  1. RBD concave thin wall collisions not detected

    hey joe! i unpacked the geo, cleaned up attributes (left P N uv), laid a normal sop and exported an alembic. I am rendering in Cinema4d with octane and it seems that the normals are freaking out in most places coinciding with the fractured edges. i had this before as i said and i was not able to solve it my problem looks a little like this https://www.sidefx.com/forum/topic/52105/?page=1#post-234574
  2. RBD concave thin wall collisions not detected

    I am having another little issue and I remember that the only other time I shattered something in houdini, i stumbled into the same thing. I exported an alembic, but upon rendering it seems that normals are jittery on some of the pieces.ld Should I maybe lay down a facet instead of normal, cusp and post compute normals? Might that help?

    will do cause honestly the sim is a little jittery and not all collisions are perfect maybe i'll try this method next time. thanks!
  4. RBD concave thin wall collisions not detected

    hey julien, i kinda solved it... i got a little confused along the way, but tidied up things in the end ended up getting rid of convex decompositions for both collider and rbd object. used concave representation for both and reduced collision padding and split impulse threshold by a lot. of course now it's super slow and the result isn't super stable, however it will work for what i need. thanks guys for the help !
  5. RBD concave thin wall collisions not detected

    thanks! will do now.
  6. RBD concave thin wall collisions not detected

    i am using packed prims now, but still not working correctly. still trying to figure it out.
  7. RBD concave thin wall collisions not detected

    thanks julien! now the collider is excluded, however the pieces collisions are not working properly. trying to figure this out alession odforce_01.hiplc
  8. RBD concave thin wall collisions not detected

    julien, i think i am getting there now i need to exclude the collider (which is now a packed object) from the activation pop wrangle, but i really can't think of how. girl_fracture_07_convex_decomposition.hiplc
  9. RBD concave thin wall collisions not detected

    it's just the collision representation of the inner volume got it. i'll try to do that now!
  10. RBD concave thin wall collisions not detected

    i had a look at your setup and certain things definitely make sense, even for a newbie like me! thank you! however, collisions are still not working and the pieces fall straight through the collision volume. trying to figure it out!
  11. RBD concave thin wall collisions not detected

    Thank you so much Gonna dive in now and see if I learn something. Will let you know!
  12. RBD concave thin wall collisions not detected

    Hey Julien, I have been implementing convex decomposition (probably the wrong way), and made a bit of a progress. Would you mind having a look at my file? Assets .abc is included. https://www.dropbox.com/s/eaheclpww2w090l/FRACTURE.zip?dl=0 thank you
  13. RBD concave thin wall collisions not detected

    Hey Julien, I am gonna give that a shot and report back. thank you
  14. hey guys i am having a little bit of an issue with this test. i picked up this setup from another thread on this forum however in this particular scenario it doesn't seem to work as i am probably missing something. basically the pieces getting activated and falling, do not collide with the inner shrunk body volume i created and - since i am a houdini newbie - i am struggling to figure this out tried to change geometry representation to concave, tried to increase resolution of colliders, but nothing worked so far. i'd be really grateful if anyone could suggest a possible solution. here's HIP and assets in case you want to have a look. https://www.dropbox.com/s/eush4f5hus2uhwy/fracturing%20animated.zip?dl=0 thank you in advance.
  15. Thank you so much!!!!!! That's silly and really screams #newbie
