  1. A question about geometrical procedural deformation.

    ``` float start = chf('start'); float touch = chf('touch'); float speed = chf('speed'); float flip = 1 - chf('flip'); vector fade = relbbox(0,@P); float amp = chf("amp") * @Cd.x; float fade_x = chramp("fade_x_ramp",fade.x); float fade_z = chramp("fade_z_ramp",fade.z); float fade_y = chramp("fade_y_ramp",fade.y); matrix m = ident(); float copy=( ch("../copy1/nyc") - prim(0, 'copynum', @primnum)) * flip; float t = @time * speed - start - copy + sin( fade_x *amp) + fade_z * (touch*fade_x); rotate(m, smooth(0, $PI, t) * -$PI, {0,0,1}); @P *= m; The work proceeded in the direction I wanted using the ramp parameters referring to the code in the hip file. I was able to complete the code with the advice of a senior at the company, and I will leave some of that code behind. And at the end I used a position mix. Thanks to everyone who responded.
  2. A question about geometrical procedural deformation.

    Hello. I used x, y, and z respectively as ramp parameters. And it had to be animated. The way you said was a good reference. Thank you very much.
  3. Rigging a book

    Thank you for answer. How do I make it go left to right instead of right to left? thank you.
  4. Hello. I'm trying to make a bunch of money. I tried using vellum, but it didn't work, so I referred to the page turning hip file at the address above. I want to apply both left and right, but I don't know how. If you have any good ideas or examples, please let me know. Thank you.
  5. Rigging a book

    Hello. Thank you so much for sharing. I have one question. How can I adjust both left and right? I don't want to use animation, I just want to create a feeling of fluttering left and right (?). Please advise. thank you.
  6. How to Copy Houdini's Mantra to Nuke

    just need to load rendered image. Should this python code apply to both Houdini and Nuke? I want to have the image load when I copy the mantra to Houdini and paste it into Nuke. Thank you.
  7. Hi. I have an image rendered with Mantra in Houdini. Please let me know if there is a way to do it with a python script. Do you know how to copy only this mantra node to Nuke and that image can be loaded directly from Nuke? Thank you.
  8. Help with volume retime issues.

    I solved the retime problem by simulating a 24FPS operation to 96FPS and then turning it back to 24FPS. But I don't think this is a perfect solution... 1. When there is only density, if I use the retime node, the feeling that the quality has decreased every frame repeats. 2. When there is a field other than density. In the case of an explosion, the fire will flicker. Is there anybody to help? Thank you.
  9. Hi. I'm going to try vellum grain! After creating vellumsource in dop 1. Put only geo(../GEO) source in the sop path of the source and 2. Put geo source in sop path and constraint(../CON) source in constraint sop path in two places. Will the vellumsolver work differently? When I test, the result value seems to be the same, but method 1 is wrong, and I heard that the constraint source must be added to the constraint sop path like method 2. If there is any difference, please let me know what it is. Thank you.

    Thank you!
  11. meshing fractals

    Hi! Your work is so cool! I'm looking for fractal noise and it's difficult. Could you please share the hip file with me? Thank you.
  12. Hello. I'm making an explosion. It is an explosion that enters a plate shot at high speed. I am wondering how to approach it.. Is it necessary to retime after adjusting the time scale slowly from the beginning of simulation work? And there is a problem that can't be solved, such as flickering or interruption in the volume when retime is performed. Does anyone have any advice on this? Thank you.
  13. Hello. I'm going to use the sparse pyro that comes with version 18. However, I want to apply the pump vel to the sparse pyro, but it does not apply. (I brought a pump vel to the source volume and used it, but it cannot be applied.) If anyone knows what to do, let me know. Thank you.
  14. Oh my god... I was impressed with your kindness. It has helped me a lot. Thank you very much!!
  15. Thanks for sharing. Is it part2 too?
