  1. I am trying to create a solid object, with hair simulation that can collide with other surfaces. Right now I am using the "Organic mass" shelf tool, to create a solid object of a sphere. I am then applying hair (Add fur) and then adding hair simulation (Also via the shelf tool) I have also added a ground plane. When the solid object collides with the ground plane (And the object begins to deform), the hair simulation explodes. Is there another way to create a solid object with hair simulation, that will work, when colliding with other objects?

  3. Htoa Hair Problem

    Hi, I made Hairs in Houdini 16.0.557, I made a Hair Standard (Arnold) material where I used Ramp in "V" for color along hair strand. It works in Htoa 2.0.0 (Arnold 5.0.0.1) , unfortunately I have to render this on farm with Htoa 2.0.1 (Arnold 5.0.0.2) and this is not working anymore, it looks like it taking the source geo for hair and colouring whole hairs. (I have kind of strips on these hair strands) - not any more on Htoa 2.0.1 Any Help? Or some workaround? Thanks. B
  4. 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!
  5. Hair effect? (flow/er)

    Hey magicians, I'm trying to study an effect I saw on flow/er by Lukas Vojir: Here are my thoughts about it: 1) Make curl trails and convert them to hair somehow to get that movement? or wires? 2) Create simple flip with curl noise and advect trails? So far I run some tests, I can get a similar result in static, but I cant give that movement, it is possible to convert advected trails to hair/wires to get that? or there is another better approach? Thanks in advance Cheers!
  6. Hello everyone. I am trying to follow the gdc 2017 talk about hair game creation and I can´t find the way to isolate the three curves that belongs to each primitive inside a for each loop. In side the for each loop I have the primitive and in the talk he create and attribute call curve id and in base to this attribute blasted each line that belongs to the primitive with a point expression. If someone could help will be really appreciated. Thank in advance. Isolate_curves_foreach.hiplc

  9. 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!
  10. Hi all, I am attempting to render out hair curves and only have them generate at the time of render. As I understand it, setting the hairgen node (created from a fresh scene from the shelf on a rubber toy object) render parameter to Hair Generation = "Generate Geometry in Mantra" is supposed to do just that. If I switch that parameter to "Use SOP Geometry", the hair renders out fine, but that defeats the purpose of not writing out the geometry beforehand and thus bloating the size of my IFDs. Otherwise none of the hair renders. Has anyone seen this happen or know what needs to be changed in the scene? Is this a bug? This is using HoudiniFX, v16.0.619 I cannot supply my scene file, nor screenshots, but this is happening in both my actual scene file and in a fresh launch of houdini with simple geometry as the only geo in the scene.
  11. Hello all, I wanted to share a Houdini OTL asset I've made and am testing out for the beta release: "https://www.psynema.com/houdini-procedural-hair-cards-game-meshes/" The link above is the documentation and download links (available on Orbolt) The asset takes Houdini's Hair system, then procedurally makes a low poly hair card for each hair clump, so your hair generate nodes will need a hairclump node within to initialize a clumpid attribute. Simply plug your hair generate node into the asset and the left output will give you a low poly hair card wig and the right output gives you a high poly mesh that's exportable. (Houdini's hair system is actually NOT geometry that's exportable to other software, so the asset takes care of converting it). MORE IMPORTANTLY - the asset procedurally creates a GROUP NAME for each hair card that MATCHES its high poly hair clump. That's important because Substance Designer can take that information and BAKE EACH HAIR CARD SEPARATELY without interference from other hairs belonging to other cards, something Houdini has yet to implement, a "match by mesh name" feature. Let me know what you all think as I'd like to build upon the asset. Thanks, Gary
  12. 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!
  13. Two questions about hair: 1) I'm trying to get a "helmet hair" look, i.e. a hairdo that has been "pushed" closer to the scalp. I can always modify the guide curves by manipulating them as SOP curves, but I'm wondering if there's an dedicated groom (either tool or process) that would push an existing hairdo closer to the scalp. Or should I perhaps start with guide hairs that are already near-tangent to the scalp and try to create the "helmet hair" look from there? 2) While working on the problem above, I often get hair penetrating the scalp. Is there any setting in the groom tools that would force hair to always stay outside of the scalp (without doing simulations)?
  14. 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!
  15. 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.
  16. Hello,I have 2 questions about the hair:1. When I paint the density attribute the hair guides are reacting based on the vertices, i.e. when I hit only a vertex guides disappear (or appear). It means that with low polygon count I can't avoid stepped guides boundary. But with more subdivisions it is practically impossible to work due to long cooktime after each brush stroke… How can I deal with the guides between the vertices without increasing subdivision? Attachment below describes it.2. To delete hair guides (for example, for hairline or beardline on the head) I use Length Adjust shelf tool with Target Length value of 0.001 (complete 0 is impossible), but this still leaves hairs roots as dots when rendered. Is there a cleaner way to delete the hair neatly along the boundary?
  17. Styling Hair generate

    Hi, I have a haircut that is quite precise, so i am using a guide groom on the hair generate to cut a straight line on my characters fringe. How do i have this work with the animated result? Thanks
  18. Hair Collisions

    Hi guys, I have a hair sim that im trying to do, i've got everything setup and working with the exception of collisions with other objects. The hair will collide with the skin surface, but im trying to add collisions with his clothing. I've created an external dopnet and merged in a static object (his coat). I've verified that the collision guide is accurate but i can't get it to collide with the hair wire object. Collide Independent and Collide Codependent are enabled on the wire object. Any help would be gratefully appreciated Thanks
  19. Simulating Fur/Hair

    Hi all, I have a question about simulating hair in Houdini. In maya, they have settings that can be mapped to the different positions along the hair strand. You control it via a ramp. For instance, stiffness curve. You can adjust the ramp so that the root is stiff, but the end tips of the hair is loose. Is there a way of controlling attributes like this in houdini? I want the roots to be stiff and only the tips to be loose. Thanks

  24. Hi guys, I need to export some hair as alembic but it's not as easy as it looks like. I think it need to be converted to geometry first. Do you guys have any idea on how to proceed?
  25. Any tutorials on animal fur?

    Hi, I have seen this lion fur in vimeo and would really like to know how to do something similar,how to achieve that level. There is a tutorial from cmiVFX with a lion as well but you will see the huge difference in result, I need something of this level: Thank you
