Both looking convincing, very nice. And thanks for the hint doing it with ICE. I will give it a try.

Create a simple animation(sphere cutted by a box, animated as a cycle) do a flipbook over a few hundred frames and watch the memory consumption. Even a 'Delete All' command or creating a new scene does not flush the memory. The Implosia booleans (tested with 2015) don't have these issues btw. Nor the built in booleans in XSI 2011. How about a google doc or something like that, where we can add bugs and issues left in XSI for future reference? Just a thought.

Remember to triangulate your geo before doing complex booleans - it will be a lot more stable. Other than that, I know it might not help you, but the new boolean engine in Houdini 16 looks amazing: http://www.sidefx.com/docs/houdini/nodes/sop/boolean Also Maya has lately gotten a couple of boolean plugins that look promising, although I have no idea about stability: http://www.hard-mesh.com/ http://lesterbanks.com/2017/08/new-live-boolean-plugin-maya/ //Morten > Den 29. august 2017 klokken 13:09 skrev wavo <[email protected]>: > > > Hello, > > you can also try Implosia > http://www.si-community.com/community/viewtopic.php?f=5 > <http://www.si-community.com/community/viewtopic.php?f=5&t=6373&hilit=m> > &t=6373&hilit=m > omentum its now free, You can create booleans via Icetree or > sricptedOp vie the PulldownMenu > > > > Am 8/28/2017 um 11:28 PM schrieb Sven Constable: > > > > ,, > > > > > Hi list, > > > > I had several projects lately that involved animated booleans with > > CAD data, which is problematic sometimes.
