logix1390 Posted March 3, 2020 Share Posted March 3, 2020 Hello, I am trying to do something pretty simple using the new h18 sop level bullet solver.. I want to merge in two different Glue constraints, each with a different data name ("Glue" "and "Glue_Two"). Then I want to break each unique glue constraint on a specific frame. It seems as if I technically got it working, but for some reason my constraints are not maintaining its strength. I have them both set to -1 which means it should never break until told to do so. I feel like I am not setting up the data names on the bullet solver properly... I will attach my file for anyone that wants to take a look. Thank you. rbdBullet_constraints.hipnc Quote Link to comment Share on other sites More sharing options...
Noobini Posted March 3, 2020 Share Posted March 3, 2020 here's a simpler to digest scene, the Torus is set to break at frame 24, the Pig is set to break frame 48 vu_BreakDiffConstraints.hiplc Quote Link to comment Share on other sites More sharing options...
Noobini Posted March 3, 2020 Share Posted March 3, 2020 and here's your file that's been modded. I find it a bit flaky tho...like if you change the 2nd break to some other time from 48...sometimes it works, sometimes it doesn't...even with Reset Sim everytime that is. vu_rbdBullet_constraints.hipnc Quote Link to comment Share on other sites More sharing options...
Noobini Posted March 3, 2020 Share Posted March 3, 2020 (edited) ohh....man this is a real noice gotcha..... say you adjusted the scene above, to break the 2nd wall at frame72, it does jack $hit... go into Advanced>Bullet Solver>Sleeping Time, increase that to 5 say....works !!! Alternatively, leave Sleeping Time at 2, increase Contact Breaking Threshold....works too....what's the correct way ? I have NFI.

logix1390 Posted March 4, 2020 Author Share Posted March 4, 2020 @Noobini Thank you for the response. Yeah that is very weird how it doesn't work when you change the frame number . Your tips worked . I will need to do more testing myself. . I was confused about merging in multiple constraints with different data names... but apparently if I am using multiple glue constraints, you can only use 1 data name and use the grouping options to control them separately.

Noobini Posted March 4, 2020 Share Posted March 4, 2020 think there's something about Mary...err...I mean Glue...explicitly "Glue" Quote Link to comment Share on other sites More sharing options...
