  1. for my better understanding: if I set an initial velocity with x=2 and a variance of 0.2 its spreading the same way as with variance -0.2. How is this handled internaly? In some cases the ability to set the variance to a negative value, hence i.e. bypassing the neccessary "self made force based vel-suction" toward the center of the travel directon, would be more than great... (iE handmade pop curve force). Any ideas or suggestions?
  2. Hi, what I am doing wrong?: i.e. a simple popnet with an pop force node. If I open my attribute spreadsheet / geometry the force will appear but the values are all 0. Did I missunderstood the general beviour of the spreadsheet or whats it? Thank you in advance, merry Xmas, stay healthy and a lot of Fun.
  3. The breaking threshold in a vellum stitch constraint (and/or in a vellumconstraint property inside the vellum solver) is in the same "range" as in prior versions, is it? I do an older tutorial (v.17.5) in v.19 and i.e. in there the breaking threshold is set to 1 while in my version I have to pump it up to 150. The dimensions of the objects are the same in the tutorial and in my file. Does anyone knows if SFX has changed the "scaling" in some Attributes accordingly to prior versions? Or something similar... And in some vellum contstraints the @stress in the geoetrySpreadsheet is much higher than the breaking threshold and they still dont break (same in the vellum constraint sop -> break and (see above) in a constraint property inside the vellum solver). Why is that? Any suggestions? v.19.0383
  4. as the title said I want to rebuild the matchsize node with vex. Could someone help me please? Also a link, tutorial or everything else would be fine. Thanks in advance, cheers and stay healthy.
  5. isnt there an easy way to hold the current scene without saving it on the normal way? I think there was one with an older qlib version.... Any suggestion for an addition somewhere?
  6. Shift+F broken

    did you also tried it in an other desktop`?
  7. a simple attribute vop noise layer: P -> noise -> add with P -> output in P and CD. the whole model becomes green and not black and white Independent wich kind of noise... - never saw that before. no materialpath attribute in it. Any Ideas? Ah: Hou 18.5.596 and GPU drivers are ok.
  8. whats that? never saw that before: on my diyplay option toolbar is a big red dot with the message: ERROR: (material/GL32/beauty_primvertnorm_lit.prog) GLSL Shader failed to compile. and nothing is displayed in the scene view. Already reinstalled HOU 18.5.496 but nothing... Any Ideas? And of course I have to finish a job today.... :-( edit: installed the newest nvidia driver (496.13) before and I think thats the problem. reinstalled an older version (471.68) of the driver and it work again... wired... Despite this would be a hint great...
  9. intersection analysis

    Phantastic, thank you. I didnt recognized the null way from the switch. Was deep in the loop involved that I missed everything outside... lol And thank you for the examples.
  10. I found this file wich is in the atachement. How does this work? I mean where are the function for deleting the spheres wich intersect each other? Is it the job from the intersection anlysis? But if so, where is the connected Output from the intersection analysis? I really dont understand the logic behind this scene. Who could give me a hint / explanation please? untitled.hip
  11. copying Matrix

    Haha, now I got it. Thank you to you both. F.. Typos...
  12. copying Matrix

    äh, I dont understand exactly what you mean...? I declared the m3 as a matrix3 the matrix 4 is needed for packed objects and/ or v and/or w, isnt it?
  13. copying Matrix

    I try to copy the intrinsic data (matrix3) from a DOP animated to an static object. Unfortunately the rotation vector is somehow funky. Have a look at the hip please: Credits: Tutorial by Alessandro Nardini on you tube: https://www.youtube.com/watch?v=s9DjkDt-6Js Smart_activation_4.hip
  14. whats the beat way to have dif. HOU versions AND dif. home directories? Is there a way to add something to the link or ow do you handle that? Thanks on advance. Stay healthy and keep going...
  15. lerp shows unexpected behaviour
