Hey Rob, do you need a compound for building the description? I might have a plugin for you...

Pretty sure there was a compound once, if not you might try Mr. LaForge's Convex Hull<http://frenchdog.wordpress.com/2012/01/05/happy-2012/> ICE node.

Polygoniser takes the nulls but gives blobs rather then a single mesh! Thanks for looking though!

ICE topo should be able to do this, :) but not sure how you are to build the polygon description from a set of random positions!? not so easy what kind of mesh are you after? if its not just a regular clean topology then you could simply put all nulls into a group and use the global.kini.pointpositions to feed into a polygoniser mesh. hth On 5 September 2012 09:17, Lawrence Pankhurst <[email protected]<mailto:[email protected]>> wrote: Hi guys, I thought I remembered a nulls2mesh script knocking about, can't find it anywhere! I've got a set of nulls and want to turn them into a mesh, ie position of each null becomes a vertex in said mesh! So anyone now where the script is or is there an ICE tool? Had a look on http://rray.de/xsi/ but couldn't see what I was after! Any help appreciated. Cheers Lawrence -- - Ciaran
