Mladen Kevic: 18 posts; Offline

2025年5月23日 16:40:26

Hi everyone, i want to make control rig based on Character Creator rig, whitch have twist bones in limbs.

i tried just to tag with "_Arm" control points (shoulder, elbow, hand) but in autorig component multiik, iksolver use all bones

i recreate similar setup to better represent the issue

so it turns out bended

if i dive in in graph and disconnect this twist bones from IK solver it behave as i would like

is there a way to set in autorig component to use just tagged bones?

thanks,
Mladen

Rigging » Guides properties in 20.5.584

in Houdini 20.5.522, and older, i could add a properties dictionary for "promote", "shape..." and other parameters to be used in APEX autorig controller.

Currently, in 20.5.584, it doesn't work, it sees it only if it's provided over Base.skel.

so i wonder is that some new feature or to report it as bug?

Houdini Learning Materials » rigging a spring

Hi

my advice when rigging spring is that apply bone deform on on curve it self and apply sweep after deformation, in that case wire of the spring will remain consistent.

besides that will be much simpler to weight paint it.

hope it helps

Rigging » i need help with spider leg

thanks, that is what I need from that leg

I'm probably overcomplicated it with the idea to have lookat at tip to align it always to body

and then i stuck to option to work with tags for all legs

was this possible with the editgraph technique from Max Rose?

Hello everyone,

I am working on a short movie where I would like to use an APEX rig for the spider (main character).

I created manually one leg, and now I am looking for a way to make it 'procedural' or to work with tags to create 7 more

the main reason that I don't use MultyIK is that I would like to control the angle of the last section of the leg and to be always on one plane

if anyone can help me I will buy him/her a beer

scene file is attached

I'm trying to rig my test character in APEX, but I am stuck at the LookAt part.

In Apex edit graph there is transform__lookat, but I didn't manage to make it work, and there is no documentation for it.

I followed up APEX rigging Masterclass, there is just pointed to the finished setup in the Lucha and chicken file, which I managed to rip off and use in my setup.

Is currently the only way to rip off finished rigs to be able to make basic rigs for simple characters?

looking forward to more user-friendly modular nodes for building the rigs.

Hello,
I encounter one problem with Karma (first on XPU, but appears that it also affects CPU).

When I work in Stage, and in viewport, it renders as it should, but when try to render frame Range, I hit render to disk (or Render to disk in background) it exports just the first frame and exit render with this error message:

Failed to complete render: exit code -1073741819
Use a Log Viewer with External Render Processes enabled for more information.

I tried to include renderlog, but there is no error in there even if I set the verbose level to 9.

it happening on Houdini indie 19.0.589 py3.

thanks in advance

Hello to everyone, i'm just moving from Softimage to Houdini, so i'm still in learning process.
For me best way to learn is to jump into fire (so i started new project right into Houdini)

maybe it's dull question but i didn't manage the right answer to it. i need to create conveyor (chain like) so i created object i and then add copy node it on resampled curve. So model is done, but i can't find a way to move it along that curve.

In Softimage i would use deform by curve deformer, and let curve that object is copied on follow that shape i want. but don't know what approach to use in Houdini, cause i cant find deforming by curve

Basically i need to create moving Tank Threads

thanks in advance,
Mladen
