Yep it does thank you. Does that mean that in vops it is automatically clamped?

i am trying to reproduce a ramp sliding effect from vop to wrangle. I used the vop version for very long without issue,i add a parameter before the ramp to move its position(usually used to slide the ramp across UVs) For some reason it seems i am not reproducing the wrangle the right way. you can see the vop in the pic and my attempt at reproducing it in wrangle. i posted the file. script: float ptnum = (float)@ptnum; float numpt = (float)@numpt; float anim = chf("page_animation"); //slider from -1 to 1 float div = ptnum/numpt; float bend_anim = div+anim; float ramp_bend = chramp("ramp_bend",bend_anim); @bend = fit(ramp_bend,0,1,chf("bend_left"),chf("bend_right"));//slider from -90 to 90 book_odforce.hip

Hello, thank for the post . After digging on this issue i found a simpler technic that works based on "WHATISANAME" suggestion I modified your file getting rid of all the hassle of the block begin which i can't understand myself, i hope it helps. I upload the clean version i did for myself as well ready to be used test_fur_vellum_v04_SIMPLE.hip vellum_pintotarget_animated.hip

Hello, i am trying to load custom node from my galleries at startup. I know nothing about python I am able to load basic Houdini and Redshift nodes from script found , but after searching i was unable to find the proper script to load nodes from my personal galleries. i tried this to load a custom cam i made for redshift Mycam = hou.galleries.galleryEntries('cam1')[0] cam = obj.createNode("Mycam", "cam_1") EDIT: just figured out that i need to load a preset on the node.

Thanks a lot for your help. I managed to make it work, but it didn't give a good result, so i ended up using noise, like in Matt Taylor tutorial. Cheers.

yes the issue is that only the value zero is returned, so the random will not happen differently at each iteeration. I just want to use it to randomise the lerp function, so i can animate the cut in different direction(-1,1) with something like that. direction = floor(fit01(rand(@i),-1,2));
-
Yes before computing anything i need to be able to bring it in I also realised the issue was because i was deleting the original poly. So i have to rethink the whole thing, i ll try to find a way to store thee value before deleting the poly Thank you anim for answering

recursive_division.hip I am trying to randomise a for each using vex and metadata.i only get 0 as a return. I made it work in another scenarios, but i am unable to find why it doesn't work in that specific case. I used all the different script without success: int i = detail("op:../meta","iteration"); or plugged-in int i = detail(1,"iteration"); See the file attached Thanks for the help.

I manage to find a realistic way to position a train properly on a track. (see file attached) Wagon cannot simply be copied on an animated point on a curve as the centre is offset-ed in turns realistically. A path deformer is out of the question because of the deforming geometry This is my solution. 1) I created a 2 point line for each wagon 2) I path deformed the result 3) created a single point for each of those deformed line to copy each wagon onto, with proper vector for the wagon alignement I feel it is very complicated and i am curious for a better solution. If anyone interested to give his input. train_realistic_track.hip

I am doing a simple "Flag" asset with materials , texture and object embedded. All work nicely except for the "POP wind" node i place in my vellum solver which disappear when i bring the digital asset. All the rest works without a problem. What am i doing wrong?
-
from the doc: When using a Particle SOP or Spring SOP as input, it is important to keep the trail increment to integer values. Otherwise, the trail will not work well. :(
-
I am doing a small rain system. When i add the trail sop, followed by an add to connect the point with the ID attribute, everything works fine until i set the trail increment to a value different than 1, then it completely breaks. I believe it is because particle are dying, but i cannot figure out how to debug it Trail_sop_issue.hip

I can't make anything follow path correctly, it simply doesnt work or when it works(with a camera) i cannot keyframe the position parameter On null nodes there is no position parameter either What am i missing? EDIT: Thanks to MiesnerMedia 1) Go inside the object you want to constraint to a path 2) create a "constraint (chop network)", go inside and add a path node. 3) select your path object in the SOP path parameter

Hello, For some reason i can't set a keyframe on the position and roll parameter to animate an camera along a path. I works for other param, like transform etc. It has been a persistent issue for a couple of version for me. The issue happens on any object container. Any help would be really appreciated as i am on a tight deadline FOUND A SOLUTION: I added a carve node on the path and animated that instead of the position parameter on the geo. well it works.....

Should we rejoice or be scared for new tech like that. What happens when anyone can do pyro-effect, with a couple of clicks? That said it looks quiet impressive for real time.
