  1. Packed rbds and friction

    Hello everyone, I'm doing a simple packed RBD sim, and no matter how much I increase the fritcion parameters the objects never lose any velocity. Is this the expected behaviour? I've attached the .hip file. test.hip
  2. I'm having different results in my simulations using packed rbds connected only to a bullet solver vs when using a POP source to emit the rbd packed object into a popsolver/bulletsolver multisolver. The bulletsolver alone is giving me the expected results... I've seen some tutorials and tips by artists that recommend the multisolver approach, because it allows control of the RBD sim using pop forces and wrangles, and thats why I'm asking this. bullet_solver.mp4 rbd_multisolver.mp4
  3. QWidget window resizing

    I'll follow that advice.
  4. QWidget window resizing

    I created a widget in qtdesigner following this tutorial: https://github.com/kiryha/Houdini/wiki/python-for-artists . So far I've tried all layout constraints and align methods within qtdesigner but houdini doesn't recognize them. This results in a window that looks like intended but doesn't resize... Any one knows how to solve this?
  5. I'm developing some UI for pipeline tools. One of the tools is an HDAs and Setups manager, where I click on the desired HDA and it is imported into the current geo context. I spent some time reading the documentation and other created threads on how to get the current geo context path and all I've managed to do is a workaround where I have to select one or more nodes and only then can I import my HDA into the selected context. Any ideas on how to achieve this without having to select any nodes?
  6. Optmizing popwrangle

    It is faster indeed, no idea why... How can I use the grp variable I created to set the particle group in the way you showed?
  7. Hello Houdini Magicians, This little bit of code is, according to the performance monitor and some debugging, slowing down my simulation... alot. Specially with a high number of particles. The nPt comes from the nearpoint function. I analyzed the performance impact of the nearpoint function with many particles and it is not significant. Its the conditions and moving/removing particles from groups. What is the optimal way to do this?
  8. Quaternion rotations

    This has lots of info ! Your the best ! I will jump in right away ! Cheers
  9. Trying to find some info on applying quaternion rotations without using the copytopoints @orient point attribute. I build my quaternion, and then I'm stuck on doing two things: -Applying the rotation to an unpacked object and a packed object I've tried the rotate by quaternion VOP with unpacked geo and the makeinstancexform for packed geo and nothing seems to work this way... I've done some research but didn't find anything usefull (outside of copytopoints @orient). Can some one point me in the right direction?
  10. Karma for particle rendering ?

    That is nice, though I find it hard to get any decent volumetric look when rendering with pathtracing :\
  11. Karma for particle rendering ?

    @schwungsau try rendering 1 billion particles with pathtracing
  12. How can I render my particles with the isotropic volume lighting model and get self shadows? Its like there is no occlusion and I can see my particle field from one way to the other side, and I can't distinguish wich are in front and wich are in the back... Cheers, Diogo
  13. Are there any good resources on rendering particles with Karma? And does it support micropolygon rendering? Thanks
  14. Hello fellow magicians, I'm trying to better understand gasequalizevolume DOP inside FLIP Fluids and so far I haven't found anything usefull outside of the Houdini documentation and example files. So I tried to create a simple example file to test it out. So far, I can't seem to create one of the necessary fields for gasequalizevolume to properly work, the goal field. I used a gasmatchfield DOP and imported a pre-created fog vdb with the name goal, and nothing happened. To debug I setup a multifieldvisualization DOP and set the density field to goal, but it doesn't display anything... If some one could have a look at the file and point what I'm doing wrong... Also, if you any information or tutorials on this subject I'd be very gratefull! Thank you Gas_Equalize_Volume_RnD.hip EDIT: The Gasequalizevolume was wired in the wrong input. It needs to be wired into the volume velocity. Still can't get the gasmatchfield to work though...
  15. Vellum Shelf Tool

    When I create a shelf tool containing a vellum solver node, all the nodes within the solver disappear once I try to use the tool. The same does not happen when I create a tool that has a normal dopnetwork.
