bwatts Posted July 19, 2015 Share Posted July 19, 2015 Hi Guys, Wondering if someone could help me out here. Say I have a standard box fractured (packed) with Voronoi and I sim that with no forces in play, as expected the pieces stay together and are perfectly aligned, no impacts, no moving away - GREAT! When I glue them in the same situation, then delete the constraints either in sops (animated) or with a sop solver connected to the constraint network, impacts are detected and start moving the pieces apart, Grrr. Not sure why this happens, there's nothing that has changed. Test file attached. Any help would be GREAT! glue.hipnc Quote Link to comment Share on other sites More sharing options...
Diego A Grimaldi Posted July 21, 2015 Share Posted July 21, 2015 Seems to work fine for me! What version of H r u using? Perhaps a bug Quote Link to comment Share on other sites More sharing options...

So when you're deleting the glue over time the pieces don't move?? I'm using H 335, will update just in case. Quote Link to comment Share on other sites More sharing options...
Diego A Grimaldi Posted July 21, 2015 Share Posted July 21, 2015 yea, nothing is happening deleting the glue..it stays still as it should... I tried in H13.0.665 and H14.0.368 Quote Link to comment Share on other sites More sharing options...
bwatts Posted July 21, 2015 Author Share Posted July 21, 2015 (edited) Ok man, thanks for checking it out. I'm installing 14 395 right now, gonna check & let you know Edited July 21, 2015 by bwatts Quote Link to comment Share on other sites More sharing options...
bwatts Posted July 21, 2015 Author Share Posted July 21, 2015 yea, nothing is happening deleting the glue..it stays still as it should... I tried in H13.0.665 and H14.0.368 Ok so when I play the file I attached, after frame 15 impacts show up in the geo spreadsheet then pieces start to move apart. How on earth is this not happening for you! ...So frustrating Quote Link to comment Share on other sites More sharing options...
iamyog Posted July 21, 2015 Share Posted July 21, 2015 (edited) I tested on H14.0.355 In both case, deleted_animated or delete_static, when the constraints are removed the pieces spread out. It's much subtle in the case of static though. By turning on the "Use Parallel constraint solver" toggle on the bullet solver, both simulation remains still for me Edited July 21, 2015 by iamyog Quote Link to comment Share on other sites More sharing options...
Diego A Grimaldi Posted July 21, 2015 Share Posted July 21, 2015 Nope...you can even see on my screen Quote Link to comment Share on other sites More sharing options...

I'm also seeing the pieces staying in place now thanks to "Use Parallel" and NO impacts are detected which is what I expected to begin with. Thanks so much!

bwatts Posted July 21, 2015 Author Share Posted July 21, 2015 (edited) Nope...you can even see on my screen Hey Diego, it's bizarre that Anthony (above) and myself are getting this behavior but you're not, his suggestion is definitely working by the look of it. Still not quite the behavior I expected without "Use Parallel constraint solver" turned on. BTW if you're ever speaking to Craig Tonks, say Hi for me Edited July 22, 2015 by bwatts Quote Link to comment Share on other sites More sharing options...
Diego A Grimaldi Posted July 21, 2015 Share Posted July 21, 2015 Yea, not sure...Craig is in London, I'm in Vancouver Quote Link to comment Share on other sites More sharing options...
bwatts Posted July 22, 2015 Author Share Posted July 22, 2015 Yea, not sure...Craig is in London, I'm in Vancouver Thanks for your help Diego, the more pieces I have fractured, things start screwing up even with "Parallel Cons" turned on. I'll continue to try & figure this out. Quote Link to comment Share on other sites More sharing options...
