  1. Hi All, Im creating geo with a primitive wrangle, each primitive used as a base to create a complex assembly (nothing new for houdini ) However, I would like to create a (handle/container/Null) object (floating on-top the assemble that's non-render'able, im thinking anim/rig like control) the final artist can select to override one of the assemblies attributes ,thus changing its properties. my current concept is to create a centered shaped "poly line" at the each primitive assemble "top" and if a bool user flag is toggled the values are used to alter the assembly stored then in a text file referencing an id so regeneration still keeps the selected ID...... getting more complex by the day. ...Basically a user control surface to alter the primitive assembly. note 1000 assemblies (think forest, with a controller for each tree) Have others come across a solution to solve such a problem ? Any input thankful.. C
  2. Hi. I have basic polyline. Turned into the rig with RigDoctor and animated via Rig Wrangle. I would like to export animation to fbx beacause as far as I understood in order to export fbx animation one needs to use rig system. But nothing works(((. Second question is how to export to fbx copy to points animation. In general I wasn't expecting exorting fbx animation to be so complex. Thanks in advance
  3. Hello all, I try to make a centipede rig that is based on this tutorial from side fx https://www.sidefx.com/gallery/kinefx-spider/ But rather than having only one point for the hip, I have a curve that I copied the pair of legs, so I have multiple hips, everything works perfect except the animation part that he passes the rig from a rig attribute node and then from a transform from path to set point transform, I tried for each loops, I tried wildcards, I tried to run the vop in points and detail, but nothing seems to work for multiple pair of legs, is there a way to pass to set point transform each one of the legs? Thanks a lot
  4. I have been stuck for a couple of days trying to work out how to apply corrective shapes to a houdini kinefx rig. I have a rig set up with multiple rig pose nodes including IK. I would like to get a value at the end of posing of some joints, like thigh x/y/z rotation. I can then say if thigh is rotated in the x by a certain amount, apply this corrective blend shape. However I run into gimble lock issues when I get the rotation of the joint from "localtransform" attribute supplied by the rig pose node. I have read that pose space deformations can be used but I cannot for the life of me figure out how to use it and there doesn't seem to be any tutorials on it either. How would a professional go about applying corrective blend shapes to a kinefx rig? Thanks.
  5. Hi all, I've got a motion editing setup happening, but it gets really slow heavy at certain nodes. I was wondering if anyone here could have a look and point out any efficiency gains I could be making? I've been figuring out a workflow for doing motion editing (animation) of my mocap that gets transferred to a metahuman. (Because of issues I was having with Houdini'd retargetting, I ended up doing the basic retargetting in Maya. But I'm doing the motion editing in Houdini) It's all working well - Thanks to madebygeoff for getting me started - I have all the basics in there; fingers and posture correction. I've also got a constraint setup for locking/controlling the right hand. But when I start using it - by turning the blend from 0% - 100%, my framerate drops a great deal - The arm constraint is very heavy when I do use it. Hoping someone here could have a look and make a suggestion or two. I've attached my hip file, plus an example fbx to plug in to the top. 'cheers, Sim MotionEditing_TEST.hip seq_01_t3_Sup.fbx
  6. HI, my first time to rig a human figure, and using [tetconform] & [bone capture biharmonic] nodes, but it shows error - "No tetrahedrons in reference geometry". Any ideas on how to fix it? (attached file) Thanks, Nelson Rig_figure.hiplc
  7. I use Houdini for effects, I don't know much about character rigs. I have a human skeleton (Houdini bone objects), no geometry. I need to create a simple stand-in geometry for the skeleton (put some simple "flesh" on the bones). My plan: go through each bone, and assign either a tube or a "capsule" (a soft tube, like the one used for capturing geometry), that matches the bone's transform/scale. I can write a Python script, but I thought I'd ask first, in case there's a Houdini tool that can do it, or someone has an existing solution (basically I want the opposite of an "auto-rig", where you start with geometry and create a skeleton for it)
  8. Hey guys! I'm trying to learn character object level (not KineFX) rigging in Houdini. Unfortunately, I find this topic a bit difficult for me, but I still want to learn it. U may ask why? Because I like it, I find it fun:) I already watched a lot of tutorials like Michael Goldfarb rigging series, which I think are good, but I still struggle to go beyond that series. So I would like to ask, if you have any spare object level character production ready rig, better with face rig, that u could provide me for education purpose, so I could decompose it and learn. Please excuse me if u find my request a bit inappropriate, I understand that not many people would share openly their rigs. The problem is there is no many character rigs of good quality for Houdini. Thanks in advance, and dont hit me hard!:)
  9. Why Bullet sucks at Car rig?

    Why difficult to the constraint when using Bullet Solver. I tested in C4D's Bullet Solver. it was superfast to rig dynamic car. The result was Impressive. In Houdini, Standart RBD Solver was easy to constraint. In my mind, I want to Crash many cars in my scene only use a bullet solver. Any Pro guys, Can you do in Houdini? Thank you. Here is how I ***** up the scene. Car_Crash_v001.hip
  10. So far I've only used Houdini for effects so I don't know anything about character rigs. I need a simple, posable mannequin (with fingers). I don't mean a character with a connected skin, just a stick figure with cylinder- or capsule-shaped limbs (head, chest, arm, forearm, thigh etc). In Houdini, is there some ready-to-go mannequin of this kind? Or a standard biped bone rig (with fingers) which than I can "autorig" relatively quickly with cylinders / capsules? Thanks.
  11. Agent mesh modification

    Hello, How can I modify the mesh (or skin) of my agent, I did some modification but I don't know how to integrate them...to the agent setup. https://i.gyazo.com/a2b5ef75d58494087bb1ae142ff7a941.png Thank you for your help. Séba

  13. Shape Key Question

    Hi there, I’m importing a rigged Character Creator 3 model into Houdini using the fbxcharacterimport node in Kinefx. The model has shape keys used to control facial expressions. In the geometry spreadsheet, these are showing up as primitive attributes. However, when I select the Rig Pose node, these each become detail attributes. My question is, how can I go about accessing these attributes, and using sliders on them to animate them in Kinefx? Or do I need to use chops in some way?
  14. So I recently stumbled onto the Motion Path Handles Tool which allows you to visualize your animation curves in 3d space and also edit your keyframes in 3d space as well. I absolutely love this feature but from what i've read and experimented with it only seems you can get this Motion Path Handle UI tool at the OBJ level as it requires you to have the Pose mode selected on the left hand side of the Viewport. I was hoping someone could help me find a way to use this Motion Path Handle tool at the SOP level for a kineFX rig on say a rig pose node or something. If nothing like this exists at the SOPs level yet maybe we could brainstorm a way to either get something similar working at SOPs level, or how to procedurally import joints up to the OBJ level to be controlled with Nulls and therefor could use the Pose tool and the Motion Path Handle animation UI at OBJ level still.

  15. Hi guys, As you can see here, I deformed a curve using "Full Body IK" and "RigPose" nodes. How can I deform a geometry (Tube) with that deformed curve? Thanks for helping. CurveDeformationRig_01.hip
  16. Facial Rig

    Hi all, I've started to learn Facial Rig. Please help me to solve the issues of what I'm facing. First I've started the autorig settings with image “Pic01”. After adding the advanced face module, have placed all the guides, there is no option for the tongue “Pic02”. Then the tongue controllers have got generated in the wrong positions “Pic03” and while rotating the jaw, the tongue gets bending “Pic04”. Then the newly generated locator controls not getting mirrored “Pic05” & also gets affect when the Neck gets translates “Pic06” Have attached the newly HDA “Facial01.hda” Have also created another post in the sidefx forum in the below link https://www.sidefx.com/forum/topic/76576/?page=1#post-328264 Someone please help me to solve this issue and thanks in advance Facial01.hda
  17. Hello everyone, (This is copied from my post at Sidefx's Forum: https://www.sidefx.com/forum/topic/69881/) I have created a rig (and character). I'm trying to use the Pose Library to save my walk-cylce and other animations. Sadly the captured data is all wrong. Parameters like the FK/IK Sliders in my HDA get captured wrong. Several Sliders that don't have any values for some reason get all assignes values. I feel like it tries to capture more than the parameters of my HDA. I have already tried the different capture settings from the Pose Library. It only works when I bake the keyframes, but that would be problematic to work with. I'm on Windows 10 with Version 17.5.391 I sometimes get these Warnings in the Console: Qt Warn: QSortFilterProxyModel: invalid inserted rows reported by source model Qt Warn: QWindowsContext::windowsProc: No Qt Window found for event 0x1c (WM_ACTIVATEAPP), hwnd=0x0x70070. Qt Warn: QWindowsContext::windowsProc: No Qt Window found for event 0x1c (WM_ACTIVATEAPP), hwnd=0x0x3100be. I attached a file with the animated bones. Thank you all very much! (Since this is my first rig in Houdini, I also appreciate every other improvement you might want to add) Rig_Sharable.hiplc

  19. Vellum Clothing on rigged character

    Hi All, I have a vellum setup which involves a rigged character which I will be animating and part of this character uses vellum clothing on the model. I'm currently testing a few keyframe positions to see how the vellum cloth follows the rig, but the cloth is not following my bones at all. Everything welds into place correctly on the character, however when I animate after the weld sim nothing happens. Anyone know what the trick is to get this to work?
  20. Thoughts about this rig?

    Hey guys, I'm traveling to NY in june, mostly to buy new hardware. Did some research and spoke with some friends and this is what I have so far, wanted to give a last check, my main uses are Houdini sims / motion graphics, redshift/octane, zbrush. MOTHER Gigabyte x399 Aorus Xtreme PROCESSOR Threadripper 2950x RAM G Skill TridentZ 3200mhz CL14 (128 gb) GPU 4 x EVGA GeForce RTX 2080 Ti Questions: Does this mother support 4 gpu? a friend told me to be careful about the space with the power supply and stuff. This threadripper is good? or should I go for another? I want the sims to be quickest as possible For GPU, should I pick the Ti or the normals? there's a 300usd difference between each. P.D: I'm thinking about buying via Amazon, but I'd prefer to go with cash, amazon has AmazonCash but with a 500usd limit, so if anybody knows a nice place to buy this type of hardware at good price in NY will be super helpful. Thanks!

  22. New setup - Feedback please

    Hey magicians, Been reading a lot on hardware and got some recommendations, I'm about to travel to buy the new hardware, but still have doubts on it. Mostly on Intel vs Threadripper (been an intel user all my life but heard great things about this AMD). Any tips? made an image with the stuff: Thanks!
  23. Does anyone know how the shelf tools do their eye rigging? I'm looking at the simple biped network and I don't see anything in the lookat parameter of the eyes, and the lookat nodes are in a separate branch from the eye geometry. Any help is much appreciated! Edit: Looking inside the pretransform nodes, I can tell those are being rotated when I move the lookat object. The transforms aren't changing though, and I don't see any expressions or chops references.
  24. Cartoon Eye Rig

    Hello, I am currently trying to recreate/adapt a cartoon eye rig in houdini with help of a blender tutorial. Its basically 4 different spheres all controlled by a lattice to get the cartoonish transforms. Only exception is the actual eye geo where only the sclera part is deformed by the lattice (with a point group)! Now I am at a point in the tutorial where the Iris and Pupil parts are supposed to be pushed out closer to the surface of the cornea as soon as the eye rotates (pic2). In the blender tutorial this is done with a hook modifier. If I understand correctly its more or less the equivalent of a soft transform on a point group in houdini. I tried different kind of approaches with constraints, expressions and VOPSOPs but I just can't seem to get it to work properly. If anyone has any ideas on how to do this I would be very thankful and glad to hear them! Maybe someone knows the original tutorial? Link to the blender Tutorial...paid so unfornately not much to see EyeRig3.hipnc
  25. Hey guys. On my "life goals" list there is this insane task of creating a dynamic car rig that is fully customizable for different shapes and sizes of cars (normal road cars, 4x4, race cars, etc) It should be something like the videos below. The reason behind this is I love cars (obviously) and I want to create a ton of car related stuff in houdini to learn dynamics, pyro, flip, grains but I don't want to spend too much time with setting up a vehicle and meticulously keyframe animate every aspect of it. The videos below look very realistic in terms of physics and they look like they're ready to be lit and rendered, and all these extra elements to be added. Needless to say that my intention is to share the setup if it ever gets this good. So what do you think would be the best way to approach this complex task? Is there already something out there that can be used for this? Ps: in the meantime I'm already downloading every hip and hda that is even remotely related to this topic
