Hi guys, Please refer to the image below. My goal is to have the particles move forward initially, and once they reach their destination, follow predefined curved paths with precision. Do you have any suggestions on how to achieve this effect? Thanks for helping. POP Follo...

Hi guys, Please take a look at the image below. How can I create a single primitive path, from several connected curves? Thanks for helping. Join Paths.hip

Hi guys, Please take a look at the image (and the scene file) below. I need a vector attribute on the all points scattered inside the cylinder, which be pointed (toward) to the path. Any ideas to make this? Thanks for helping. Path.hip

Hey guys, can someone please give me an idea on how create this effect? It's the one on 0:52 and 1:14 with a lot of people "flowing" around Thx

I've merged 2 skeletons together but I must have missed something because when I import to C4D the hands are in the complete wrong place in world space. Thought if I edited the path attribute it would fix the hierarchy, but it did not. Works fine in Houdini. What am I missing? RigTemp.zip

Hello ODFORCE community! First time around here and I hope you can help me with a rather simple(?) case of referencing an attribute to a node. So my situation is the following: I'm trying to feed a number of pre-made curves (from Illustrator) into a File node. In order to do so, I t...

Hey guys, Anybody knows how can I get this effect? maybe with attribute transfer? I tried doing a plane with 10-1, resample, unroll, then tried to deform the body with ray sop and with attribute transfer with no luck. Maybe with particles that flows until touchs the surface and then contin...

Hello! I need some help to understand how to use some string expressions, I'm using Redshift ROP and I want to change the render paths on some AOVs using the Custom File Prefix from each AOV. I want they will be saved on the same folder like the main output path but with other names. So, I'm us...

Hello, I asked the exact same question in the official houdini forum and got no answer yet, hope that's no problem I'm trying to make an object follow a path created from points (positions imported from an external file) with a velocity based on the distance of subsequent points. I used the...

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. A...

I have an object merge inside a sop solver that is inside an rbd sim. The object merge is pointing to the Geometry in the rbd object from the sim. with: ../..:rbdobject/Geometry Why does this work with the colon? why isn't it another forward slash. ../../rbdobject/Geometry I understan...

Hey guys, I need to send a large point cloud which instances geo to the cloud to render. The problem I'm having is the instancefile attribute is absolute, and once the project is uploaded to the cloud render environment the path is no longer relevant/correct. Redshift does not seem to expa... -
Hi, Is it possible to change the the preset location to a server location or shared folder. So you can share it with colleagues? I found some on the forum to save them in otl's. But it would be easier to share a folder and direct to it? How is this problem solved in big studio's? Th...

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...

Hi guys, I'm trying to write a light path expression that excludes the default custom bsdf label "coat" To have only the coat layer is: lpe:C<...'coat'>.* To have all reflections but the coat I would expect it to be: lpe:C<RG[^...'coat']>.* This gives a syntax error and do... -
Hello, I am trying to set the path of the current scene viewport via a button press from a hda. I know these python docs below are the key, but I can't seem to tie the relevant python functions together. https://www.sidefx.com/docs/houdini/hom/hou/PaneTab.html https://www.sidefx...

Hey Everyone, i'm hoping someone could help me with this problem. In a nutshell, i need to move smoke down an animated path, so that it sticks really tightly to the paths animation, but with all the dynamism a smoke sim brings to the table, i.e. nice peeling away around all the edges etc...

Hey guys, Pretty new to Houdini after many years of Maya. I'm importing an alembic and want to push the path attribute all the way to the end to retain the original hierarchy. When I add a voronoi fracture only the inside group seems to maintain the path attribute. The outside group and my...

Hello I am want to translate a bulge along a curve path . i have used "follow path" to move the metaball along the curve... but as soon as use the metaball as my "bulge magnet", it wont follow the curve anymore. What am i doing wrong? Any help is welcome! (in fact , it would...

Hello, excuse my noobness, but i am looking for a way to translate a bulge along a curve path to deform a tube. I have a tube and my curve, i add a metaball, to which i add a "follow path" constraint. The metaball moves along the path as i advance the timeline. then comes the time i s...

I'm trying to get the full path to the parent node in the current paneTab under the users mouse. I'm currently doing the following to return the paneTab: pane = hou.ui.paneTabUnderCursor() I can get the current parent node with: pane.pwd() So if i'm in /obj/geo1/subnet1 th...

Hey Forum! I have a path that runs from one point to another point in a surface volume. This is a volume that I have converted into polygons. Pictured here as the black line: How might I create a geometry that takes the top surface above the line, the bottom surface below th...

Hi guys, im new to houdini. Im following a tutorial by entagma on how to make a growth sim: https://vimeo.com/197596529 . I exported it as alembic file and imported to cinema4d, and my results look somthing like this: https://imgur.com/a/M1UgW My growth sim for some reason is flickering. I...

Hi all, I tried to edit my DSO path as shown in the HDK guide, but it didn't work properly. Worse, now when I launch Houdini, all my plugins are broken! I've realized I don't need to move my DSO path yet, is there any way to reset the DSO path? This is on Mac OS X. Here is my output from h...
