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. What I want to achieve is to have the same remesh result for each object base position. My ideas was to use a rest pose, or find a VEX function that does the same as the Remesh node but I can't figure it out. Thank you for ur time

Hi everyone, I've an issue with vdb and i can"t find a way to solve this (so that's why i'm here haha) I'm working on a fluid simulation and i need to get the mesh into vdb to use it as collision surface. I'm trying to get a polygon mesh into vdb with the node vdb from polygone but there is holes and artefacts.. the issue is when i'm converting polygons into vdb with vdb from polygons there is a lot of holes into the vdb and I can't use it for my sim ( the particles goes through it). I think the problem comes from the mesh but I can't find what it is. (the mesh comes from Zbrush) I tried with a collision source node, same result as vdb from polygons. I can't find a way to get a clean vdb fron this mesh. So I wonder where those holes coming from and how can I fix it ? If someone have the solution, that will be great =D thanks a lot !

Is there a way I can change a dual mesh into a Voronoi mesh? Here's a link to a dual mesh video. Houdini Quicktip 004 Quick Dual mesh - YouTube

Hi, I want to transfer an attribute to an animated object, but I want the transfer to happen just once at frame 1 and not at every frame. Can I do that? I know that in this particular case I can simply put transform node at the end of the chain and that would be it, but I'm looking for a more universal solution. Also, can I make the 'remesh_SOP' to remesh the geometry just once, because by default it remeshes whenever any position change happens? attr_tr_q.hipnc

Hi, I'm a relatively new user so forgive me if this is a trivial problem I'm trying to sort my mesh according to regions of similar curvature. My aim is to be able to iterate over each region and remesh it smoothly— Ideally, in a way that would preserve boundary points and leave the mesh water-tight. Below is a link to the work of a Houdini artist whose procedure I'm trying to reproduce on my own meshes. Any help or a nudge in the right direction would be much appreciated. I've attached a very simple hip file illustrating what I'm trying to accomplish. Thanks so much! Measured Partitioning_test.hiplc

Hi; In Houdini, what is the best way to remesh a geometry, to achieve a clean model and edge-flow, like Remesher in Zbrush? I tried "VDB from polygon" and "GameDev Instant Meshes", but I didn't get the results I wanted. Thanks.

Hi, im trying to create a reptile scale tecnique, using points scattered along curves on a mesh where i'd like the scales, and i came across this amazing work by psop creating a chameleon.(https://cghow.com/making-of-jbl-chameleon/) Does anyone know how you can go from the first mesh which is the classic quad meshed character, to a remeshed version based on connecting all the scattered points on the mesh? i've tried everything i can think of... 1.triangulate2d, then restoring positions, but its not good for complex mesh shapes. 2.tetrahedralize, not so hot as cant tell it to only grab points from the surface of the mesh, it goes mad connecting innards of the mesh like a lattice. 3. i then tried "point iso cloud" which is great for laser scan reconstruction, and uses my custom scatter points to make the mesh BUT does not result in a mesh that uses my scatter points as the actual mesh points. 4. is there any mileage going down the vex route, creating a UV, then instead of searching for nearpoints in 3d space (where you could grab near points that arent actually connected on the same part of the surface of the character), and instead search distance on the UV positions of the points? 5.voronoi fracture the mesh using needed scale position points(scatter), then trying "compute dual" on the divide SOP. this feels quite close, i just need the mesh thats constructed by connecting the scatter points making lots of triangles; once ive got a mesh with the points of the connected triangles at the centre of my desired scale positions i can then compute the dual and HURRAH! ive been smashing my head against a wall for days now, id really appreciate some brain power as i think ive burnt all mine out!! cheers J Atomic14

Hi all, I am encountering some strange artifacts while rendering a flip sim with mantra. I applied a platinum preset material to the mesh, environment light with HDRI and rendering with Mantra. You can see the artifacts all around the edge of the splash in the video below. I smoothed the final mesh quite a bit on the particlefluidsurface and it helped a bit, but still getting serious artifacts. I also tried remeshing and subdividing as a post process to the mesh it but that introduced new problems where the mesh would look totally unstable. My guess is that it might be doing that because of the constantly changing topology of the mesh? Maybe these meshes were not designed to be rendered with anything but a fluid like shader? Is there anything I can do about it? Attached video and file (using mesh from OUT node in Mesh obj node). Thanks, Top Down Test_1.mp4 CrownSplash Anim.hiplc

Hey guys, after doing some setups in Houdini (rather new at it) I'm trying to basically "add" points into a given mesh by scattering them onto the mesh. What I'd like to do is remesh that old mesh into a new mesh which contains the newly scattered points as polygon vertices. How would I do that? Is there a SOP that divides a mesh at a given point position? Cheers & Thanks, Mo
