  1. How to Stop Jittering Particles

    sometimes it happens if you use jitter in the source. Try uniform distribution of points
  2. Hey Jim, I hope that's what you need. 3d_dash.hiplc
  3. Volume density from texture?

    Hello, here is some of my attempts to do something similar. But I can't get a similar level of detalization in mantra. If somebody can suggest some tips it wound be amazing volume is still a little bit blurry, I guess it could be because of texture resolution vol-0001_volume_v01.hip
  4. Deform Groom curve stretching

    Hey Ray, I had the same problem actually. I had wire simulation and collision with vdb. Didn't solve it really, but if you'll try to use 'ray intersect' as a collision method increase substeps check scene scale and all parameters. it could work
  5. Accurated mix colors in Flip

    Hey I asked about similar effect some time ego and I've reached result but not really what I need hope it will help, and someone will answer
  6. FLIP Divergence Question

    Hey, just did some tests and everything works fine for me 1. you need to initialize a `divergence field` attribute (for example in attribute wrangle @divergence = 10;) 2. you need to turn on a "add divergence filed" parm in the flip object 3. in the flipsolver - divergence. the divergence by attribute parm must be turned on as well
  7. volume noise follow particles

    not really clear without a scene file you can pass vel attribute to the noise amplitude and add fit node to control it
  8. Advecting Pyro with Object (Help)

    Hey Cristina, slightly complicated scene for an example Also, skull geo will be helpful. You can lock any geo in the scene through a node's flag or a new cool 'stash' node you don't need the static solver in the dop anymore in the static object turn off object transform and make "obj path" parameter empty a static object has an ability to grab vel from collision object, probably you don't need source volume turbulence 100 is tooooo much you don't have a temperature so buoyancy is useless
  9. Houdini 17 Wishlist

    I've chosen some good in my opinion. Almost all in Ben's first message @LaidlawFX Make it full Qt app. @Stalkerx777 more OpenCL support and nice Nuke-like value editing from @marty And As @Thomas Helzle proposed. I've been dreaming about VEX Editor for a long time. If only one guy did it why a big company can't? He has a wonderful editor for Python too. Also, I know that at least two big company have fluid and pyro simulation based on vdb. Why don't sidefx implement it too? isn't it faster? Thanks
  10. Spring constraint on Fractured pieces

    Hey You should look into ConeTwist constraints, google or odforce forum will give you many results about it
  11. Volume Velocity to Mesh?

    HI, I think it's possible to sample velocity from volume with "Volume Sample Vector" vop or with volume wrangle smtn like this v@v = volumesamplev(1, "vel", @P); must be faster than attrib from volume
  12. Problem with smoke trail source

    Hi Vitaliy, As "Now" said You need to change your source particles, make them more like trail, don't kill them so fast. It's easy way. I mean, you need something in the middle of the trail. To push it slightly Also you could take a look at divergence field. But it'll be harder to control. Cheers
  13. rain  dripping on large  glass windows

    Hi you can use particles with sop solver i saw many examples of this effect in internet good luck!
  14. ice hummocks

    some fixes volume on some pieces was with "-" sign and volume was for one side, not for whole piece. still playing with methods for realistic ice behavior. Thanks David! I built something like that in scene, it's works well on the ground, but some pieces blowing up when it does not need to do. I'll try to add some constraint to simulation. Buoyancy_v01.hip
  15. Type of Constrains

    best course about constraints destruction and more! (must watch) http://www.cgsociety.org/training/course/destruction-in-houdini
