This one has me stumped - is it possible to move and offset (not retime!) Spectrums and corresponding Foam caches post sim? I'm rendering an Ocean in Karma but need to transform and offset it at render time. For previews I am timeshifting and transforming the Ocean Preview Grid with applied Spectrum, moving it around in camera to art direct where a wave is along with its Whitewater foam cache etc. Works great, can easily take a long cache, offset it, move the whole ocean closer or farther from cam as per supervisors needs without having to resim etc. Realized at render time, simply doing the same to the Spectrum wont work. Thought to offset the Time in Spectrums but that of course just made totally new patterns in the waves. And cant move it with a Transform really can you? I am worried the only way is to bake the geo then move and offset? To be clear, I dont want to retime, or change the look or speed of the sim at all. I simply want to take the cached foam and its corresponding ocean (which works when the spectrum is baked to geo and then moved), and move it in space, and offset its cache a few 100 frames so Karma renders it correctly. Cheers!

I have a scene with 20 copies of an asset moving around,the animation its baked. There is a way to offet each copy in time? Thanks!

I am working on a simple Kine FX rig and would like to control the tail of an animal by keyframes of a single bone. The animation of the first bone should be transferred to the other bones with a time delay. I have tried to transfer the techniques shown here to my rig: https://www.tokeru.com/cgwiki/index.php?title=HoudiniChops#Stagger_and_offset_bones but unfortunately, I fail to import the channels of the rigpose Node to a Chops Network and link all the rotation values there. Does anyone have a tip for me on how best to go about this?

Happy Monday, I'm trying to figure out a way to have each line on copy to points grow as the carve animation brings in that point number for the specific copy... I was trying to transfer the attribute with color but then blending was not working very well. Any ideas or thoughts would be super helpful! Thanks in advance. growHelp01.hiplc

Hi, I'm trying to offset points along a curve with a specific p vector... I'm pretty close but it seems to be shifting the point count randomly when it animates? You can see where the problem is in the screengrab.... Here is a test scene any advice or help would be much appreciated. pointsTest03.hiplc

Hello, I'm a beginner and I'm working on a growing plant using a Lsystem. I made an animation that I exported to alembic for each leaf unfolding, but I don't know how to restart it at each Lsystem generation, so the leaf unfolds from the beginning every time. Only the first one unfolds as I wanted, logically. In the attached files you can see my node trees, the first one for the leaf animation, and the second one for the whole plant. I made a screenshot of how the animation is supposed to look on each leaf and how it currently looks. Thank you in advance for your help!

Hey All, I'm looking to create a stroke on effect with multiple lines offset in time. I found a thread here that showed a technique for offsetting animated points in a foreach loop but I wasn't able to get it working with my current set up. I believe it's because the point number is changing due to the carve sop but admittedly I don't have very much experience building something like this. Attached is a file, I'd really appreciate any help or advice. Thanks! Line_StrokeOn_v01.hiplc

Hi everyone, Can you please share your most efficient way of loading an alembic camera? I'm working with 2 alembic files (animated object and camera) and I'm trying to Object merge them in a new Geometry node so I can use the Timeshift node to offset their animations. I can see that it's working in the viewport(I'm seeing the camera and objects move at my specified time) , but I can't think of a way to look through the "camera" from the object merge. The goal is to control the time offset of many assets using 1 node. I guess I'm generally asking for the best practices while working with alembic cameras. I'm currently learning Houdini and I realize my questions can be disoriented,but any help would be appreciated, there's not much about alembic cameras in the documentation. Cheers!

Hi, just wondering if anyone could shine some light on where I am making my mistake within my pipeline? Currently just trying to make my object destroy my said geometry but its pre-breaking before contact? wondering if its because I am not using glue constraints correctly(have tried to use that way) but can't seem to think of what I am doing incorrectly? My next question is offsetting the timer, I have gone into the rdb nodes in the image below and ticked boxes around the creation frame, but it doesn't offset it as it makes it disappear from my scene until the new selected frame. Help is high appreciated as this is contributing to a final grade!!

Hello, I am currently working on an HDA, which allows me to place different objects on points using the "unreal_instance"-Attribute. Meshes and Particle Systems are placed at the right place. The problem starts with BP-Actors, they are placed without the world offset but rather at the 0/0/0 world position. Any ideas on how to fix this issue ? kind regards, Aiden Edit: it looks like it has an offset on the local X axis of around 1000 units.

Hey guys Im trying to create a similar effect to this: Ive been playing around with techniques from Entagma's 'Directions from growth' tutorial. I get the animation to play by using the following ''($F+detail('/obj/growth/data', "offset", 0))" but it doesnt give me the required results. Any help? I would like the objects to only start their rotation once they are on the edge of the transition. D

Hey magicians, I've got an alembic walk cycle cloned on a curve that I need to offset the points in order to make them look like walking forward, its probably a dumb question but I can't figure out how to offset the points. Line sop has offset so I thought I can just deform this with a noise and offset that, but how can I offset points on a hand made curve like this? Something like this Thanks!

HI Does anyone know how to make an offset mesh, to create thickness?? Also, does anyone know how to make the exterior surface of my mesh like the image? I have uploaded my hip file. scene3.hipnc

If someone would help me with this I would greatly appreciate it: 1. I have a SOP with animation on it. 2. It is instanced via the point instance technique Question: How would I offset and randomize the animation timing on each instance? Copy sop is too memory intensive and the geometry is heavy as it is.

Hi guys! So, I'm working on a project where we have to render short animation of a Mandelbulb. The Entagma tutorial worked like a charm in this case, but there is no explanation of how to do the mandelbulb animation I did some research , and I found this link, talking about how to add a phase variable, with a new function, to make the animation work. Does anyone have any idea of how to do this in vex? Here is the function: http://www.fractalforums.com/videos/3d-mandelbrot-set-phase-shift-animations/ My hipfile is attached Mandelbulb.hipnc

Hi, this formula is about offsetting animation of several objects (or points, etc.) over a period of time, in such a way that the interval of time for each object is related to number of objects and the desired period of time. Let's say you have 10 objects, and you want to animate all of them over 3 seconds, with some time offset for each object. With this formula you can change the number of objects, adjust the amount of offset or adjust the period of time, and each object will automatically adjust its start and end time, so all object animation will fit within the specified period of time. Recently, I started learning Houdini and VEX. I was curious to see the application of this formula inside Houdini. then I found this thread: http://forums.odforce.net/topic/24056-learning-vex-via-animated-gifs-bees-bombs/ in the example of Twisting Box, matt uses "smooth" function. this is what I was looking for: smooth() function in Houdini is the equivalent to ease() function in AfterEffects.

Hi everyone, I'm trying to figure out a way I can offset a keyframe by a channel value. For example, I want to animate the uniform scale on a sphere but I want to be able to control the start frame of the animation by a channel value. I'm sure there is a way you could do this in CHOPS, but I'm not very comfortable using CHOPS, and thought there must be a simpler way of doing this! Thanks in advance

Hey guys, I'm trying to replicate some UI stuff in houdini as a way to practice and learn. Here's what I got so far And here are some samples of what I'm trying to get My main question is how to offset the lines of the copy so they don't start all at the same position, I tried an attribute vop and connected the position to a random but doesn't work, I also tried the carve node and a attribute vop for the velocity but also isn't working. Lastly on the samples there are some lines that are more contrasted to others, I get a similar look with an attribute random with "alpha", but that changes the alpha of the overall circle instead of just some cut lines as the samples. As for different directons of noises, I played with noises in attribute vop and directed them by a float to vector and then a vector to float to chose if they act in x y or z, is this a good way to do this? Attached is my hip file Thanks in advice houdini ui2.hipnc

Hi All, I am taking small steps at rebuilding and improving upon some of the functionality of ESRI CityEngine within Houdini. One of the most important functions is the ability to apply 'planning setbacks' to property boundaries (see image below). From a modeling point of view this requires the ability to offset the poly from selective edges only and a way of keeping track of what each edge of the poly represents, i.e.: is the edge a street, side or rear frontage? I have been able to work out a method off applying the selective edge offsets using VEX (see attached ZIP that includes HIP and BGEO) but am struggling to find the best method of defining the edge types in a procedural way. Given this problem does anyone have suggestions for the following: Is there a way of being able to track poly edge groups in the event of the point numbers changing (points being added or removed)? Is there a way / work around to be able to procedurally defining edge groups? One of the areas most of this work is pushing me towards is the application of poly straight skeletons which is a bit daunting at the moment! I have found a really good thesis on poly skeletons here though: http://theses.gla.ac.uk/4975/ Thanks for any help you can provide! Cheers! Lot_Setbacks_Problem.zip

Hello all, I'm rather new to Houdini and this has left me scratching my head. My goal is to have a bunch of spheres moving up and down, as if they were bobbing on water. I've created a field of spheres by scattering some points onto a grid and then linking a sphere into a Copy Sop. I then stamped a variable called "bobbing" with this expression: rand($PT)*sin($F*10)/3. This makes some of my spheres move more than the others. My issue is that I can't manage to stop them from all starting this motion together and the sine curve kicks in for every one at the same time giving me the effect of a sound speaker playing. How do I get them to retain their current up-down animation while offsetting the start time? I've tried a ForEach SOP and also a Timeshift SOP but none of them worked and I'm stumped. I'd be grateful if you could offer any suggestions. I've attached the .hip file. bouncingBalls.hipnc
