The Attribute Transfer is nice to prototype an idea, but it's rather slow (unless they rebuild it since I used it) compared to the execution speed of a Vop Sop. In Vop Sop, I use the PcOpen + Pc Filter to mimic the Attribute Transfer at God speed :)
While we're speaking of the xyz+PrimUV, I found it has a weird behaviour compared to the ClosestLocation of ice. Here's a screen shot of what I have : https://drive.google.com/open?id=0B1QqhXD7Y15qU3BKY0ZmdktNSWc Basicaly a Grid emit some particles with a Pop solver, I build a PopVop to create a Velocity(v) that make the particles going from their position toward the closest UV location on the Sphere. If you look at the screenshot you can see that the location has some preferences for the points and edges rather than the polygons area. Have I missed something ?
