newbee Posted January 16, 2017 Share Posted January 16, 2017 (edited) I am trying to use gasimpacttoattributes to create some hit impulse attribute for flip but it seems like it doesn't work because i have no impact data.. does anyone know how to generate impact data and get hitimpulse to work for flip? the only thread i found online was https://www.sidefx.com/forum/topic/37420/?page=1#post-170605 here is a simple scene file to test hitimpulse.hipnc if you check the spreadsheet u can see that the hitimpulse is 0 Edited January 16, 2017 by newbee Quote Link to comment Share on other sites More sharing options...
newbee Posted January 16, 2017 Author Share Posted January 16, 2017 (edited) ok i got it.. I used a "gasintegrator" to solve this issue.. here is a quick way to create impact data and there by create hit impulse for flip hitimpulse_and_impact_data_solved.hipnc Edited January 16, 2017 by newbee 2 Quote Link to comment Share on other sites More sharing options...
Atom Posted January 16, 2017 Share Posted January 16, 2017 Thanks for the setup I always wondered how to generate impact data with FLIP. So what does the impulse value represent? Is it speed on impact? Also, do you know what the value of the flags represent? I mainly see a 0 and a 4. 1 Quote Link to comment Share on other sites More sharing options...
newbee Posted January 16, 2017 Author Share Posted January 16, 2017 (edited) hitimpulse records strength of collision. The values of hitimpulse depends on the force with which flip impacts the collider I put together a quick test and noticed that: if you increase flip incoming velocity and hit the collision object with more force the hitimpulse will have a higher range Edited January 17, 2017 by newbee Quote Link to comment Share on other sites More sharing options...
