  1. Mantra vs Redshift

    ;-) not that impressive!!! héhé thanks for posting it, Very amazing and interresting! Jean-Marc
  2. Hi, I have a problem with nested FOREACH SOP, something is strangely wrong but i am becomming crazy right now to find why ;-) the resulting object from this loops is strangely translated, i have made this snapshot with in-between transform values to show immediately the problem: (dont see where i can put pics inside the forum) https://goo.gl/photos/sZDiFBKFrPHJL4QL8 any idea? Thanks! fake_extrude_on_each_line02.hipnc
  3. Thank you so much Tomas! Great solution and much more smart and simple. i learn a lot looking at your file. Cheers, Jean-Marc
  4. Extrude along Curve

    Hi David, Did you check this tut? hope it helps https://www.sidefx.com/tutorials/polyextrude-curve-input/
  5. Hello Dears, I think i am not far from something, but i still have a problem with the nested foreach that bring the facet to the copy sop, It is ok when i use only one iteration in this loop, kind of degug way to see it could work ;-) may be its clearer with pics... leaving maxiteration as default should work but it copies only the first face on all the template points... as you can see here with maxiteration at a certain value will copy this face id on all the points, so one is correct... maybe i should write some expression in this maxiteration attribut? i have attached the file if someone wants to see. Thank you fake_extrude_on_each_line03.hipnc
  6. Shading a Jellyfish inside Houdini

    Hi Guys, Incredible and challenging pictures at the beginning of this post!!! i did one animated fantasy jellyfish while learning houdini. you can see here: I am a little bit off topic because I id everything in Houdini except shading lighting wich was in Maya using 3deLight wich i am more familiar with... cheers JM
  7. H15 polyExtrude with curve

    Hi All, I am trying to have different size in a polyExtrude with curve. ( i would like also to deform differently them...) i am using a forEach SOP trying to do that it seem that distance is not working with the detail attribut "iteration". i am quite sure it is possible but i am lost with all of that... any idea would be great and welcome! thanks forEachCopyExtrude.hip
  8. H15 polyExtrude with curve

    The way you did this is very interesting and smart! i still dont understand why the last points are sticky like this in the left example, though the animation looks correct ... thank you for the little different tricks you put inside: split sop, clean set of source points etc, i learned a lot
  9. H15 polyExtrude with curve

    Thank you, it's really cool. So i tried to use your ideas with a pre-animated set of curves, mainly yours Mestela, though the other way you gave F1480187 looks cool too, but i didn't know how to choose the curve with the switch node, anyway, i get nothing . It's not updating the curves frame by frame as expected... It's also a bit too complex for me.^^ I was wishing to give a working scene but i had to give up ... to much time spent for nothing here is the scene i got but keep in mind it's not working ;-) rand_polyextrude_on_animated_curves.hipnc
  10. H15 polyExtrude with curve

    Thank you Konstantin, The videos are very interesting, almost the one from Rohan Dalvi. i am trying to figure out how to extrude each face with a different copy/animatin/size, etc of a curve. I think that the idea is to import a curve and a face in the forEach SOP and to give them say the same attribut for deformation changing along the iteration It should work :-) Thanks
  11. Hi, What would you guys do to access an attribut value inside a Ripple SOP? say I would like to scale the force of the ripple depending on the value of this attribut on a point basis? (for example the Cd attr) when i write down this, i get errors: 0.5*point("../point1", $PT, "Cd", 0) thank you!
  12. accessing a variable in Ripple SOP

    WOW Thank You Georgie! working as hell!
  13. Aloe Vera

    Absolutely great work ! love the shading and rendering part it is quite perfect compared to a real Aloe Vera except the extremity who is vanishing in one needle but this is a detail :-)
  14. Hi there, I cant figure out how to "bake" transforms of some RBD objects, if possible separately. > Say i have 4 cubes colliding on a ground and between each other: i would like to be able to bake their passive animations in order to replace them by a more complex object... Edit: just a way to replace them by another object at rendertime or to constraint another object on each cube separately would be great jm
  15. baking transforms of RBD object

    OK, i was in the wrong section ... answer here for any noob like me:
  16. transfer UV

    Hi, What is the workflow to transfer UV between 2 objects (from 1st objetc at frame 1 to 2nd object globally) Thanks for any help jm
  17. transfer UV

    Great! I really appreciate your help ! Houdini rocks!
  18. transfer UV

    thanks this is the file, see at the bottom of HEAD node where i think is best to unfold the uv jelly_07_d_withoutTentacles.hipnc
  19. transfer UV

    thanks for your very fast replies!!!! here are 2 pictures illustrating the problem: the first one is at frame 1 while the 2nd at frame 20, the uv's are swimming animation is based on the same curves that are used to model the object, thus the object is already moving before i can apply uv's on it ... also i need to have dynamic uv because this asset can have different structure i have thought about attrCopy, but i cant see any uv in this node . jm
  20. && in expression in group SOP

    Hi Magicians, in a group SOP what would be the correct expression if i want to select only last and first points of a group ? it look like never mind what is after && , it is nor evaluated ($PT > ($NPT -2) && ($PT < ($NPT -($NPT+1)))) jean-marc
  21. && in expression in group SOP

    Thank you Sadhu!
  22. Hi, i m learning Houdini, so excuse me for this noob question :-) I am trying to get a value i have animated but at $F+3, i have tried to grab this value from inside a timeShift OP and/ but with no success. for example say, i would like to be able to make some calculation between those 2 values to animate another node i have seen something like this before but cant put my hands back on it jm timeShiftAttr.hipnc
  23. how to get the value of an attr at FRAME+3

    THANK YOU 3dbeing! it's exactly what i was searching for (i have updated the little example if someone(noob like me)is interrested.) jm
  24. extrude edges on a curve path

    Hello all, Is there a way to simply extrude edges along a curve like it can be done in Maya? Thank you Jean-marc
  25. extrude edges on a curve path

    WoW very interresting to study, thanks a lot! need some time to understand everything, but it might be exactly the good way for my little problem Cheers Jeanmarc
