  1. H16; POP is missing attribute.

    Hi, You didn't have any particles emitting, so you couln't see any attributes. To see your particles attibutes, put a null after your Popnetwork. Here is your seen. disintegration_v.2_modif.hip
  2. Hi there, I'm trying to build an particle asset to use in C4D. I want the particles to get the velocity of my object. It's working fine in Houdini, but when I import the asset in C4D, the particles are emitted on the object even it's moving, but it's not computing the velocity. Is anyone know if it can be done ? Thanks, Charles
  3. I succed to scale my objects in unabling "rest" in the Deformation tab of the solid object. It seem to lose it's softness but I'l try to mess around with the settings.
  4. Thanks, it's working ! So now I have another problem. I want to control the POSITION and the SCALE of my objects. So far, I succed to attract them, but I don't know how could I scale them. I would like them to be really small at the begining and big at the end of the animation. Thanks again Sean Charles Multiple_object_FEM.hipnc
  5. Hi, I would like to use FEM (or soft body) on multiple objects. Basically, I used the copy SOP to copy objects on points. If I use the FEM after the copy SOP, they are merged together. The sollution was probably on this post but the link doesn't work anymore : Thanks, Charles
  6. Houdini Help example files?

    Hi, I'm sorry if my question is stupid but I don't see how to remove the preferences folder. Thanks
  7. Soft spheres FEM in copy SOP

    Thanks for your help man !!! I finally succeed to do it ! One of my main problems what the "solidembed" nod and and the fact that some spheres where intersecting before the tetrahedralize. The "tetrasurface" was useful to smooth the mesh. Thanks again Anthony spheres_FEM.hipnc
  8. Soft spheres FEM in copy SOP

    Hi, I would like to recreate the exemple I posted below with the squeezed spheres. I duplicated spheres with a copy Sop but I can't figure out how to apply properly the Fem. I used the piece attribute but it's not working as I expect. Someone as an idea ? Thanks Charles spheres_FEM.hipnc
  9. I'm really interessted about this as well. I'm trying to use FiniteElement with copy sop or Particles, but I can't find the right set up. I really hop that someone will answer !
  10. Hi, I'm trying to create an effect where the fractured pieces of a geometry get transform into spheres, then collide with each others. I want the elements to be soft. Then I want them to fly away. I tried to use FEM fractured solid object, but I couln't set it properly. Should I use Organic Tissu in my For Each loop or looking for another solution ? Thanks fracture_to_spheres.hip
  11. Hi, SteveNi I don't know if it's the best solution but it work like that. vector pPos = attrib(1, "point", "P", 0); int maxpoints = 1; float dist = 0.2; int pnt_near[] = nearpoints(0, pPos,dist, maxpoints); printf("%s \n", pnt_near); Charles
  12. compare attributes in VEX

    Thanks heaps Moritz !!! I tried something similar, but couldn't find the proper syntax. Thanks again Charles
  13. compare attributes in VEX

    Hi, I'm a newbie in Houdini and vex, with basic knoledge of programming. I want to create vertex between points from 2 different objects, using vex. The look will be the Plexus style with the difference that I don't want the points to connect from each other when they are from the same geometry. I followed a tutorial from Entagma to help me. The question is : How do I get and compare an attribute from 2 points ? I tried to use pointattrib() to compare an attribute "myobj" that I created before but I don't have enought kwnolege yet to use it well. //__ List of the closest points int pnt_near[] = nearpoints(0, @P,dist, maxpoints); foreach(int pnt; pnt_near){ //__ condition if pnt and @ptnum do not share the same value of the attribute myobj if(pointattrib(0, myobj, pnt, 0) != pointattrib(0, myobj, @ptnum, 0) { int myprim = addprim(0,"polyline"); addvertex(0, myprim, pnt); addvertex(0, myprim, @ptnum); } } I don't know if it's the best way, so I'll be happy to hear any solution from you. Thanks, Charles plexus_attribute.hip
