  1. I am quite new to vellum, but I searched this for a while and couldn't find a good answer to it, so hopefully someone here can help I have several small pieces of cloth that collide with the ground and animated characters, somehow single points of my cloth seem to get attached to the colliders and fixate to it, stretching out. Any ideas?
  2. I am working on a shot where a very viscous fluid hits a character. Everything is working great on the sim and giving me look I need, but I was wondering if I could add a "stretch limit" to it somehow. Like "if it stretches by x amount, break it up into smaller pieces" without losing the viscosity much or getting it back after the breakup. I am not sure what attribute I could reference for that (if there is one). Help me odforce, you're my only hope.
  3. I have a feeling this might be a dumb question, but I have been stuck on it for a few days now. Or maybe not so, as I've been looking countless treads here, but none really solved my problem. I've got a really simple setup, pop curve force guiding some rbd objects (I also tried doing it with points and copy stamping after sim to the same result). At a point in the sim the vectors start to point outwards: What I would need is for their direction to be always facing forward as they are at the start: I've had some luck with using pop torque, but still not what I need. I've attached an example file and the curve alembic. RBD_Directional_Vectors_Curve_Force.hip curve01.abc
  4. Cloud timelapse approach?

    Thank you very much for all the answers guys! Atom's Method worked really well
  5. Cloud timelapse approach?

    My current method is using a geo, cloud sop and cloud noise to get the clouds working. I tried changing the shape of the src, but it didn't quite give me what I wanted.
  6. Hey Guys! I was wondering how I would be able to achieve this: https://www.videvo.net/video/blue-sky-and-clouds-timelapse/2299/ I've found a few ideas around, but I was wandering what you guys would think is the best approach? I have tried with a sim but it feels like what I'm missing is a good way to have the "shape shifting" of the clouds work. Thanks
  7. Pop Grain issue! Please help!

    Thanks man! This worked pretty well!
  8. Pop Grain issue! Please help!

    Thanks guys I'll give it a try tonight
  9. Pop Grain issue! Please help!

    I used a pop speed limit with a lower and higher speed, would that be the same as using a pop wrangle for it right? I never used chops, do you know any place where I can learn to do that?
  10. I've been stuck on this for a couple of days now and would love to hear you guys' input. I have close up shot were a character's feet is pushing through snow up to his ankles. I decided to try grains for this (it's my first time really using it) and to get the snow together I used the constraints set outside in the grain source. Mostly the sim is working as intended but I'm getting a lot of unwanted fast movement from some particles (as if they're trying to keep the constraint but not really keeping it, so they pop in and out, and that results on a flickering on the meshing. Did anyone come around this problem before? I am up for any solution at this point, even trying another method.
  11. damn I might be a few years too late hahaha
  12. You're on the right track. You can just use convert vdb right after the pyro to convert it from a houdini volume to a vdb, then use another convert vdb to get the polygons. There is a tutorial that goes a bit more in depth about this, specially the shading: is this what you were looking for?

    Thanks Bathyscaph

    Hey guys saw a good deal on this pc by HP and was wondering if I should get it, here are the specs: Processor Type 8th Generation Intel Core i7-8700 Processor Cores 6 Processor Cache 12 MB System Bus 8 GT/s DMI3 RAM 12 GB Graphics Card NVIDIA GeForce GTX 1070 Would definitely need an upgrade on the RAM, but other than that do you guys think it's a good buy? The graphics card is not listed on SideFX and that's my main concern.
  15. Extended Ocean Alternative

    Just if anyone comes looking for this, I'll post the "solution". At the time I posted this, I've been using only Houdini 16.0.504 and this version has the extended extremely bugged. I upgraded to .671 and that gave me better results, even tough the camera frustum still gave me crazy results, like for instance, when it touched the the bounds of the camera the plane started to go up. But other than that everything worked.
