  1. Particle workflow popnet

    Hi, So I was fiddeling with the popnet and finally got a nice stream of particles, but it doesnt render. It's in the viewport. But it does not render. What I have are several lines that are used for creating geometry. all these lines are in one geoSOP. I want to use the a single line as a source for popnets for my particles. Also for all other lines. So I created a subnet for this so it can be copied and paste. So everything in in one geosop. Now for some reason the particles only show up in my viewport, but the particles does not show up as spherers in the render. Therefore I made a little test and created an empty geosop on obj level with a popnet. This time the render does show the particles as spheres. So, what exactly is the right workflow for particle effects, so that I can render them. And what is wrong with my first approach. Hope you can help out. Thanks in advance, M
  2. Hi I am absolutely new to houdini, so sorry for my ignorance. I'd like to give a mist-like shader to my particle animation which made me struggle whole day..... I dropped billowy smoke shader to spheres, and suddenly my particle object wasn't seen in the render view. How can I make it looks more realistic? I have attached my scene file. Help me.........(༎ຶ⌑༎ຶ) +) I think my particle effect is far from the perfect aerosol spray effect, so please feel free to give me some advice to make it better. I'm trying to make it as a volume with a VDB node, but not sure that it is the significant try. Thanks for reading. aerosol spray.hipnc
  3. Particles do not move well

    Hello. I'm making a blaster referring to the tutorial. But, it stopped at the first stage of moving particles. For some reason, the particles get stuck without moving. I tried to increase the velocity, but did not move. Could you tell me who will attach the file? Could you help me... blaster.hiplc cave_cache.bgeo.sc E 45 Aircraft_obj.obj
  4. map uniform pattern on a geometry

    Hi, I have been looking for a way to create a model that has a certain pattern (like tri, quad or hex - whatever being convex or hole). It is something like this in the picture but the pattern should be all universal in size and shape. (in the picture, the upper part goes smaller and the bottom part being squashed) I understand by doing this, it most likely changes the original shape of a model though. Cheers,

  6. Hello, I have a particle simulation in Houdini that I exported in a .bgeo sequence and collapsed into a Digital Asset. I import it in Maya using the Houdini Engine plugin, which allows me to load the .bgeo sequence. After shading, my particles are visible both in the viewport and in the Arnold Render View. Everything looks good. But when I try to render them using Render Sequence, they disappear. Same thing for Batch Render. I've tried looking through all the AOVs, using render layers, but my particles just won't render. Is there anything I'm doing wrong? Is the problem coming from the way I export my particles in Houdini, or from Arnold itself? Thanks in advance.
  7. Hi ! i'm trying to render particles in redshift. I need to use noise in shader, but the problem is that particles are moving on SOP level and noise also sliding along surface as well In the case of mesh object i just use rest attribute and all is ok. Noise is foxed....but in the case of particles RedShift does not take into account rest attribute on particle.... so it causes noise to move (((( and it seems that we do not have an option to set custom data for noise seed ... it uses only obj position or some vertex data, that particle does not have.... is there any way to get what i need ? to apply bump noise on moving particle and fix it on this particle .... here on picture i have only one particle and it's moving....and bump ((((
  8. I currently have a Pyroclastic flow sim that I made by using a particle sim, caching it with a DOP I/O node and then into a smoke sim. I works great and as I want it to. However as soon as I try and delay the sim to any frame it breaks either the particle sim or the smoke sim or both. I watched hours of vids and tutorials trying to figure what I've missed but every way I've found, including several suggestions I found on here, have failed. I've added a bunch of photos below of the how I've set it up and if anyone could tell me how they would go about delaying the simulations to a certian frame or something I've done wrong I would be enternally greatful. If I need to add any more detials please let me know.
  9. hello i am trying to create weld effect using pop replicate and pop collision detect. i want to emit(replicate) another new particle from replicated particles. my planned work flow is Pop location → Pop replicate1 when collided → Pop collision detect for ''just born group'' of pop replicate1 and replicate new particle from those replicated particle however pop collision detect works only for first replicated particle1. it doesn't detect the replicated(just born) particles are there other work flows to create ''double'' pop replicate weld effect ? particleprj.hipnc
  10. Birthing particles dynamically

    Hi All, I'm trying to get this setup working where I have particles that are being activated and turned on before being fed into a pop net. I'm stuck as to how i might be able to birth only each initial particle as they're activated into the popnet. I'm trying a couple of expressions in the impulse activations, but not having luck. I'm currently birthing particles at a constant rate every 5 frames, but what I would like to do is only birth once on each incoming particle. Any help would be appreciated as I'm still learning this Particle_Growth_example.hiplc
  11. So I've been looking for some time on the internet how to do this seemingly straight-forward thing. I have a pretty simple particle sim with a copy to points to attach a plane to each particle. Particles move a little with a popforce inside a pop network and thats it. I want to export this simulation into UE4 with the plane attached to the particles. I tried: - The gamedev "rbd to fbx" node and try to make it work with particles, I couldnt make it work. - Export it as FBX, in Maya it works but in UE4 it exports it as a Static Mesh. I wanna know if theres a way to export the particle sim into UE4 so I can use the planes to attach any texture I want. Theres an image for more context. Also if theres a way to bake the simulation as an animation with keyframes or something like that (not cache to disk). Thanks in advance!

  17. Hello to all people :)! I’m trying to do a few days, a whitewater that surrounds my boats, creating the tip of a wave at the front of the boat, a little like this example ... https://forums.odforce.net/topic/28940-flat-tank/?tab=comments#comment-164200 or that one (Really a defined shape of the whitewater fallowing the boat from the front to the back.The problem, here ... I can not see why the whitewater does not seem to be done and do not keep the shape of the same smaller boats ...) I would also like to know ... how to bake my simulations in order to have an ocean that included my simulations of my boats, with also my whitewater :)? Thank you in advance for your help :)!!

  18. hi, I am testing vellum, and have a question. When testGeo is coming up from ground, all vellum particles are influenced and pushed away. Also, when he hit ground with hummer and lift it up, particles looks being sucked into holes made by hummer. However, these particle reaction should not reach such far away distance. I'd like to know how to control the influence distance. So far, I am thinking of solutions: 1 - reduce constraint iteration, 2 - make a space between particles at emission/creation times. 3 - add more friction, increase particle separate / highres- sim, etc. This result could be ok for sand FX, but when making snow ground, this won't work. Particles should be very rigid, and particle only moves around testGeo's feet and hummer. If anyone knows how to control it properly, let me know thanks!!
  19. Updated Tornado Setup

    Hi all, I found this awesome setup for creating a vortex around a line by using point cloud data but its being created using a POPVOP in a dopnet. Would anyone know of a more updated method? I'm mainly wanting the great velocities from the base that spiral up the line. Any info or setups would be great to see based on the file. Thanks! tornado_v01.hip
  20. Hello, I have a popnet with that emits one particle every 10 frames and I need to increase substeps to get more accurate result...however when I increase substeps it affects pop source and emits more particles. For example if I have 3 substeps, it will emit 3 particles instead of one. I've tried using gasintermittentsolve but when using that it just won't emit anything at all unless frames between solves is set to 1. Is there any other workaround for this? Thanks

  22. Asking for some solution on FX

    Hi I'm working on my short animation project. I'm tasked with doing Magic particle, RBD, Cloth sim. Right now I have some problem that I'm little bit stuck. Getting help would be nice since I have no one to ask right now 1. I'm doing an earth spike. The type of Rock coming up from ground. I have a problem of making the ground "Not fall with gravity". I want it to be like a ground plane that If the rock hit it. It just fall. Not before that Right now, I'm using the attr transfer with the center of the ground that break will be active=1 and outside will be = 0. The thing is the area of the active=1 is fall due to gravity pull it down before the rock hit it. Any advice? like this https://vimeo.com/manage/280683899/general It's fall before the impact coming in. 2.Any tips and trick on making nice particle look/shading in redshift? I'm mainly using advect by volume for shape. And in shader I just use Rsmaterial with rsparticledata>illuminating colour so it does glow. any advice on making it look good? 3.I'm lost in cloth sim. Any tutorial on vellum cloth that explain about how to constraint point to charactor? I'm mainly doing the hood sim. Thank you! If i'm not clearly explain it please tell me.
  23. why render the particles is not alpha when used the glow shader if enable the emission? How will I to do? Please
  24. Recursive Particle Split

    Hey guys, how can I duplicate particles recursively? Sort of in a fractal / l-system way, to simulate veins, bramches and stuff like this Thx
  25. Random geometry instance to particle

    Hi guys, I made curve flow particles and want to instance it to some petals. I made 5 patterns of petals but have no idea how could I randomly instance those patterns I'll render these particles using Redshift. If you have any idea for instancing 5 geometries randomly, Please help me ! Thank you for read !
