If you get the Volume attribute from the instance master group, you'll have an array of values. Select a value from the array using the same integer that you used as the Index to select a shape from the group, and save it as a custom attribute on emission.
BTW CollisionSize doesn't work because it's one of those "reserved" attributes. ICE knows what to do with it if it exists, but it doesn't actually exist until it's been set. gray From: softimage-boun...@listproc.autodesk.com [mailto:softimage-boun...@listproc.autodesk.com] On Behalf Of Adam Sale Sent: Tuesday, February 18, 2014 10:55 PM To: softimage@listproc.autodesk.com Subject: Setting a particles mass based on its instance size Evening again everyone, I'm looking for an attribute that lets me read in each particles instance size / scale, so I can use it to drive per point mass. I am using Momentum deform bodies and wanted to drive my mass based on the chunk size. Not sure if this would be the same situation for regular instances. I wasn't sure how to look up instance size, or calculate it. Anyone have any ideas on how to go about this? My first thought was to read collision size, but it returns an error. I don't see any other handy ICE attribute I could leverage. Thanks for any thoughts Adam
