Assigning attributes to polygon islands using ICE
Is this feasible? I'm trying to assign random color values to points based on their connectivity i.e. fractured mesh where each chunk has a random value or color. The mesh isn't light so I'm wondering if this is going to be a slow process or if it's even possible. Cheers

It's possible indeed: http://frenchdog.wordpress.com/2010/03/21/polygon-islands-getting-the-lowest-point-index/ gray From: softimage-boun...@listproc.autodesk.com [mailto:softimage-boun...@listproc.autodesk.com] On Behalf Of Simon Van de Lagemaat Sent: Wednesday, June 06, 2012 02:13 PM To: softimage@listproc.autodesk.com Subject: Assigning attributes to polygon islands using ICE Is this feasible?

Re: Assigning attributes to polygon islands using ICE
It is an old addon and there is maybe a better way to find all those islands now (as we've got more polygon mesh attributes since 2012). If you are using it to define the islands instead of using a script, you should freeze the ICE Tree once done, as it can be very slow (it was using several repeat nodes if I remember correctly).

Re: Assigning attributes to polygon islands using ICE
I would love to know if there is another, faster way to do it now. We used your compunds on our latest project and it took almost 2 hours every time we recalculated the island attributes so we tried not to do that very often. We also did the calculation half way through the modeling process, adding chamfers and final detail after we froze the mesh, so yes, freeze is definitely your friend here. /Jens On Wed, Jun 6, 2012 at 9:52 PM, Guillaume Laforge guillaume.laforge...@gmail.com wrote: It is an old addon and there is maybe a better way to find all those islands now (as we've got more polygon mesh attributes since 2012).

Re: Assigning attributes to polygon islands using ICE
How are you fracturing the mesh? IIRC Momentum and ImplosiaFX both provide polygon island IDs. On Wed, Jun 6, 2012 at 7:12 PM, Simon Van de Lagemaat si...@theembassyvfx.com wrote: Is this feasible?

Hand modelled chunks unfortunately... it's actually stained glass pieces. I'm probably just going to create my own color texture for now due to time constraints but I would like to have a more procedural approach in the future.
