  1. UVs to polys from VDB showing distorted seams

    I found a solution, the voxel size is the answer.
  2. Hello, I'm trying to figure out this thing about UVs and polygons from vdb in Houdini and so far so good except for the new and nasty UV seams that are created after the transfer is done through attribute from volume. Maybe someone can shed a light on this, it would be much appreciated. So, i created a simple scene with the pig head, converted it to vdb (from polygons) and then back to polygons. My intention is to transfer the UVs from the original head to the converted polygons from vdb, just for studying purposes. I used the attribute from volume node and it worked almost great, the UVs are transferred nicely but with nasty distorted seams. Even though the UV seams get lost in the vdb conversion, the approximation performed by the attribute from volume node is quite good but i cannot imagine a solution to solve the distortion on the seams, at least through this approach. The attached images show the comparison between the original UVs and the transferred UVs to the converted polys from vdb. Any idea about how to clean the erratic distortion on the seams? Or, is it even possible to do such thing? Thanks.

    Hi all, Here is a quick doodle in Houdini + Redshift + DAZ. Any comments are welcome. Cheers.
  4. Cannot see second HD inside Houdini

    Hey @lukeiamyourfather , thanks for your answer. I figured out what happened and it was easier than i thought. So in Linux, the secondary/external hard drive is mounted under the "Devices" and "Media" folder structures. The "Media" one is the catch. Inside Houdini, i just had to point the project file structure to "Root(/)/Home/Media/UserName" and there it is. The HD shows as it should. Cheers
  5. Ubuntu 18.04 LTS "Bionic Beaver"

    Last weekend, i installed Kubuntu18.04, Houdini 16.5.496 and Redshift 2.6.11 and everything is working fine so far. Even though, the ALT+LMB function in Houdini like rotating the viewport while changing camera position with gizmo on doesn't quite work. That is because the ALT+LMB key combo is used globally by the OS to move app windows anywhere you want without having to click on the top bar first, which is cool and it is not. Other than that, i also noticed that once i have Houdini and Redshift running on the background and start jumping around apps like firefox, dolphin, calculator etc. the system freezes. Not all the time but it happens once in a while. After 2 days of research, a posslble reason for this OS behaviour could be the fact that if there is only one GPU card installed in the machine, which is my case, the card gets overloaded with CUDA calculations (Redshift) and OpenGL renderization of Houdini viewport and OS environment. This type of situation has been observed across OSs, not only Linux. So the recommendation to solve this problem is to install at least 2 GPU cards in the machine if the intention is to use GPU renderers. Lucky you Mantra users. My system config is: i7 8700K (4.6ghz OC) 64gb RAM 1 250gb SSD / 1 1TB SATA nVidia GTX1080ti Kubuntu 18.04 and Win10 I also had an issue while licensing Redshift in Kubuntu18.04 due to a library package that didn't come with the OS (libpng12). Without this license, the Redshift licensing tool doesn't work. It took me a good day of cursing to figure out how to solve the problem, download the library manually from the Ubuntu website and then install it in Linux. Hope this info helps. Good luck explorers.
  6. Hello, I just installed Linux Kubuntu18.04 and so far, everything is going well in Houdini. However, all my 3D files are on a secondary internal hard drive and i can't see it inside Houdini. In Linux, i can see it normally in the "Devices" section. How can i make the second HD visible inside Houdini? Thanks.
  7. Which Nvidia driver are people running?

    I'm on Kubuntu18.04, GTX1080ti running nvidia-driver-390
  8. How to create voronoi curved surface (no inside group)

    Yea it does work! Your group expression solution is neat. Nothing like some quick coding. Thanks!
  9. How to create voronoi curved surface (no inside group)

    Yea, that is a solid solution! Thanks man. One question, how come the inset in the poly extrude sop doesn't work?
  10. How to create voronoi curved surface (no inside group)

    Thanks for pointing it out. I saw some stuff that Junichiro has posted, he's offering great tutorials for the community. On his voronoi tutorial, he points exactly how to use code to clean the edge points and create new polys, exactly what i was curious about. My approach to this problem was creating a new poly from scratch with no divisions, scatter points to it, connect to the voronoi fracture, use fuse sop with increased distance and then connect to ray sop. It works but there is definitely some extra work to do with complex shapes. Junichiro's approach is much more bullet prooff
  11. How to create voronoi curved surface (no inside group)

    Hey Noobini, Thanks for your reply. So, the intention for the project is not creating any rigid body simulation or anything exploding... i only need to create a surface with the voronoi cells that are clean and connected so i can later manipulate the cells adding poly extrude, for loop etc.... Checking your file, i see that you fused all the cells as i already tried but there are still vertices along the cells edges making them not usable for later manipulation. I haven't tried using the exploded view sop because i want the inverse of exploding the cells which is connected cells, no need for it... I wonder why the voronoi fracture sop automatically disconnects the cells, maybe because the sidefx folks thought about it only for sims? Keeping the original edges from the previous geometry state is great for sims but would be interesting having some options within the sop to remove original edges and connect the cells. I'm sure that there are ways to implement this through VEX but i'm not fully versed in VEX yet. I hope that in the future versions of Houdini, SideFX can take a look at the voronoi fracture sop and add some more options to it. Cheers
  12. How to create voronoi curved surface (no inside group)

    Hi Alejandro, Thanks for your input. For this project, i have to create a geometry instead of renders only. I'm trying to extract the voronoi cells from the original mesh edges, as they are mixed in the result and then fuse the vertices of the isolated voronoise cells. I haven't reached that result yet. When i turn on the vertex display, i can see that the voronoi fracture sop creates vertices along the cells edges and i suspect that those are the reason why i cannot fuse them. Ant steps towards the goal.... Thanks!
  13. Hi, I have a simple question but after hours researching i couldn't find an answer yet..... i'm trying to create a voronoi curved surface but after trying this approach: voronoi fracture/blast-inside group/divide-remove shared edges i get the voronoi cells on the curved surface but each cell is disconnected. I also tried tweaking the "fuse" setting in the voronoi sop to connect all the cells and add a fuse sop in the end but for some reason the cells vertex never get fused. Does someone knows how to create a voronoi curved surface without those straight edges from the original geo? I'm attaching some images as references to i i'm looking for as the end result. Any help is appreciated. Cheers
  14. Configuring $HIP and a project directory.

    I think the easiest way, not taking the credibility of setting up the Houdini environment file, is to copy the path location where the new project folder will be placed then go to File/New Project, copy the path there, create a new name for the new project folder and hit accept. Pretty simple. Pre-Flight Scene is also very handy for that kind of stuff.
  15. Sine waves color

    Oh man! The master himself! Matt, thank you so much for the amazing material that you posted a few weeks ago in your website. Learning a lot with it! Some challenging exercises but i suppose that programming is supposed to make people think smart before implementing it. We should have a section in the odforce forum dedicated to the Joy of Vex. I bet that a lot of people have questions about the exercises. Thanks for your help on my question. "Lerp" is a good friend. Cheers.
