  1. Hello masters! I am just asking for advice. I want to create a simulation of worm movement with vellum softbody. What I have so far is an undone node tree, and I don't know how to apply this wavy behavior to the geometry. So may I just kindly ask u to help me out? It's a very simple scene, but I don't know how to execute the sopsolver inside the dopnet . (I am not even 100% sure that all the steps I did are right) I will be very thankfull, for any advice.... worm_motion.hip
  2. Vellum match animation

    Thank u soo much man, that's exactly what I was looking for. I tried it out, BUT I need to scale it down to a smaller model (1m). So I recreated it a little bit, and it's not working correctly. The waving behavior effect is not appearing on the model, even if I increase the scale in POPwrangle in dopnet. May I ask for advice? vellum scale issue.hip
  3. 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

  5. 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?
  6. 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
  7. 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.
  8. 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
  9. random rotarion added to the each Y axis

    Exactly what I was looking for! Thousand thx
  10. 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
  11. 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
  12. 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
  13. object scale change, durring rbd sim

    thank u. works perfectly
  14. 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
  15. 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.
