  1. i created a custom attribute($DEPTH) and i tried to map it to color using a color Sop and it does not work. however when i used a point sop it works. why can i access the $DEPTH attr using a color sop when i can using a point sop. ( see file )
  2. Flip and Sop Solver

    I have been experimenting with FLIP and at a point where i want to use a sop solver to manipulate the velocity of the particles.. so, I create a sop solver in the AutoDopNetwork and then.... inside the SOP solver are > dop_geometry, impacts, feedbacks, relationship_geometry i want to grab the dop_geometry and to "process" but i am thrown for a loop with the `stamps("..","DATANAME",chs("../datapath"))` can anyone help me with this magic ? While i am happy Houdini autoMagically fills in the data, i am clueless what is imported? If i were to delete all the nodes inside the SOP solver, how would i bring the Flip particles in, to process them to change their velocity. thanks in advance

    thanks Spencer !
  4. Mantra error

    I am new to houdini and every time I create a new mantra node and try to render I get an error Failed GLMakecurrent with error 6 handle is invalid What am I doing wrong? Have a camera and light in my scene. Creating a new mantra node throws the same error Any help appreciated

  6. cloth constraint input values

    i have a simple example of a cloth being constraint to a torus. i have to be doing something wrong because if i edit the remesh ( to make a high res mesh ) the constraints go crazy ( because the vertices are hardcoded - un-houdini like. ) i guess i am doing something wrong.. ? in the file, try changing the remesh to .5 from 1 and see for yourself. cloth.hipnc
  7. cloth constraint input values

    ah ! i got fooled when i did not see a pull down menu with group names like some other operators. thanks for your help !
  8. creating an RBD trail ( not debris)

    HI All: I have a simple scene with a rbd sphere with initial velocity i would like to create new spheres at each frame , ( almost like a trail of spheres, I would like them to be RBD with activate set to off, so they are frozen ) I am lost and dont know how to proceed, any tip would be appreciated. thanks trail.hipnc
  9. creating an RBD trail ( not debris)

    thanks for the tip. good to know another way to achieve the same effect. followup question ( did not want to create yet another thread ) i have a group node ( with an animated bounding box over a bunch of points ) as the source to a pop network . the setup works fine except when there zero elements in the group node.... the particles are created at the origin when i expect there to be no particles because there is no source... here is file group.hipnc
  10. creating an RBD trail ( not debris)

    thanks a bunch tomas! trying to play with motion blur but using shaders on actual geometry....
  11. Hi all I need to divide some points based on a pscale attribute. 1) less than .3 , pscale =0 2) 0<pscale<.6, pscale =.6 3)else pscale =1.0 I tried to use 3 point nodes with expressions. First one is easy. if ($PSCALE<.3),0, $PSCALE. But how do you do compound expressions .like 0<pscale<.6 or Pscale<.6 and pscale >0 Another workaround was to use a group node and delete nodes for each case. But it not elegant Thanks in advance
  12. Editing Glue network in 13

    I am a little confused, just stated learning houdini and jumped onto houdini 13 and i am stumped how to edit a glue network. the network itself is different from houdini 12.5 and i would like to edit the network but am stumped.i would like to partially dissolve the glue network in this test file. any help/suggestion is much appreciated glue_network_v2_glue.hipnc
  13. Editing Glue network in 13

    thanks cwhite for your file..your file does not open properly for me, i get error opening the file. i am using h13.0.198.21 there was an error message about unknown 'pivot' do i need to known load another version of h13 ?thank you
  14. just started learning houdini and sorry if its a stupid question. i am trying to shatter a simple object using my own network (instead of the shelf button) and i do not know how or where to continue. i have an example file, where i have shattered and have a "network" ready to be wired-in, but i am lost. any / all help much appreciated. explode_glue.hipnc
