spline orientation after vellum simulation
Max Schwugier posted a topic in General Houdini Questions
Hello Guys, I am looking for a way to fix the orientation on the points after a vellum simulation on a spline. I want to create a rope simulation and afterwards use the sweep node to get some geo around my spline but it turns out there are some weird twists. (check pictures below) Ill att...

Hi. I have a setup with boxes scattered in a circle position. Inside rbdbulletsolver i try to use LookAt in order to force boxes always face the center while they move around. But fo some reason look at rotates all boxes. I know there must ne something with up vector but cant fiure out by myself. I...

Hi everyone, ive been using Houdini now for a few years and i absolutely love the power and the workflow with it but i am currently facing a problem which i cannot solve. the Orientation of my Grains are flipping and if I scatter stones on it, they are fliipping too. to visualize the Pr...

Hi, guys, I'm making a procedural modeling of a roller coaster. It looks very common, but I'm stuck in a problem. After I create a curve, I want to use the parallel transport method to get a smooth orientation, but I find that I do get smooth normal, tangent and bitangent, but I can't smooth th...

Is there a way to randomly orient particles on each frame? If I put down Attributerandomize node before DOPnet it gives me the same exact orientation every time particles are being emitted. I don't need that, I want completely random orientation for each particle on each frame. For some reason...

hello! I am stuck, could someone point me in the right direction? I setup some points to rotate like a rubiks cube. How can I get my instances to rotate correctly? Thanks in advance rotate.zip

Hello! I have this two models, one of them is an animated mixamo fbx of a character doing a spin-attack with a sword, and the other is a katana, the mixamo model doesn't have the sword, just the hand open like holding something. I isolated some points on the hand, got the centroid... -
Hello, Can you please help me a little bit? I would like to animate the direction of my normals based on the anti aliased flow noise in point vop. Can you tell me which nodes should I use to get this result? Thank you

Hey, I simulated low res RBD pieces and am using a transform Pieces node to apply the position / rotation back onto the highres geo. To get the orientation / pivot for the template points input of the transform pieces node I used a "dop import" node which is set to create points to represe...

Hi everyone. I have flower with of which I have isolated the stem and ran it through a simulation. I now want to reattach the head of the flower back to the stem but I obviously want the heads orientation to match with the new simulated stem. I have tried point deform but cannot get it to...

Hi guys. I have a simple sim with a tube which I steal the points from and want to instance another model onto those points. for some reason the orientation is not lining up. What am I overlooking here? shot_Coinery-Coinery_mod_Modeling_v0008_nocomment_jra_.hiplc

Hi guys, I'm currently using the Bound node as part of modelling project and am looking to store the Y rotation created by the "Oriented Bounding Box" option. Is there a way to store these values or can you create the same rotation a different way after creating the bounding box? Any ad...

Hi everyone! Let's say that I have some smoke shooting in one direction. I would like to have the orientation of the simulation container aligned to that direction to try reducing the number of unused voxels. To do that, I'm using a Point Position DOP and all is fine until I try to source...

Hello node friends! I'm diving in flocks.. I can't find any source of material to learn this besides a super old tutorial from cmiVFX. I was looking to create a bird flock, so far so good. Scatter a bunch of points, create a curl vel force and add a pop flock. The struggle I'm having has...

Hi guys, I found 2 ways to export points in maya using RF plugin and otl. https://www.sidefx.com/index.php?option=com_forum&Itemid=172&page=viewtopic&p=141806 Maya reads particles, but I can't force them to rotate. I Created rotationPP attribute in maya and assigned different vectors, for exam... -
Hi everyone. I'm hoping one of you clever people will be able to help me with this little problem I'm having. When copy-stamping objects onto some animated points, the copied objects are transformed along with the points, but they do not fully respect the rotations. I have a feeling the solu...
