  1. Vellum match animation

    Hello Houdini wizards! Very simple question. Can u help me with the very simple logic of the locomotion exercise in my file? I am basically trying to achieve the effect of waving the object during the calculating process of vellum struts / vellum tetrahedral animation. I am attaching the link with a video, where u can observe the effect I am trying to achieve. I also created a very simple scene, but its not working. So can I kindly ask u to help me explain in my file how does this merging of animation+vellum works? It would be a big help to me. Thank uuuuuuu ripple_issue.hip

  3. rest length to color range

    Hi guys! Can I ask u to help me out with the following issue? I created 6 simple spheres, which are being inflated in 30 frames, and what I need now is to get colour information about the stretch of each vertex, and transform it into the colour (I am not sure I am describing it right). But what I basically need is that parts of the ballon that are not stretched and stay in the same position should be darker and parts that are stretched should be brighter. I need this Cd information for updating a translucent map during the animation, so where the balloon is stretched shader should make the surface more translucent and also opposite way. Thank you guys so much for any advice! Baloon_issue.hip
  4. rest length to color range

    Hi houdini Master Thanks for your swift reply!!! I had the same plan in my mind. However, can I ask you for an example in my attached scene, so I can o through it?
  5. gradient ripples defined by paint

    Thank you so much Aizatulin! I am super bad at VEX commands, so I do not know how to create even this super-simple logic wrangle.
  6. Hi guys, I m sure this is gonna be a very simple exercise for ya. What I want to get is to create a gradient/smooth movement of the ripples for selected points, defined by painted colour. Where its darker the ripples should be more prominent and points should be moving strongly, and also opposite way, where its lighter it should be less visible and points should be almost static. Now the ripples work same for all of the selected points, and it creates very sharp edge on surface of the model. I hope its undersandable from this super-short brief. I have some ideas about how to multiply the position of the ripples added to @P by @Cd but i do not know how to combine these two values in pointwrangle. I am sure u guys can help me out! Thank u guys for any advices. issue_ripples.hip
  7. random rotarion added to the each Y axis

    Exactly what I was looking for! Thousand thx
  8. Hi people! Justa superquick issue I need to keep the normal direction of the point, so all the heads will be oriented along the normal direction. BUT I would like to randomize their rotation around the Y axis, so they should not be all "looking straight up" but they should be ALL randomly rotated along each of their Y axis. I hope this explanation does make a bit sense. I am attaching the file. Thank you so much for any advice guys! rotY_issue.hipnc
  9. vellum cloth self-intersection

    Hi guys! Justa quick question. Im trying to achieve this kind of effect: Very thin plastic plane (has to be thin besause of tiny wrinkles) on animated skeleton. BUT unfortunately it doesnt work quite well, bcs there are so many self-intersections, and also intersections between the dancing skeleton and plastic plane itself eventhough I set the substep to 10.... :/ can anyone help me to solve this issue, please? THX so much Here u go the hip. dance.hip
  10. scale vellum / struts like rigid body

    Hello houdini folk! Quick question, is possible somehow scale the vellum struts, during simulation? what I want to achieve is simulated in dopnet in attached file. Essentially I just want enlarging pighead but in vellum, with struts. Thanks for any advices! vellum_scale_like_rigidbody.hip
  11. object scale change, durring rbd sim

    thank u. works perfectly
  12. object scale change, durring rbd sim

    Hello, Houdini folks! I have a question about very essential thing durring the rbd simulation. (Im attaching the file here). What I have, I want to change the scale of the pighead, durring the simulation, but without this "strange jumping" behaviour. Any suggestions, how to solve? Thank you so much. strange_behavior.hip
  13. Hello Houdini folks! For first let me wish You happy new year! And for second, let me have a tiny question . How can I render in Redshift transparent background png. with hdri lighting (RSLightDome)? Is it possible somehow? Thank You very much for any advices. And finally, can I kindly ask U, to post a hip. file, or print-scr with this "transparent-background" preset in your attachment? Many thanks Michal.
  14. trail velocity issue

    This is exactly what I want. Thank U so much Jirko!
  15. trail velocity issue

    Hello Houdini folks! I have tiny issue with trailed particles. Is possible to visualize somehow it's velocity like in the picture in attach? Thank You so much for any advices and wish You Happy New Year!!!! vel_issue.hipnc
  16. Vellum-popnet issue

    Hello Sean" Thank You for your response, it works! And let me with U mery Xmass and Happy new Year! But there is still problem with deforming of these testing geo's durring animation. And I dont know how to fix it. I already tried to slow down particles, and increased substep (in velum solver) but it still looks like randomly displaced mesh. Can u help me one more time? Thank You very much, for any responses or advices!
  17. Vellum-popnet issue

    Hi houdini nation! Can I have any advice? Im trying to make animation of 5 testing geometries which are coliding between them selves. The position and rotation is defined by popnet, but when I connect it with vellumcloth, it doesnt use any animation data, even if I set Match animation in vellumCloth node. Can u help me pleas fix this issue? Thank u so much for any advices. issue.hip
  18. particles around the mesh

    Hello Houdini guys! Can I Ask you for any advices in case of my issue? I would like to know how can I get same (or similar) result as down here in the scheme. (I am also attaching my simplyfied hip. file) I would like to force particles to the surface, but not let them just slide on that surface. Hope you understand what I mean. I will be very grateful for any advices. Thnak You guys. A: is how the script works now B: is how it should works issue.hipnc
  19. popdrag - slower particle in selected radius

    Hey James! Sorry for my very late reply. I was quite bussy for long time. I fixed this problem by myself but it was done by very hard and crazy kind of way... I like your approach... thank u very much for your help!!!!!
  20. Hello houdini masters! I have small issue, in popnet. Im trying to create moving particles on plane, but with different "speed" U can see my intention on scheme down here. Can u guys please help me? I will be very grateful for any advices. Thank u very much!! particles_issue.hip
  21. popdrag - slower particle in selected radius

    Thank u so much James, now it works! I added more "falloffs" and it works perfectly!!! Can I ask U one more time? I have problem to put particles just inside of the object (i mean not sliding on the surface, but flowing just inside of the geometry). I tried poplimit node, but this works just like BoundingBox, and I need to defined it by my specific geometry... maybe u can help me fix this too... And Thank u again for your previous explanation and help. cheers pop_inside_issue.hip
  22. popdrag - slower particle in selected radius

    Hey Drughi OMG! How u guys are doing that?! works.... thank u so much!!!! But how to make it with multiple "center points". I mean more centers with slower motion of particles. I tried something in popnet/ pop vop, but unsuccesfully.... particles_issue.hip
  23. Hello guys! Can I ask U question, Im very new in houdini. Can u help me please? Im trying to render short video of volume (smoke) in matra, but I really do not know how to set the mantra settings, because one frame is mantra creating for 43 minutes, which is rediculously long time for 250 frames. can U help me, with settings? I already increased the Volume step size, but thats all what I did, (I read somewhere its helpfull) is there any other way, how to make render time (per frame) shorter? Thanks a lot for any advices! Im looking forward to your re´s! By! advice.hip
  24. Ramp between three textures - REDSHIFT

    Thank you so much!
  25. Good evening! Can I ask U guys for advice? Im trying to create ramp between three textures (but with same uv map), defined by paint SOP on pighead testing geo. And what I want to ask U is: Does it possible to somehow assign different textures for each color, in redshift? Any advice will be very, very helpful to me! Thank u guys so much! textures_issue.hip0.hip
