  1. Wiggling Fur

    Hi all, I created a vellum fur simulation for my chimpanzee that simulates the guides perfectly. But when I render, the actual fur, especially the longer hairs, are wiggling like crazy. It is especially noticeable thanks to the white hairs I have. As far as I know, I have no wind forces activated. I've looked around and tried many different renders with different sim parameters but the same always happens. If anyone could take a look I'd be grateful. I'm attaching the project with some renders so you can see the problem. I deleted things like textures and sim cache to keep the file size smaller, creating the cache is quite quick anyway. If anyone has any questions about the setup just let me know. Thanks in advance ~Tomas
  2. Hi everyone, my name is Tomás and I'm new to the forum. I'm creating a fur sim for a chimpanzee using the Guide Simulate node with the Vellum solver. The chimpanzee will later be animated. The sim works fine but I can't find a way to make it keep its wild messy look. The guides do keep their shape (bend, guideinit, etc) because I increased the constraint iterations and the bend stiffness. But I can't find a way to make the hairs keep their direction. In other words, once the gravity affects the guides they all go too down. So I want a way to keep the original shape of the hair a bit more. I could tone down gravity or the mass of the guides but that would make it look as if it's underwater or something once I animate the chimpanzee. Increasing the constraint iterations to a ridiculous value would maybe fix this but at a high cost to sim time, same for stubsteps. Increasing Bend Stiffness to billions and billions doesn't seem to help either. Obviously, I don't want the hair to be hard as rock. I want it to behave this way because it's light, strong and covered in dust and sweat, if that makes sense. It's also important to note I committed the noobie mistake of not resizing my mesh after exporting from Maya which works with different centimeters instead of meters. Meaning my monkey was more than 100 meters tall. I believe I already fixed this by going to preferences>Hip file options but I did this after creating the simulation so I'm not entirely sure if everything was resized correctly. Attached are 5 images: the guides at frame 1, the guides at frame 73 (3 seconds into the sim), a render of the fur at frame 1 (the way I like it), a render of the fur at frame 73 (the way I dislike it) and a reference image for the sort of hair I'm aiming for. I also added the project folder. ApeODForce.zip Thanks in advance!
  3. Hello! My name is Joyce Kambey. Currently reside in Singapore, and looking for a job. Will be graduating from 3dsense Media School (VFX Specialisation) in 1 week. Before I came to 3dsense I have 3 years production experience as character rigger and 3d animator. I have used houdini for rigging & animation works for almost 3 years, and used houdini for FX works for 8 months. I have attached my resume with this topic. here's my demoreel: links: linkedin: https://www.linkedin.com/in/joycekambey/ vimeo: https://vimeo.com/joycekambey artstation : https://www.artstation.com/joycekambey e-mail : joyce.kambey@gmail.com JoyceKambeyResume2019.pdf
  4. 1) Is there a way to only affect the tip of your guide curves when using the groom brush? It’s easy to grab the center of the guide curve which ends up bending them in an odd way that’s counter to the direction I’m attempting to brush the curves in. If I make my brush small enough and position my camera strategically I can of course just graze the very top of the curve but it becomes difficult when there’s a lot of guide hairs. Additionally, If I use the curve advect tool I notice that all of the guide curves that have been advected have a concave bend to them similar to if I had used the screen brush on the center of the curve instead of the tip as I mentioned above. 2) Is there a way to pop hairs out that have flipped through the other side of the surface? If I do a simple fur setup on a grid it’s very easy for this to happen with a few strokes of the screen brush. 3) Are there recommended ways to optimize the viewport when grooming? It seems really sluggish even with a modest amount of guide hairs once you start adding a few guide process nodes. My hair generate node is off of course. 4) After I place a guide groom node and use the plant guides tool to create a few custom guides the guide groom density no longer has an effect if a raise or lower the value. If I disable the planted guides, it works again. Actually I’m realizing now that even doing a groom with the screen brush seems to lock that initial guide count into place. Is this the intended behavior? 5) When using the Hair Clump node it seems like mixing the blend value to 0 doesn’t actually turn the effect off entirely. With default settings and blend set to 0 I still see very obvious clumping. It’s not until I set the fractal clumping iterations to 0 does it act as if I disabled the node entirely. With fractal clumping set to 0 and the blend set back to 1 though, the settings in the general tab (clump size, crossover rate, etc) do absolutely nothing. 6) Is there a trick to setting the influence radius and decay values in relation to both the guide curve and hair generation density? It seems heavily dependent upon how many guide curves I have of course but I’m finding that’s easy for me to end up with a look that’s too clump-y without actually having a clump node in my setup. If I raise the influence radius higher to move away from the clump-y look it starts to lose any variation I may have added to length, bend and frizz. If I come up with something that's look pretty promising with a low hair generation density I'm usually surprised at how different feeling it looks once I start to really crank the density values. Cheers!
  5. H17 Fur query

    Hi, Beginner query around hair & fur. Whilst I jumped in a had a quick look at the fur tools, I've got a little confused with SideFX help example referring to the 'Fur' node, which doesn't appear to be part of the workflow (especially from the shelf tools). This link suggests even in H17 it creates a 'Fur' node, which it doesn't for me, instead clump etc are their own node. http://www.sidefx.com/docs/houdini/fur/hairstyle_rasta.html Can anyone confirm the 'Fur' node is not used in preference for the Hair Generate? Thanks.
  6. Rotate clumps?

    Hi ! I'm trying to rotate clumps using vex, I'm new into Houdini closest I could get is using this vex code from konstantin magnus on "how to rotate faces along Normal?" topic, but the clump rotates on the wrong axis =( I want achieve the results in this video at 17:32 (Hair FX in Houdini - GDC 2017 Talk) where Saber Jlassi does some really great twists on the clumps. https://vimeo.com/sabervfx/hairfx#t=1054s Here is the file scene !

  8. I've got an R&D file in which it looks like the hair count is changing frame-to-frame. Both Mantra and Redshift are identifying the topology as changing frame-to-frame, so they're both disabling deformation motion blue for the object. This occurs whether the both the guides and the hair are cached or not. Is there a necessary rest setup for hair/fur? I've gone through the nodes in my set and the rest cache option under Static Generation on the Hair Generation node is about the only thing I see that might come into play. Attached are a few images showing the issue between frames 30 and 32, as well as the scene. – mC FurBall_ForRS_01.hiplc

  10. Flatness Effect for Fur Clump

    Hi ! TL;DR: I'm trying to reproduce a XGen Clumping modifier called Flatness Effect into Houdini Hair. It Flatten the clumps. Instead of the usual cone shape of a clump, basic its makes it flat like a mohawk hairstyle on top of every clump. ... I want to migrate from Maya Xgen to Houdini, but the only effect I can't reproduce for grooming is this flatness effect, and I do use it a lot! I tried all the Guide Process nodes and Set Direction was my best try, but I still can't make it work. Probably doing something to Parameter:Tightness inside Clump to move only in one plane the clump would work ? But how to do that? Please help !

  14. Ideas to achieve this effect

    Hi im learning houdini and a few days ago I found this and I really wanted to create something like it using Houdini, the problem is that I don't really found a way to do it and I'm kinda frustrated, my first idea was to scatter points on the base geometry and then copy to points a grid, but then I'm not sure if that could work or how to make a cloth sim for the grid which should be colliding with each other, idk maybe is easier that I think and im completely in the wrong path haha if someone can guide me a little bit on this little quest ill be beyond grateful. .

  16. Hair with soft body sim

    Hi guys! I have been trying to figure out how to re-create this effect. https://www.instagram.com/p/BiMSgmaHHQT/?hl=en&taken-by=hellompc I have a few questions as to how I should go about this 1)Would I simulate the soft body first followed by the hair or simulate both of them together? 2)Using the simulate guide shelf tool,it creates a separate network that is not part of the autodop that the organic mass shelf tool creates, Thank you!
  17.

  20. Deform Groom curve stretching

    Hi Odforcers, Im working on a project where I have to tear up a lawn using bullet rbd's and hair to generate grass. Ive come into a problem, or maybe a bug where the grass in the deforming rbd patches becomes very long either when moving through space, or even at rest. I cant seem to find any other topic where this has happened before. Has anybody encountered this kind of problem with H16's hair and deform groom? Any incite would be appreciated. Id love to attach a screen shot however the content is under NDA. All I can say is imagine a bunch of curves spidering out from underneath a few selected skin patches. Cheers!
  21. Fur Sim Issues with Scale and Settings H16

    Hello, Using the latest version of Houdini 16.0.736. What is best scale to simulate fur on female jacket. Should I simulate real-world scale or scale it up very large for better fur simulation performance? For Example, should the fur coat match the scale of the test geometry like rubber toy or pig head? Should it be scaled to 2 meters or 200? I want to master the scale before tinkering with the Fur Sim settings. Otherwise, does anyone have dynamite fur sim settings for a specific scale? My sims either seem very static or dramatically broken with stretching fur. Thank you, Ryan
  22. Hi FX friends, In previous versions of Houdini the hair/fur tools gave you the ability to generate guard hairs and white hairs, however with the new toolset I can't seem to find how to generate these hairs. I've searched through all shelf tools, guide/hair generation SOP's, the Houdini 16 hair masterclass and the Houdini 16 documentation to no avail. Perhaps there's a new workflow using creative grouping of guide hairs and throwing them into a whitehair/guardhair attribute I'm not aware of? The new Hair shader seems ready and willing to pick up such attributes so I'm really scratching my head here. Any help and direction would be greatly appreciated! Thanks!
  23. Hi All, I am not sure I am posting this in the correct Forum segment..if note please let me know. For the life of me I cannot find a way to replace/control the hair shapes from ribbon to cubes or hexagons and etc..... Trying to achieve in the images below using Hair and Fur as it is much faster than using the Copy stamp Sop. I have tried Polywire (super slow) and I was using the Hair shelve tools. So created a Geometry Node with object merge using the output of the Hairs ====> Polywire. Any suggestions would be great The below is the result achieved so far....super fast performance Cheers!
  24. Houdini 16 hair parting

    Hello, Does anyone know how to use a guidepartition sop in the new hair tools? It seems to do pretty much nothing visually by itself. I managed to use the partdir attribute to set a direction of the guides with the guideprocess sop, transfering this attrubite to the skin at first. But maybe there's a right way of using the guidepartition? Thanks.
