  1. Break up wave pattern in the Ocean

    Hello all, I am working on a Ocean scene right now, I have created a unfinite Ocean but now I have a problem. So, there is these strange pattern in the ocean (like in the picture). And now my question: How can I get rid of these patterns? what i have tried so far: 1.) I have try to mix two Ocean spectrums, it hasn't worked... 2.) I have try to turn on the make in the mask tab in the ocean spectrum, i hasnt worked too... is there a straight forward option to how to this??
  2. Flip fluid problem

    Hello, I am working on a ocean scene, and everytime I want to flipbook my animation then I get an error code after some time: "OpenCL Exception: clCreateBuffer (-61)" and this many times... like this: OpenCL Exception: clCreateBuffer (-61) OpenCL Exception: clCreateBuffer (-61) OpenCL Exception: clCreateBuffer (-61) OpenCL Exception: clCreateBuffer (-61) OpenCL Exception: clCreateBuffer (-61) OpenCL Exception: clCreateBuffer (-61) .......... and after some time Houdini is crashing... how can I fix this problem? my Hardware: CPU: 1920x Threadripper (12 cores) GPU: AMD HD Readon 6990 64 GB Ram Would be very glad about help!
  3. Water shader isn't working properly

    Hello all, I am working on a scene with a ocean in it. When I am trying to change the water color then I am going to the materials tab and after that I click on the "uniform_volume" material And there is an option called "smoke color", so I am trying to change the color of the "watersmoke" but nothing happens the color stays the same and its re-rendering the scene... It has worked in the beginning as I has started the project but now it isn't working anymore... would be very happy if someone could take a look at my file and then write what was wrong. Best regards Daniel Starship_liftoff_full.hipnc
  4. right vex code for velocity to particles

    Hello, I am thinking that I've forgot the vex code for giving birthed particles some velocity... I have used this code to give some velocities to the particles... @N = @N @v = @N but now I am back at Houdini and I have tried it again and somehow it isn't working anymore... And how should I start to achieve the result like in the video? I am trying to get the main explosion burst on the torus so that I can use the same way to my already modeled falcon 9. There is a "ring" of smoke which I like to replicate to my torus... The air explosion from 0:18 to 0:22 I would be very glad if someone could help me Thanks in advance (
  5. Pyro trails explosion

    Hello, I am trying to recreate the trail explosion at the beginning WITHOUT the rebelway course. I want to challenge myself so please don't say that I should buy the course. I have set the challenge by myself I have figured out how to achive the particle trail simulation and I can do this without any problems. But now I am stuck on the smoke/fire part. I don't know how to attach the smoke correctly to the particles when the particles are moving with fast velocities. Because when I am pressing the pyro fireball shelftool then my particles are showing like smoked points even if I increase the pyro substeps. I can do the particle simulation without problems I hope probably someone could help me here
  6. Hey all I am wondering if its somehow possible to time (timing) multiple or many pyro explosions to the beat of a soundtrack? If yes how can I achieve that? please let me know. Thanks in advance
  7. Setting up pyro sim right

    Hello all, I am a beginner at Houdini, but I try to understand some VEX coding, some easy coding to give velocity to normals. Now I am trying to achieve a Explosion with trails. I have set up a particle system where I have given some velocity to the particles. Now I am trying to use this particle system to drive the smoke/explosion simulation. But I don't know how to set it up right. Because I have tried the shelf tool "Explosion" and "fireball" but the result looks not so good. The smoke on the particles are dots. I have tried to increase the substeps in the pyro solver but nothing has changed at all. is there a right way, probably I do it wrong in some way. I am provide my Hip file here, in the case if someone knows how to do it It would be very thankfull. trail explosion_training.hipnc

  9. Make smoke stick to particles

    Hello all I am trying to achive a twister sim with some particles. I have already set up the particle simulation and now I am trying to do the smoke simulation. But somehow the smoke is not following the particles or the smoke is going upwards. How to fix this problem that the smoke should go downwards and not upwards (see screenshots). And there is the hip file as well. Tornado_test1.hipnc
  10. Make smoke stick to particles

    Thank you, for your work and time, but i am a newbie in Houdini, And as I saw the node setup my heart has stopped beating haha xDD (thats much nodes!) But thanks again
  11. Strange water simulation

    Hey all, Something is strange with my water simulation. When I press on "Flip fluids from Object" and then pressing "Play", the "water ring" is falling instantly down. But there should be a constant falling water sim. Thats my first time I have this strange problem. How to fix this? Thanks in advance problem with fluids.hipnc
  12. Strange Exported Video

    Hey all I have a strange problem with my exported video from Houdini. When I Render the Simulation out, then in any other video applications the flame is cutted out. I have render maaany other pyro stuff and thats my first time this problem have showed up. How can I fix it? The files are attached. You must download all "obj" files because I have assembled the rocket from each part.

  13. Strange pyro cutoff

    Hey all I have a strange problem with my pyro sim. The flames are cutting of in the Render view tab. (like in the picture)... What is caussing this? I have press more times before that the "smokeless flame" shelftool and everything was fine...but since one moment something is strange there... :/ Help would be very nice..
  14. Strange pyro cutoff

    you should try some other perspective try from a bit far away and look from down...

  17. Mplay moving issue

    Hey all I have a strange problem. After I have minimized the mplay render window and reopen it after that my middle mouse button isn't working anymore. I can't move the renderview window and cant even open the topics like "File" "view" "Render".... in the Mplay window... How to fix this?
  18. Thank you so much!!! I really appreciate it
  19. Hello all, I am struggling since some months on a problem which I cant solve, I have tried so many things like, have searched YouTube Tutorials but they are for older versions... My goal is, i am trying to do a easy fracture sim like a ball hitting a wall and the wall crumbles. But then I click on the "debris" shelftool and after that I am stuck on the problem, attaching some of the fractured pieces on the particles... I want to learn this on some easy fracture set-ups so that I could apply it later to some complicated set-ups if necessary. I would appreciate some help. and if someone of you had time I would be veeery glad about a Hip file for this problem
  20. Hello all, I am struggling since some months on a problem which I cant solve, I have tried so many things like, have searched YouTube Tutorials but they are for older versions... My goal is, i am trying to do a easy fracture sim like a ball hitting a wall and the wall crumbles or something falls down and breaks apart. But then I click on the "debris" shelftool and after that I am stuck on the problem, attaching some of the fractured pieces on the particles...

  21. So I have here the file I want to randomize the fractured pieces and attach they to the particles... Fracture copy fractured pieces to points.hipnc
  22. Strange Collision Guide behavior

    Hey I have a very strange collision guide behavior. I have an Object, which is like a drum with 3 entries which should collect some small grains. But my collision guide shows me that all 3 entries are not big enough (but they are big enough). I have some measurement requirements so I can't do my drum bigger as it is now. see screenshot. And when I increase the division size then there isnt any collision with my geometry. If someone has an idea how to fix this problem and why Houdini is telling me that if the entries are not big enough for small grains. Thanks
  23. Houdini pyro particles explosion

    hey all, I have two questions: 1.) How to add smoke and fire to the particles, inside in the geo node? 2.) How to put the particles together, like trails...? I am very confused.. explosion_2.hipnc
  24. Create a Trail explosion in Houdini 17.5

    Hey all, I am trying to do a explosion like this in the picture. I am very desperate, I have searched up the whole internet around but have find nothing... I have tried to do some particle emitting from a sphere with some forces but it wasn't like this... Can someone help me please... ps. if someone have time to make a hip file for me it would be a bigger help thanks in advance,
