Hello all, Maybe a dumb thing, but I can't figure it out right now. I rebuild a simple setup to understand the issue (you will find the file attached) I have a simple wall that I want to break (RBD SOP) I created a sphere emitter on the other side, with RBD bullet solvers too (RBD SOP)...

hi all i'm trying to work up an rbd sim for some ground fracturing. I have an object colliding with the geo and transferring colour to it. Now in the scene (included) i have a setup that is NON-dopnet based... just using a point deform to shift the pieces - its kinda cool But i wondered i...

https://ibb.co/Y2N8z8B Made a grid to use its points as your particle sources connected a pop net to it In the pop net i mainly edited the POP Source Source Tab: changed geometry source to "use first Context Geometry" to use grid points as sources... -
Hello! I'm following this tutorial: and have been getting similar results up until around 22:10, when my simulation behaves entirely differently. My worm just goes flying. I've messed around with the values in the set_force attribute wrangle inside the sop solver, but can't seem to...

I'm leaving this file here in case you want to sort the point order of a triangle sphere. Its not particularly usefull but I was tasked with that challange and thats what I came up with... Hope it helps, and if any of you has a better method feel free to share! sorting_a_triangle_sphere....

Getting closer to a new surreal idea I had in mind for a long time...Walls with Eyes! Here is my initial test for a small section of the wall. hoping to add in more detail and deformations to the rig the wall skin rig. I made the entire model and rig process combined into a single HDA. May need to o...

LookAt Setup in SOPs, VEX, VOPs. Having used the Houdini default tools several times, I wanted to achieve the same effect in SOPs. Here is a detailed post to understand better how the LookAt works and how it can be used in creative ways https://www.sharanvaswani.com/single-post/2020/09/27/Using-VEX-...

Hello dear people of the force. In lops: I have been trying to set up a simulation that takes existing point instances and then modifies them with a dop inside a sopnetwork. I have been looking at the drop node to try and kitbash a solution. I keep on having the problem that it jus...

Hey all. Just posting a new tool I recently wrote in case anyone is interested. It's an HDA for saving attributes into either data textures or mesh vertex channels for use in realtime shaders. I needed to do some fancy pivot caching and mograph type stuff in a Unity shader and after h... -
Hi. I am testing FLIP sop, in particular "flip configure lava". As a temperature input "anoise" was used. I would like to animate it but when you animate anything outside the solver it is obviously not updated within a sim. If I were about to make it with dop network I could have make a wrangle with...

I start to learn the new sop fluid workflow, but there is no uv data on final output mesh. How can i keep uv from the beginer model to final fluid mesh? fluid-test.hip

Hello, I have a tube, I want to animate the radius scale. So that it expands and shrinks randomly. I want it to look like it's being animated by a noise. My problem is that I don't know how access the radscale in the tube geo. Thanks!

Create point group which are not connected
Apurba Haldar posted a topic in General Houdini Questions
How create point group which are not connected. like the ss below?

Hi! I wanted to know if there is a way to extrude points to generate curves from that extrusion, I was surprised that the Extrude SOP didn't accepted that kind of operation. I had a workaround for doing this using the "Copy to points" SOP to copy the input points (the ones that will sweep troug...

Hello, Trying to work with RBD bullet solver and conetwistconstraint, but I found a limitation in SOP Bullet solver, cause it has only one conetwistconstraint settings, and in case if I have more than one conetwist constraint it become a problem. I tried to add it inside solver but have no succ...

Hello For a cloth set up I need to have the same remesh (via Remesh SOP node) result of an object on each shot. The object to remesh is the same in all shots, but is Position change. I can not dive in the Remesh node but it seems that while translating an object, is remesh result change.... -
Hi all, Is there a way I can use a shelf tool python script to select a joint in the rig tree window pane when I have a rig pose SOP selected? -
Hey, bit of a specific use case here, but has anyone successfully used the .asCode() Python function with the SOP solver? I can't seem to get it to save and recreate the nodes inside of the sop level solver node. I spent some time researching it but haven't found anyone even mentioning this problem....

Hello, I'm han. I have a question. I did Sphere -> Mountain(noise animated) -> Scatter & Sphere -> Mountain(noise animated) =Points and Sphere Merge (*so I want to sphere moving and scatter points are also moving) but Scatter points are jittering(not...

I've laid out UV's procedurally in Houdini with the sweep or skin sop and using arclen on the input curves, but I'm wondering if there is a solution to straighten/unwrap geometry that is generated in ways other that using a sweep or skin SOP. If anyone is familiar with the Unfold Strip from Lo...

Hi everyone, Anyone knows how I could get the world position of the tip of a bend deformer handle? (see image)

Hey everyone! This is my first post here! I have a scene where I'm caching a vellum grains simulation to a disk cache. I'm having trouble understanding why it takes so long. When I cache the simulation to ram in the viewport each frame takes about 15 seconds, however when I drop a File Cache SO...

Hi. Im trying to make a growth setup. The simulation is too fast for me. I try to increase the FPS but didnt work. I also try the Retime sop but didnt work too. How can i make slower version a Solver Sop simulation? Thanks. 002.hip
