edheng Posted January 3, 2011 Share Posted January 3, 2011 Ok, so I got the FBX file and it is a building that is supposed to collide and fracture, however, the cracks show but there is no debris or what not, am I doing something wrong? Thanks Quote Link to comment Share on other sites More sharing options...
Macha Posted January 3, 2011 Share Posted January 3, 2011 You have dopnet or a popnet in your scene? or The FBX is animated and loaded in as such? Quote Link to comment Share on other sites More sharing options...
edheng Posted January 4, 2011 Author Share Posted January 4, 2011 yeah I do have a dopnet in my scene but the FBX is not pre-animated, all it is doing is falling to gravity and colliding. Quote Link to comment Share on other sites More sharing options...
Macha Posted January 4, 2011 Share Posted January 4, 2011 Could you send us the file, or a simplified version of it? The forces could be to weak, or something with the sdf, or they stick together, or are broken but fall at the same speed, etc. Quote Link to comment Share on other sites More sharing options...
edheng Posted January 4, 2011 Author Share Posted January 4, 2011 ok, turns out when I turned the cut plane offset up from the default of 0 to 0.001 the things start to split from the cuts in the geometry, could that be the reason though?

Macha Posted January 4, 2011 Share Posted January 4, 2011 Possibly. If you use the original settings and change various substeps settings in the solver, perhaps also the penetration passes, does that solve it as well? Quote Link to comment Share on other sites More sharing options...
edheng Posted January 6, 2011 Author Share Posted January 6, 2011 changing the substeps worked a bit, still the fractures are too big, and the penetration pass just kills the CPU so due to the restraints it cannot be done. Also another question that popped out, if I were to give the geometry an interior, would I require a closed obj? Quote Link to comment Share on other sites More sharing options...
