  1. UI Dialog Help

    Hi Michael, I had the same problem as you and I ended up using pyside2, but you might want to check out alex's huilib in this thread. His wrapper comes with an example script and it seems to work in 16, and seems great for simple ui's cheers Craig
  2. RE-timing nuclear pyro sim help

    qLib works fine with pyro. You need a velocity field and you need to animate the frame parameter at the top of the node.
  3. RE-timing nuclear pyro sim help

    you should check out qLib(just search qLib for houdini) .. the volume retime ql did a great job for me of retiming without changing the look of the sim and with no strobing.
  4. dynamically adding constraints in dops(SOLVED)

    Can remove the constraint transform in the sop solver and just add a rest position before out geo in the sop net
  5. hi I am adding constraints to objects that are created in sops, then taken into dops and I am having problems getting my constraints to line up like they do on the first frame. It looks like some kind of motion offset but whatever it is I cant seem to solve it. help would be greatly appreciated. thanks. Craig add_constraints_001.hip
  6. non voronoi more realistic fracturing.

    Actually volume breaker in TP uses voronoi to fracture. You can use "cells"(particle clouds) to activate and place your fracture, scale in xy and z and joint pieces together but its still just a voronoi pattern. (maybe has some dispacement or a nosie mod post sim), The biggest difference for me between houdini and TP rbd sim's is the speed. TP is much faster but I have used TP alot more than I have houdini so it could just be me .
  7. replacing areas of velocity in a flip fluid

    I think I have got what i wanted using a sop solver as i couldnt get the gas field vop to work . I did it the same way ikarus suggested but i used a mix and clamped the bias instead of a 2 way . I would still be interested to know what would make gas field vop work. thanks Craig

  10. replacing areas of velocity in a flip fluid

    I am a bit confused how I should wire this up and how do i get volume field "newvel" into the gas vop. I am wiring the gas field vop directly into the 3rd input of the flipsolver .Also I only need to bring vel in as a parameter and use vel as the output. sorry for dumb questions but its been a while(years) since I had time to dive back into houdini.
  11. replacing areas of velocity in a flip fluid

    thanks ikarus, i'll give it a try.
  12. replacing areas of velocity in a flip fluid

    I am trying to make a flip fluid follow a volume field without replacing the whole containers velocity. I basically want the fluid to stick/follow the object if the volume density is 1 and as the density gets lower gravity and other forces take over. I've tried to use source volume and gas linear combination but forces only seem to work when velocity is added which makes them move to fast. Set to copy the fluids move at the correct speed but forces don't have any influence. If anyone has any ideas or samples it would be much appreciated. thanks Craig
  13. VRay/etc tutorials

    in my opinion vray is so easy to get nice results (and now mr too) because of two things its energy conserving shaders and its tonempper .... and mr now has these features now thanks to zap andersons mia_material and mia_exposure lens shader
