  1. Control velocity with color

    speedResistace_dl.hipnc
  2. Emit pyro outwards (not upwards)

    curve_smoke_outwards_dl.hipnc
  3. Control velocity with color

    Multiply your velocity by luminance(@Cd)
  4. Question about Ocean Spectrum

    oceanwaves_towards_center_dl.hipnc
  5. Fetch SOP parameter

    By using the ch() VEX function(https://www.sidefx.com/docs/houdini/vex/functions/ch.html) or the Channel VOP.
  6. Polyextrude - transform extruded front - by attribute

    If you want uniform scaling, you need to use the "insetscale" attribute. Local variables or per-primitive/edge expressions are not supported for performance reasons. https://www.sidefx.com/docs/houdini/nodes/sop/polyextrude#notes
  7. pyro spread activation question.

    Forget my first setup. I did it really quick and didn't really pay attention to the way I added the temperature from the sphere. While it works for the effect shown in the tutorial, it might cause issues if you happen to make a pyro sim out of it. And it's also slower. pyrosourcespread_anim_temp_dl_v02.hipnc
  8. pyro spread activation question.

    pyrosourcespread_anim_temp_dl.hipnc I color coded the nodes of interest red.
  9. You can absolutely use pre-fractured geometry. https://www.sidefx.com/docs/houdini/examples/nodes/sop/rbdconnectedfaces/RBDConnectedFaces.html
  10. FLIP Inverted Deforming Collision Object Problem

    As long as you don't need both liquids to interact with each other, it's probably easier to just do two separate simulations. One with the inverted SDF and one without.
  11. While I haven't done something like that personally, because it seems really inconvenient having to resim the wedge you liked, it should be straightforward. Just remove any reference to the current wedge in the simulation ROPs save path(but not for the preview generation obviously) and it should overwrite your sim data. EDIT: Or you could use the Remove File TOP to delete the sim data after the preview generation is finished.
  12. Joy of Vex 7 coding issue

    The reason it doesn't look like in the GIF is because you connected your grid with "pointwrangle2" to your second input of "pointwrangle3". Connect your scattered points to the second input of "pointwrangle3" and you'll see that the VEX code does what it's supposed to do.
  13. Houdini 19 Wishlist

    Versions being split between Apprentice(non-commercial), Indie, Core and FX is not counter productive and does make sense if you look at it from a financial standpoint. If you just need a version of Houdini to mess around with and practice, the free Apprentice version is perfect. If you work at a small studio or a freelancer who doesn't earn more than $100k a year, the more affordable Indie version is for you. If you don't need to be able to modify or create DOPs but do anything else, Houdini Core, which costs only half of what a FX license does, gets the job done. If you need everything Houdini has to offer, in a mid-sized/large studio, only then you need to reach deep into your wallet and get the full FX license which costs around $5k+ without the annual upgrade plan. Imagine every artist would have to buy a full FX license regardless of what they actually do in Houdini or how much they earn. Sounds like a sure way to lose a sizable chunk of paying customers and in turn get more pirates.
  14. Walk down the tree

    PageUp or PageDown to go up and down. , or . to go left and right on nodes that are connected to the same input/output.
  15. Screenshots of the node tree are not helpful because people can't see the parameter values you used. This gif should illustrate how a voronoi diagram works and how to avoid small pieces.
