If you are into polygon Island ID, this is a must have : http://julianjohnsonsblog.blogspot.fr/2013/07/faster-polygon-islands.html Fast as hell !

Re: SimulatedFrameFraction on polymesh ?
Hey Peter ! Thank's a lot ! You're totally right ! I Will try something like this. I'm doing some fast R&D, moving from one kind of "test" to another (now I'm on something else). Playing a lot wit PolygonIslandID. Slow to generate, but super handy ! I might come back to you again with questions ;) Thank you again !

Re: SimulatedFrameFraction on polymesh ?
I may be totally wrong but isn’t ‘SimulatedFrameFaction’ the amount of time for each simulation step – so time divided by steps. I believe I have come across this SimulatedFrameFaction inside one of the factory compounds, but which one? the first ones that come to mind are ‘state’ and ‘simulate particles or rigid bodies’ or perhaps ‘bounce’. or wasn’t there a simulation root with integrated states? as a hack you can just create it I’d go for a scalar value of 1 and save it as self.SimulatedFrameFaction (per cloud not per particle I’d say) and see if this helps? that said – you might not really need a state machine! you can get a lot done by just adding an integer value as per particle data and using conditions based on this data. get data > self.mystate > if = 1 > execute ... (I hope that’s not too cryptic?) the ‘case’ node is particularly useful for this – plug self.mystate (integer number) into condition and add as many case inputs as states you want – and plug execute nodes in there. think of each execute node as a hub for all you want to do with a particular state – set data (set color to see what’s happening!), add forces, filter,... anything really. changing states is as simple as setting self.mystate to some other number and next step it’s done. The cool thing is that this plays nice with your regular simulation, while the state machine can interfere and change behavior (perhaps precisely because of this simulated frame faction) I imagine you have islands in your mesh that have to switch between paper and cloth based on some condition? that approach should work fine for that. (if the ‘simulate mesh’ can work on a designated part of the mesh – I don’t know if it does) From: Olivier Jeannel Sent: Tuesday, March 22, 2016 4:35 PM To: softimage@listproc.autodesk.com Subject: SimulatedFrameFraction on polymesh ?
