After voronoi fracture, each piece has a name and can be coloured differently based on the name (color node, random from attribute: name).

After the vdb, and vdb convert to polygon, the name is still there but not for every piece, it’s one name one colour for the whole thing, all the pieces get the same colour.

how do i “smuggle” the name attribute through vdb and still get it after i convert vdb to polygon?

When you convert multiple primitives to a VDB the VDB is a single primitive, hence you're only getting one name in the process.  

You need to do this conversion inside a for loop(by name) to ensure the correct name is copied to each piece.

You don't necessarily need a loop, although it might be the cleanest (and if compilable) fastest way.

Anyway, here is a file to show 2 other methods of doing it
