I'm pretty slow when it comes to putting around ICE but I've been thinking of some hacky conceptual methods of doing it. 1. creating a particle at the center of every island, getting that particle to sample a turbulence noise and then passing that value to the island. 2. mapping only one point on the island then passing that value to the other island points. I'm sure there are better ways to do it but those are what my artist brain came up with so far. I'm not sure about what would require scripting and what wouldn't On Sat, Nov 10, 2012 at 8:39 PM, Alan Fregtman <[email protected]> wrote: Hi Ciaran, That would work for polygons individually, but Simon seems to be asking about polygon islands (so multiple polys per island.) That's quite tricky to get via ICE alone without scripted help.
