  1. Hi there! I'm having a little problem with one of my houdini scenes, I have a fractured building, I applied some different shaders to it (like glass, concrete) however when I place an assemble node, my shaders are gone, is there any work around this problem?
  2. Hey guys, I'm pretty new to Houdini and I'm doing a train crashing through a wall. Currently I'm trying to export the animation of the crashing wall (via Alembic (~600mb/frame) to Maya Arnold to shade and render it. Viewing it in the viewport of Maya is no problem but as soon as I try to look at it in render view Maya freezes. Is there an easier way to export the crash Animation of the Wall to Maya? Or some option in Maya to make it easier? I fractured the wall with some detail with the RBD Material Fracture Node and unpacked the dopimport before I exported it to an Alembic. In the hip file is only the fractured wall for testing Thanks for the help wall_test.hipnc
  3. Hi, I am doing a personal project of iceberg destruction, and i want one of the fractured piece to behave differently like when it lands on the ground. i want them to be very small pieces like a dust. so i thought the best approach for that effect would be, make them to "grain". therefore, to get that effect, what i did was, i blast one of the piece from the simulation ,which i want them to be behave like a dust, on hitting the ground. unfortunately, i have noticed that ,since its a fractured and already has a simulation. when i apply grain source , the grain source point moves in every frame as it goes to the ground. I know point deform would fix something like that. but since i am newbie, i dont know how to fix this. I have attached a test. please have a look. if you dont understand what i said. Grain.hipnc
  4. HI I know This is a kind of basic and lazy stupid question. the question is how do you find if there is same piece number has been shared by two or more pieces ? For eg:- if you made 4 or 5 different fracture using the combination of voronoi and Boolean and you don't really know that if you named them correctly . but during the sim you noticed that some pieces are together. and you are lazy to go through all the pieces number in geo spreadsheet. what would be the easy and quick way to find two or more pieces are sharing the same piece number. ?? Like a filter or something. i usually go to the view port and press 9 and toggle to name. then i move the mouse around the pieces. but then you dont really know if some pieces are shared with some really small piece.
  5. i recently saw a reel . Some sort of abstract effect . and i just wanna know How to perfect fractured a sphere into tetrahedrons ? Is there anyone have solutions to do this ? Please help me .
  6. Hello everyone, I am trying to fracture an animated object and control the pieces with particles. I created a point at the centroid at each piece and also in the POP network created the exact same number of points to be created at the first frame. Then I tried applying those points to the pieces via "transform pieces" node but the pieces are stretching instead of following the points. Any ideas? drive_fractured_geo_with_particles.hip
  7. RBD and SOP Solver

    I am doing a RBD Fractured Solve. I want to use the Sop Solver through the Multi Solver to push and deform the objects to a final destination. I notice that when I transform the objects in the SOP Solver away from it's object center, it tends to do weird stuff. Like trying to still revolve around it's original pivot. Is there something I need to do to maintain a proper center pivot?
  8. Hi! I am new to Houdini and as a first project I am trying to make a cone + ice cream combo drop, hit the floor and shatter, while the cream melts. I have succesfully created the two effects seperately and then put them together. They interact with eachother but the FLIP fluid of the cream penetrates and leaks the cone. The strange part is if I try it with the non-fractured cone, the fluid doesnt leak (same collision settings). Help me solve why please? (The grid melter object is a small grid that transfers viscosity attribute to the particles, so that it melts faster, the closer it is to the ground.) Thanks! 001_IceCream.rar
  9. Hi Guys, I need to constraint each fractured objects to its pivot, I read on a old topic that is possible with the apply relationships node+pin constraint, but i'm having some troubles... The other method changing the state of the objects works but if I add a glue network it doesn't work anymore cuz there are 2 overrides I think. Using this expression in the constrained location inside the pin constraint works but of course it not gets the pivot of each fractured piece. dopoption(".",$OBJID,"Position","px") [/CODE] Thanks in advance.

  10. Hello all, I am quite new with Houdini, just started in the beginning of this month. I enjoy Houdini very much, however, I encounter a problem here and have been here for quite some time. So what I want to do it basically make a scene of a ball crashing a wall and then have debris coming out of the wall as the effect of the crashing and the wall being torn down. Well basically want to get this to the next level. However, I have been looking for a way to do this and found somethings but maybe because I still need to learn more about Houdini, I do not really get how to do this properly. So I thought I can start from a simpler scene first. Firstly I read a post hereand have tried to do it step by step and even try to mimic the scene exactly but I still have no luck. I use Houdini 12 so I grabbed the torus_debris_h12_fix.hip file. I did everything as exactly as how it is in the file, but as from what I check, I see that the "delete" from the particle_location1 does not work properly (If what I see is correct). Although I see this problem, I have no idea how to fix it since I think all is correct I attached my file here. can anyone help me on this? and maybe if you know a tutorial that can be helpful for me to get the hang of this? Thanks in advance houdini_29-09try.hipnc
