Unfortunately, this is exactly the same setup as in the pdf and in the vimeo tutorial, so it is how SideFX suggests setting up the rig. I tried tetconform and got the same problem and changed the settings. I think the downloaded bgeo.sc file must be bad. I downloaded again and tried the daily build and got the same problem. The rig is present (see attachment)

I am struggling with KineFx. The old bone system was quite reliable. Here is a hand model with skeleton and bone capture biharmonic doesn't assign any weights. I have double checked by adding a visualizer for weights and it is all black. Here are the steps that work fine until the bone capture biharmonic is added. I've tried tetconform as well and played with the settings of all of the nodes without success. Any suggestions?

Hi,
since I’m not at a machine I can not look into your exact case. Also I do not want to guess.
However, some years ago I followed the entire Fur dude tutorial carefully. It was probably with Houdini 18.5. This greatly helped me to learn more about using Houdini in general.
With Houdini 19 and 19.5 strictly following the same turorials will not work. (unless it has been updated for newer versions)
However, I more or less reverse enginered most things to have them work with H19.5 (and to develop my own workflow).
After that I realized that to go beyond function to performance much has to be rewired.
My advice is to start with the model. Then complete the capture. After that go for the rig (controls). This is my current setup and it work great. Don’t follow the tutorial strictly just do things problem oriented in steps.
That said, I still enjoyed the original workflow with 18.5. Things has been updated since then.
I just hope my advice helps.
Edit: You could follow the tutorial for capture weights using Houdini 18.5. It should work, then try to redo it with a recent version. You should be able to run multiple versions simultaneously.

Ok, however I think the author mentioned that the Fur Dude tutorial showed the current state of KineFx back in Houdini 18.5.
KineFx was supposed to be changed since then. It is not really broken, but improved.
However, I’m not sure what your objective and time budget is.
If all you want to do is a quick (and dirty) rig of a character I suggest you check around in the tutorials section.
If you want to qualify as a TD rigger with KineFx you can expect quite a journey. The current state of the tutorials I’ve managed to see (I’ve not seen all) is somewhat in an bit experimental state.
I’ve done a little rigging with Maya and Blender beforecso I know what to look for.
However, today with Houdini and KineFX it is possible to do biharmonic capure, transfer captures and it works fine.
If you really want to learn the depths of rigging make sure you give it a lot of time and patience.
Can’t you download the finished Fur dude asset to Houdini 18.5, and check it out?

I've rigged in Houdini with bones, softimage, Modo, and C4D without problems. Either I am missing something with KineFX or it is buggy.
This is not a parenting, controller issue, hda, weighting, promoting parameters, etc. it is a failure of capture.
Edit: it looks like this is a visualization issue. I set the visualizer to single bone capture and the capture seems to have worked.

Now I just destroyed my capture to redo a biharmonic. It worked on first attempt. This is Houdini 19.5.403.
Make sure your inputs are valid. For example the tetembed must wrap the entire source mesh. Check Enlarge Offset.
The other DCC:s you mentioned have a more predictable workflow than Houdini. Since Houdini show you all parms it is easier to break things.

To try to force a display redraw I tend to press arrow icon and then the tool specific arrow below (do not know the name, maybe ”manipulator” something). This will ususually give a view update. I’m aware that users complain about a generic display thing and believe that sidefx already do RnD on updates. I’m so used to this now that it is a habit.
However, somehow I expected that you checked the geo spreadsheet thing for attributes. It should show the weights also without a view redraw, no?

I'm checking your scene. For a start. In your skeleton mirror node change L_ to l_ and R_ to r_ otherwise your mirrored joint (bone) inputs are corrupted. Then if you add a capturelayerpaint node after bonecapturebiharmonic1 you can not select and see your Capture Regions to paint them.
That said, there might be something more to this.

Nah, if you change the L_ to l_ etc thing it seem to work as expected on my end.
However, I just discovered that my Houdini embedded screen record tool will destroy the capturelayerpaint node. Gah! So I can not record any weight painting unless I figure out what is wrong. It has nothing to do with your file.
Edit: Now you should be able to visualize also, because you can select your regions, no?

Thank you very much! It appears there are two separate issues. The inability to capture was user error due to my capitalization. But there is a separate display issue. If I set visualization to bone capture, it only works if I have single bone visualization selected. The biharmonic capture node itself is supposed to show the visualization. I think this is the bug that SideFx has logged.
Fortunately I was able to do weight painting, add a delta mush and set up a rig for the hand model, so all is good.
