  1. paint density

    hi guys i use paint node to get particular scatter points for my object but when i fracture it, pieces look so long i guess it is a density problem. i just want irregular pieces but more points in some areas.how can i fix it.please help me... test.hipnc
  2. CAMP_2016_Behind_The_Scenes_on_626475235.mp4 Very nice piece in my opinion by Raw & Rendered! Inspiring. I believe the technique is related to curl noise and many examples I found in this forum. However, I am particular interested in this setup where the curl noise is actually controlled by guide curves/circles. Also interested in how the spheres are randomly scattered on the curves and flows with the motion. I have attached the actual references for the frames. I am very new to Houdini and love procedural. Have been experimenting with wrangler nodes, sops, vops and etc. It would be great if anyone could share the approach on creating a piece like this. Looking forward to your input.

  3. VORONOI & REM -ADD FRACTURE POINTS

    Hello! I would like to know how you could control how your voronoi or fem will break. I used to watch videos by Sangiemenla, he explained how to use the "add" node to control where your solid would be fractured. But now I can't find his channel any more and I can't remember! I would also like to know if there is a similar way for FEM network, to set where the solid object will break. Thank you! Antonin
  4. FEM Fracture Attribute

    Hello! In this Masterclass, at 41:00, the teacher explains that fracture parts of the object can be localy modified using an attribute. So my question is about this : how do you control what part of the object will fracture? is there a way to connect the FEM solver to a voronoi attribute or anything like that? Thank you for your time!
  5. Hey guys. I'm pretty new to the houdini world, and I've been experimenting a lot of things. Is there a way to get the RGB values of scattered points using attrib wrangle? Im not too familiar with the VEX syntax, so Im having a hard time figuring it out. I have random colours signed to a scatter node and some geometry copied on to the points using a copy node. I want to limit scatter the geometry based on the colour of the scattered point. Thanks!
  6. Hi, I have been trying to deform scatter point over the surface of the geometry, What would be the way to deform or slide scatter or give slide scatter points with offset over time on the surface of the geometry ? I have tried with color texture and it worked, but i am looking forward for the VOP method, can someone guide me over that ? I am still to houdini and trying things out. Thank you,
  7. I am trying to scatter some points on a circle. But I want the points to be scattered more near the center and less towards the outer side. In the old Houdini Scatter I could do it by making my Circle Primitive type to "Polygon" and then uncheck "Divide Non- Convex Polygon" on the scatter node. However, in the new scatter node of Houdini 14 and 15, this option is not available. Here is what I am trying to achieve, this is with the old scatter node. This is what I am getting with the new scatter node. Please help.
  8. HOUDINI - Alembic and RBD (Beginer)

    Hi! I'm starting with Houdini, and I would like to know how to combine a cached animation and Houdini's RBD. I know that this question has already been asked on this forum, but as I said, I am a beginer, and I would need reaaaaly basics answers. (I don't know any one who uses Houdini so sometimes I have simple problems that I can not solve). So my problem would be : - I receive an animation made with maya. I export an alembic (or a cache, FBX? Is there a best way?). I import it into Houdini. -The animation works, but when I set it as a RBD solver (or FEM, or anything that has something to do with gravity), the animation doesn't work any more. -I heard on this forum about a RBD keyframe node, about "Use geometry Transform", but I'm really too new to be able to use these informations. For exemple, if I want to use this alembic (attached file) : it is a little sword, I want it to be breakable, and to keep its animation. How would you do this? I hope somebody will find the time to answer to my questions, thank you! petite epee.abc
  9. Hi, I create a new project but have a new problem. use to source object its has not problem but when added the point on source objects its changing rotation. I hope, you can help me for ı can fix my files.
  10. Hello everyone ! I have some trouble with the foreach loop, and after some search I have not found an answer... I want to connect points from two scatters and do some operation on each pair of points : connect them to a line, resample, noise and set pscale depending of point number of each loop. Here is what I have : A scatter "A" creates two points. For each of thoses points I want to scatter (with scatter "B") another point and connect them together. Here is my two issues : 1- I don't know how to scatter from a sop outside the foreach loop. 2- I connect my points using the add sop setted to "Polygons > By Pattern > Polygon 0 > 0-$N". Will it work on the second iteration ? Here is an image of my network : Thanks for helping ! scatterForEach.hipnc
  11. Hi, I'm facing a pipeline issue: I'd like to scatter dozens of object in maya using the houdini engine. It's working fine if I scatter a simple object like a torus. BUT in order to keep my scene light I would like to scatter arnold .ass file. But houdini engine doesn't recognize ass files. Do you know how i could avoid that, or maybe use Htoa.. The point is to be able to scatter and control a huge amount of object without getting a heavy scene thanks
  12. Letterpress

    Hi, here's my first project using Houdini. My goal was to get in touch with Houdini by transforming skin to metallic letters. I wouldn't have been able to realize this effect without your help here on the forum. Thanks a lot! dk
  13. Hi, I'm trying to scatter points onto a surface provided from maya and imported as alembic geometry. To get the result I need, I have to convert the outside geo into a curve and then use a polywire to outline the geometry. Afterwards I need to scatter points into the polywire. However using the rest at frame 1 and then attribute interpolating the points onto the surface I still get twitchy points. Is there another way to do this where the points are static and moving with the polywire? Is there something I missed. I am not using a rest node, I am simply freezing the points on frame one. Thanks in advance.
  14. Hi Houdini 14/15 scatter node is slightly different to 13. I understand there was a thread about this talking about the Attribute Bias option but what if you're scattering points within your geo/volume and not on the surface. https://www.sidefx.com/index.php?option=com_forum&Itemid=172&page=viewtopic&t=37345&highlight=&sid=7851375fa44ef5f63c8fa9aa751b4cfe It used to be you IsoOffset and the Scatter node would pick up on it. Any ideas? EDIT: Point Jitter does have some use but does have its limitations
  15. Hello world! I'm working on a school project which consists in a gun bullet going through a robot helmet. The modelling and animation has been made in Maya and exported as an alembic. I imported this alembic into Houdini and separated each object of the scene with the Pick option. I added a Scatter node and a Voronoi node on the part of the helmet I want to break. Then I did all the RBD stuff and the destruction works fine except I have a very annoying problem: the shatters of the helmet are too visible. Some screenshots to help you understand: Frame 1 (notice the shatters on the opposite side) Frame 34 (after impact) I'm a noob on Houdini so I might need precise explanations! I've been stuck on this for days and I'm getting desesperate... Thanks in advance for your help!
  16. Hello, I'm having a problem with a setup I'm trying out and I'm hoping someone might have some ideas on what I can do? I'm creating this 'archway' that's made out of spinning blocks. The blocks are moving along the path of the archway. (At home right now, I'll put an explanatory pic up when I'm back at work tomorrow.) For this animation the archway is constantly changing it's shape. To acheive this whole look, I have about 6 nulls which I animate the positions of. Then -create a closed curve through all the nulls. -carve along the curve (this is what makes the cubes travel along the path) -resample the curve -sweep and skin a circle along the curve to create a tube -scatter points on the tube -copy boxes to all these points. This works reasonably except when the curve changes length and then the scatter sop ( or maybe the point numbering of the tube ) changes and all the boxes jump to different parts of the curve. I'm not sure what to do about this. My current idea is to try and keep the length of the curve constant. -Two of the nulls and the bottom part of the curve are off camera. I am thinking I could use a measure sop and a Python expression to iteratively reposition these two off-camera nulls to maintain a constant length. I've had a go, but my Python in Houdini is pretty beginner and I'm not having any luck yet. Any suggestions? Simeon.
  17. Hi, Try to use voronoi fracture in Houdini 12.5 but my scatter doesn't pick up my red color while im using Cd at bias 1 anyone?
